Generating Reports with Jasper Reporting
Report generation is one of the most important tasks for a programmer although it is not at all popular among them. Reporting is basically making the users aware of the certain instances and data present in a program. It is in no way a task that programmers look forward but in any case it has to be done. Before there used to be commercial software for all these reporting purposes but now the Open Source community has finally made their own reporting tool for Java called JasperReports and it is a great alternative to commercial reporting tools for Java programmers.
JasperReports is in no way a tool made just to help users go open and free instead of buying commercial products, instead it is very much a better reporting tool in most cases! For instance it has got all the features that any commercial tool has like generation of dynamic reports, retrieval of data via the Java Database Connectivity (JDBC) on top of supporting all the basic programming elements like variables, expressions, constants, parameters, functions etc. Moreover, it contains some extra features which are much advanced like sub-reporting, script generation and building your own custom data sources. Hence it shows a great level of planning and maturity in it.
JasperReports is basically written in XML and therefore it follows all the nuances that come with XML also. It can be categorized mostly into three sections: the first sections where all the parameters passed are to be included, the second section where the query for the processing of the data is to be entered and lastly the section for displaying the report. Each report section is sub-divided into a number of categories called bands and each of them in turn possess a handful of elements for signifying the position, size and magnitude of the instances like variables, fields and parameters.
There are three types of objects present in a JasperReport code that take care of all the operations performed in it. They are: JasperDesign for designing a report’s definition, JasperReport which compiles the JasperDesign object and JasperPrint for generating the actual report by filling in the data into the compiled JasperReport object. All of these objects can be either manually defined or can be used directly from their XML templates. Also they can be accessed and used from any piece of code used in JasperReports and this whole filling, compiling and reporting process can be done from the classes present in the JasperReports tool.
Using and installing JasperReports is also very simple and can be done easily by downloading the application from the JasperReports website and it is completely free! It can both help people in building a new report for any application from scratch or can add extra functionalities to the existing ones. Most of all it is an endeavour by the Open Source community to give the members of their community something new and alternative to the widespread commercial product and what better way to do that than helping the Open Source Java Programmers.
Jasper Reports and MySQL is a great combination when used with Bounceweb Hosting!

Network Traffic Control
It is the process of reducing bandwidth congestion by managing, controlling prioritizing and reducing the flow of traffic. Traffic management is more important than any other aspect of website hosting because the smoothness of running of the website depends on how well it is able to handle traffic during peak hours. Too much traffic can cause latency, packet loss and even end in the server crashing.
There are various techniques used for efficient traffic management like traffic shaping or packet shaping, bandwidth management, putting quotas, patches. It is necessary to first measure the total network traffic and identifies the primary causes of network congestion in order to use the above mentioned tools effectively.
Network Management techniques
A method which ensures that large downloads don’t get in the way of net access by hogging the entire bandwidth all day long. This is done by generally limiting the bandwidth allotted to that specific file.
It is very efficient in improving latency and increasing available bandwidth. On the basis of certain criteria or priority, some kind of packet data is delayed so as to optimize speed for other packets.
General method of implementation of packet shaping includes delaying of metered traffic, such that each packet has to comply with traffic contract. And this is done by implementation of leaky bucket / token bucket methods.
Another method of controlling and measuring the traffic on a network link so as to avoid filling the capacity of the link and prevent congestion.
This is done by Traffic classification- dividing traffic into specific groups on the basis of some criteria such that other tools of traffic shaping may be applied to each individual class.
When the number of packets exceeds the allotted traffic size for a certain bandwidth, the excess packets are either dropped or marked for future transfer.
Persistent Session routing policy
Requests from the same user are routed to the same server by continuing the session.
Content based routing
Requests are routed according to the content it asks for.
Server based Routing Policy
Requests are routed to servers based on the number of pending request and overall traffic. It is assumed that each server has the same content and is able to meet any request. This is very useful in reducing workload by regulating the number of connections to the server.
Protocol based routing
Requests are routed based on the protocol used by the client. FTP request go to FTP servers, HTTP goes to HTTP etc.
In order to keep PCs up to date with security fixes, a lot of patching has to be done. Worms and viruses are responsible for a lot of bandwidth clogging and congestion. That is why it is necessary to remove them early.
Another way of reducing load on servers , is by limiting the bandwidth, by giving specific quotas of bandwidth to every user, for a specific period of time. This is generally don in universities and other shared networks.
Bouncweb Hosting arms you with the latest technologies to control your website traffic.
P2P Networking – the fast way to connect
A Peer to Peer network (often shortened to P2P) is a connection process where two or more PCs connected to each other can share resources , peripherals as equals without the need of a central dedicated server.
It is a distributed application architecture that divides tasks / workloads among Peers. Peers refer to the workstations connected to the P2P network which are participants in the application and which are all equally able to perform any function necessary for the network. A computer connected to this network is called a node.
The reason for the popularity of a P2P network is that it can be set up anywhere- Homes, offices, online business etc. The only requirement is that all the participants of the network should be using the same or a compatible program, (client), to connect to each other.
The first P2P app was Napster, released in 1999.
In a P2P network each node is essentially a client as well as a server, thereby eliminating the need for special high performance machines to act as servers. Accessing files is basically governed by the user setting different sharing permissions on their own machines.
Due to the inherent characteristic of P2P networks it is the clients who are responsible for providing network resources such as bandwidth, system power, and storage. This feature is tremendously useful to original content distributors, because it reduces the setup as well as running costs very small.
Due to the decentralized nature of the network, if one peer ceases to function properly, it does not affect the whole network. As long as there is even one properly functioning PC, the network will be alive.
Also important to note is the lack of a system administrator or a central authority. This leads to a more efficient and stable network owing to lack of a full staff needed to ensure smooth running.
Just like any kind of file sharing system, users are vulnerable to malicious attacks from harmful content that may allow remote access to the user’s PC. This can even affect the whole network.
For one thing, sharing files with random strangers on the internet does call for some sort of caution. It is recommended that you at least have a firewall or an antivirus scanning each of your downloads to protect against potential backdoors and malware. Another way would be to just use trusted sources.
P2P networks represent one of the most important issues in the ongoing controversy of network neutrality. Internet Service Providers have been known to cut off P2P file sharing traffic on account of its high bandwidth usage.
But still we can expect this form of networking to only grow and grow more for its pros far outweigh its cons.

Data protection and privacy under VPS
Today, in the fast running world of web hosting, data security, protection and privacy are of extreme importance. For a general security – conscious user, Virtual Private Server (VPS) server, is a splendid option, which plays an important role in the data protection and individual privacy. The name Virtual Private Server itself signifies that the server is basically centered to the privacy of the information and data security. There are kinds of advantages that a VPS offers in terms of data protection and privacy.
Indeed, website owners do have infinite options in terms of web hosting. The hosting services now-a-days have become exceptionally branched out over the few past years. Data security and privacy are extraordinarily important, especially if the site is of say, central importance for the business of the clients. E-commerce pages and websites which deal with the private data of clients and visitors require higher rate of information protection and data safety.
A VPS can be said as independent space in web which is dedicated exclusively to clients’ website and requirements related to data storage. Even though many other VPS servers are executing on the same setup, all of them will run independently. Even it is possible to undergo a reboot without disturbing the activities of other virtual private servers running parallel to it. Because of the reason, that each Virtual Private Server hosting setup comes with its independent space stands for a minimized chance of security violations and problems.
Data collected and used by the servers
The VPS servers generally collect some data and use them for analysis of the users visiting the sites. They collect the data also to prevent fraudulent or fake signups, minimize the risk of charge backs and to take the feedback. Some relevant information which they collect are: Name and contact information, transaction information, visit data and survey data. They generally do not share the information for the sake of privacy and security, but in some cases they do share the data of the users, like legal (police) investigation related to criminal activity, court orders, operating with the sister companies, etc.
Other security functions
The grade of security and protection in VPS is customizable, another prominent advantage which makes VPS the perfect hosting choice for the requirement of website. The administrator has total control over the security and protection features precisely due to the fact that the software is not dependent on the hosting requirement of other clients. The security advantages of a VPS hosting package avails regardless of the selected operating system. It all depends upon the degree of data privacy which the operation of website operation needs. The updates and upgrades which the other clients function keep the virtual hosting space isolated. The data can be backed up easily to provide even greater certainty as well as professional security.
The additional advantage of customization makes the VPS hosting an easy and famous service among the clients of web-based businesses and e-commercial websites. Software in the server can be installed and removed much effortlessly. In the issues of other hosting options, optimization of server performance is also much easier. Virtual private servers are the most suitable option for the website owners that give security and data protection maximum priority.
Disaster recovery: Mantra to win the battle
This concept was originated in about 1970, when the process and methods related to arrangement for recovery upon any natural or artificial disaster came into practice, later it came in spotlight as the dependency of organizations increased with more complex computer setups and other company implementations. These days, most important corporates reserve a different and separate fraction of their IT budget merely for this disaster recovery. To execute a successful and reliable recovery processes are critical even though after a good planning. Selection of the suitable disaster recovery data center can be called the main aspect of the whole process. Avoiding those areas which are prone to disaster is necessary, for instance the Phoenix metropolitan area is said to be one of the safest cities in the US in contrast with it San Francisco and Miami come under the category of “endangered” . The chance seeking hackers always have an eye on their next victim; many natural calamity like earthquake and flooding usually malfunction the availability and hardware of a site, which may lead a website to crash. The involvement of a large scaled capital and labor in a website makes the disaster recovery plan so important to be implemented.
Major prevention strategies
A natural disaster cannot be prevented but the artificial disaster of the site can be prevented by going through certain strategies and best possible steps. Some of them can be concluded as:
Take a backup
When a website crashes, it leads to the loss and damage of many important data as well as much confidential information destroying all the commercial and managerial balance of the corporation. So, with a backup plan, these circumstances can be avoided as the information are “copied” and saved securely and are retrievable if needed in the future, which dramatically reduces the future hassles.
Transferring data to different servers (accessible)
If the data is transferred to a different server or location apart from the present one and can be accessed remotely, then the problem of data destruction can be solved up to much extent. Many web host providers facilitate this feature to reduce the strain and burden of the user, assuring the safety and security of data for the unavoidable circumstances. The user must take care that whether the accessibility is provided by the company or not regardless of the location of the user in the world.
Clouding the data
The data can also be saved by those circumstances by clouding the data and information in any secure and trustworthy cloud providing sites. But the disadvantage in this process is that even the cloud server does not guarantee the protection from those disasters which may happen to them.
Before following any of the above steps, the most important step involved in it is “Data Encryption”, which is a critical as well as essential process in the way of data security and conservation. Data encryption ensures the user that data or files and information are not easily readable and understandable as compared to the plain text, which effectively reduces the possible threats of data leakage, information theft and privacy violation. Following the steps a user can reduce the disaster effects and other circumstances.
With Bounceweb Hosting, you are safe for any disaster recovery management initiatives.
Green Web hosting: Let’s go take back our green mother planet
Why Green Web hosting?
The statistics of World Internet usage reveals that the spider web of Internet is still frequently exploding worldwide at the rate of 400-1000% increment per year. And hence, the energy consumption for operating those servers and the relevant infrastructure setups is also day by day increasing. It is approximated that if the energy consumption due to the web hosting goes on rising at the present rat, by 2020 the web industry will be one of the most polluting industries in the field of business. The environment of earth has been decaying continuously and we must not be late to save it. Many web industries have taken some action and played their roles in helping by recycling materials and reducing energy consumption. Green hosting is a kind of hosting which uses eco-friendly sources of power for their regular functions and activities.
In short, the web hosting companies are indirectly trying to save our mother planet by reducing the amount of carbon emission.
What is Green web hosting?
While providing the hosting facilities, the Web providers consume a great quantity of energy to data centers and power servers for facilitating 24×7 services. Many other relevant facilities like enhanced security and cooling controls and setups also need a huge amount of electricity, which has a negative effect on the environment. As the name implies, the Green web hosting is the hosting solution which is powered by eco-friendly resources. These are those hosting providers which are powered by only renewable sources of energy like wind power and solar energy.
Advantages of using Green web hosting
If we are going through Green web hosting, certainly there must be some great advantages which make the use more efficient and preferable, some important of them are:
1) Harmful carbon dioxide (CO2) which is released in the atmosphere is reduces due to the practice of this green web hosting as well as these companies also earn carbon credits.
2) The artificial energy sources would be saved and could be used in future, and hence the man work would also be decreased.
3) The website download time and function delay is minimum in this type of web hosting and unlimited email accounts and memory space are also provided.
4) The green web hosting is one time investment and a cost effective technique.
5) The greatest advantage would be the feeling of satisfaction among the people, by living in the greener and healthier environment.
The Green web hosting industries may run at busy and complex daily operation costs with respect to many other host providing companies but the thought of making a paperless and eco-friendly company using the renewable sources energy makes the sense of encouragement. When it would be implemented in more than a single company operations and functions, it could decrease a lot of waste materials as well as reduce a lot on consumption of energy which will immediately help in saving and maintaining the nature. So, if saving the earth comes with some investment and long routed process, then it should not be a big deal to pay, if we are supporting a green and clean environment with the green web hosting companies.

Internet safety: Keep safe, Be safe
Internet now-a-days has become such a necessity for the general body and hence the use of internet as the result has reached at its pinnacle. Therefore, a safe and sound implementation of internet must be undergoing so that there must not the violation of privacy destruction and data stealing. Gone are the days, when the internet safety was concerned about only the protection of computers from malware and viruses. Today, the internet’s immense range, changes in technologies and growth of social nature constantly have made people more endangered particularly to privacy violation, identity theft and even self-harassment. So, some steps must be definitely taken in account in order to rectify the issues of safety.
The important steps are as follows:
Protection from Viruses and Malwares
A good and basic defense against the general threats on internet is practicing a good antivirus program, or anti-malware software. It protects the computer from corrupt websites, tainted email attachments, net worm viruses, spyware and many more. In the dense traffic of antiviruses in the market, a antivirus software can be used which must protect against fishing sites, viruses, malware and has a good firewall, spam filtering as well as anti-spyware tools with latest updates.
Protecting e-mails from Scams and Spam
Now-a-days, a great no. of emails are spam, it’s because it’s very inexpensive and easy for a spammer sending an spammed email to many people simultaneously as well as anonymously, and the malware phishing and scams are generally included in spam. So certain steps must be carried out to effectively reduce the spam in our inbox, like:
- Using a spam blocker in the e-mail.
- One must not reply to the spams and must not follow the links.
- Keep turned off the image and the preview pane.
- Check the spam folder and clearing those spams regularly.
- Turn on the firewall of the pc.
- Never download the unexpected attachment if required download it after scanning.
Protection against monetary and online transaction crimes
The internet has facilitated the common public with shopping, banking and other financial transactions online very conveniently. But as far as the money is concerned, it must be made sure that the transaction operation is in safe hands with some precautions:
- Before sending any sensitive or financial information online a user must confirm the “https” before the site address, which assures that the information is encrypted.
- Notice the “security symbol” in the address bar (shown below in Mozilla firefox), which is a verification of a secure website by the browser before any transaction.
- Compose strong passwords and never share them.
- Find the SSL certificate of the site and look for the “issued for”, “issued to” and “validity”.
- Use a pop-up blocker, if not then never reply to the pop-ups messages.
The steps for avoiding password misuse and theft must be implemented as passwords plays a very important role:
- Never use the same type of password for every account.
- Avoid using the predictable password pattern.
- Include symbols, numbers and both upper and lowercase alphabets.
- Never set passwords at any disclosed place or at public view.
Protection against the cyber addiction
Cyber addiction is mushrooming day by day which does not only kills the precious time of the people, especially teenagers but taking many shapes of internet crimes also these are the major sources of data theft. It can be reduced by the self-assessment and a few efforts of users, like:
- Avoiding online gambling
- Avoiding online gaming(money involving).
- Avoiding porn sites, as these are the main sources of major Trojans and viruses.
- Using the social networking sites consciously.

Server data protection: Get rid of the traditionality
These days, the growth of data is exploding like a big bang which is making the protecting and security of data more expensive, difficult, unmanageable and unreliable by the normal traditional backup methods. Many organizations and corporation are following the cloud data protection solutions and going through virtualization for the reduction of the costs involved in infrastructure and complicacy of server backup. IT professionals are facing many challenged issues related to the protection of critical and important business data. Yet there are significant differences between the traditional methodologies of system backups. The conventional server backup procedures are not always suits to the challenge as the data can only be recovered if it is been introduced before backup point time. Further, the traditional backup plan could be time consuming as well as the involvement of valuable IT professional, which could be deployed to perform other mission-critical operations to enhance the business, effectively decreases its overall efficiency. And when it comes to the data protection especially for any organization, traditional methods are simply unable to provide complete protection. Hence, here comes the need of more dominant data protection steps, and thus many techniques are acquiring the market these days. The users must decide the product by comparing the features of the plans.
It is necessary to select the best possible plan for server data protection, which must be user friendly, simple and of course better than that of the traditional techniques. So, a good server data protection technology must have some features to make the process efficient and time saving, some of them can be listed as:
1) The server protection setup must be fully automated, simplified, reliable and secured.
2) Build in security for the open database and files.
3) Web based management.
4) Robust meaning- based search or semantic based search.
5) Recovery must be fast and easy enough.
6) Must have special understanding of data to escalate back-up value.
7) Virtualized environmental support.
8) Facilitated with patented data reduction technology.
Protection by Instant file recovery methods
There are many file recovery plans which can be used for the data protection. These setups replace the Recycle Bin of the operating system with a Recovery Bin which actually conserves all deleted data, even those which have been typically bypassed by the Recycle Bin. These methods actually work in real time, unlike the Volume Shadow Copy (VSS), capturing every version of file, so the data could be recovered instantaneously in exactly the same state with the preciseness of time of deletion. They could even recover the specific type of older files like the documents, texts as well as emails.
1) In this process, cloud data protection can be achieved together with long term offsite memory.
2) It provides the real-time, legitimate collection of data for recovery and backup, data analytics, and effective data discovery.
3) Fast and reliable source of data holding.
4) It presents the instantaneous recovery with the point of the clock by continuous backup process.
5) Costs falls dramatically, as it replaces many traditional backup plans with new and efficient sources of recovery.
6) It removes the load of the complicated regular backup chore.
There are many products for the server data protection such as Microsoft system center data protection manager, iron mountain data protection, undelete server (for Data recovery), etc. which can be used to make a better and reliable data structure.

VPS Hosting: When to make a leap
Virtual Private Server (VPS) Hosting is an easy, inexpensive, modern and advanced approach to the partition of physical servers into multiple virtual machines. It is going to be the future king of modern and advanced hosting due to its facility of providing the functionality and power of a high-end dedicated server at much low price as compared to the market. A VPS Owner gets a separate machine with root access and with dedicated CPU and RAM. In the hundreds of ways to host a website, some corporate and individuals select to carry on their own software and hardware, the most general way of hosting a common website is by making a optimum use of shared web hosting. VPS is a step ahead in the field of hosting hierarchy. It looks to the customer as a stand-alone system and it is managed with such a familiarity like its own one. There are certain situations and symptoms which decides the right time to make a leap. But before making a leap to VPS, it is necessary to upgrade the system to the advanced and compatible version.
Know the right time to make a leap
There are some certain circumstances which indirectly recommend the user to move to VPS. The must take them in account in order to make a leap to VPS and to improve the business strategies, some of them are mentioned below:
1) If the website has become too busy with material traffic, and processing power of sharing and bandwidth with many other sites is not providing the required functioning and performance. The main indicator can be concluded as the dull reactivity of the website.
2) If the business is going to expand or escalating quickly and sudden increase frequency requires the upgrade of the server capacity.
3) If more control is required over the server, especially over the root access, so that the server content and its performance can be properly managed, which is very difficult in the Shared hosting service.
4) When there is a need to run special programs and applications, like real-time gaming or media streaming. It could also be done with shared hosting, but the resources and performance may be very limited and often the hosting company limits the setup to run such intensive applications.
In spite of many situations compelling to make a leap to VPS, many difficulties may come across the user, resolving them may result a better VPS hosting. Some of them may be with respect to shared hosting listed as:
1) The price tends to be little more as compared to the shared hosting plan.
2) If enough traffic is there and much amount of money is concerned, if you have to make money you have to spend money.
3) Some additional administration and maintenance is required if you are accustomed to the shared hosting, it is more complicated and you must have some administrative experience of server.
Although, the shared web hosting is adequate to some extent for most individuals and some sector corporations with basic requirement like hosting a blog or provision of some informal web pages. But the most significant difference is that, a VPS gets guaranteed resources in other hand a shared host website never does.
