Hibernate in Java - What Should Developers Know?
As the name suggests, Hibernate Object-Relational Mapping or ORM is an object-relational mapping library that is used in Java. The library provides a framework that helps in mapping object-oriented models of domains. The main objective of Hibernate is to solve the object-oriented impedance issues through the process of replacing the direct persistence-related accesses of database with functions that are involved in high-end object handling.
The primary feature that Hibernate comes up with is a unique mapping ability from various classes that are used in Java to the database tables and the same from Java data types to the SQL data types. The library also provides a string of retrieval facilities as well as a high end data query that facilitates handling the backend features. It also generates SQL calls, while making the lives of the developers easier, by automating set handling as well as object conversion. Besides, applications that use Hibernate also support SQL database with hardly any performance overhead.

Why is Java preferred over .Net by enterprises?
The question of whether to prefer Java (J) over .Net has been disturbing the fraternity of developers for quite some time. While some say that it is better to vouch for .Net rather than opting for ‘J’, another school of thought says that it is preferable to use ‘J’ instead of opting for .Net. Let us discuss the reasons for which the enterprises nowadays like to prefer Java over .Net.
Open Source
The fact that Java is an open source language clearly implies that users will not need to pay any licensing fees to Oracle for developing any software using ‘J’. The language is easy, quick to learn and most importantly, complete with a number of value added features and functionality that meet today’s needs. On the other hand, the development of .Net is pretty time consuming as it is far more complicated than ‘J’. Moreover, .Net makes you shell out a substantial amount of money, albeit the presence of a string of free tools. Most importantly, .Net is often plagued by the presence of a number of features with limited functionality.
The advantage that the companies enjoy while using ‘J’ is that they are able to slash the cost of development by a considerable amount with the use of a specific framework for open source software development. Naturally, for the enterprises that are running on a shoestring budget ‘J’ is the best option to vouch for. Besides, since ‘J’ is an open source platform, it helps the developers in doing whatever they feel like and create software solutions as per their will, with the support of a number of development tools that are supported by ‘J’.
Java is platform independent
When it comes to developing cross platform software, ‘J’ is absolutely indomitable. The software systems programmed with the help of ‘J’ codes are executable and can be run across multiple platforms. This is because JVM implementations are cross platform and are compatible with all the major platforms.
When it comes to software development using .NET, Mono can be used for building applications that are compatible to all the major OS. However, what is missing in .NET that ‘J’ comes up with is the user-friendly approach. This is where ‘J’ scores over .NET. Frankly speaking, Java is indeed an ideal platform for software development that makes the entire development process much simpler as well as less cumbersome.
Active Community
The most important part if Java is that, the solutions are absolutely free of cost compared to Microsoft, which charges a hefty amount of money for each and every solution. Java, on the other hand regularly keeps on updating itself with new features, besides improving its functionality as well as effectiveness that comes in handy while creating Java platform. This implies that every software as well as applications can enjoy the advantage of the very latest state of the art technology, without any extra expenses whatsoever – a reason that is enough for the huge popularity of Java.
Safety and Security
Java is more popular because of the improved version of safety as well as security than any other programming language including .Net. Java comes up with certain features that include automatic null checking, verification of each and every byte before execution, run time checking of security along with a string of similar kind of features, which help the developers in building secured apps.
Besides all these, Java helps to infuse a tinge of intelligence in every aspect of our life by changing things that are around us or things that are indispensable parts of our modern life like various electrical or electronic devices, homes, appliances, cities, automobiles and other items that we use in our day to day life.
There are surely other programming languages that are quite useful and are regularly used, but when it comes to discussing about any matured software programming language, nothing can be as handy and as useful as ‘J’ and this is the reason enough that the language is more acceptable and adorable than any other programming language including .Net by the modern enterprises.

Ways to enhance security of Java web applications
Through web applications, end users are provided with client access for server functionality. Mostly the applications enforce intuitive, simple security policies. However, despite that recently there have been a number of attacks on them like cookie theft, cross-site scripting, browser hijacking, session riding, etc. So it is high time that we rethink the security strategy of web applications and enhance it so that it becomes harder for security breaches to take place.
Input validation- This ensures that whatever data is entered by the users or has been derived as input from applications is without any security hazards and clean. This is a very critically secure coding practice which should be implemented. The design of web applications aims to perform functions or set of functions according to user input. Generally those who attack are also users and commonly the applications used by them do not validate input since they enter arbitrary inputs to successfully perform attacks. Malicious file execution may also result due to lack of input validation. So applications should have inherent capability to validate input for protection against attacks.
Defence in depth- This defence strategy for computer systems aims towards building multiple protection layers so that possible attackers may be isolated from whatever you need to protect. To make this system more secure the approach should be combination of factors that can hinder the accessing attacker from the target; the goal should be made costly so that it proves to be unworthy for him.
Mechanism economy- This principle is a very important one and is often known as Keep It Simple, Stupid or KISS in short. This is due to the fact that architects as well as developers keep this in mind when building solutions so that they are focused on the main problem. This helps in the reduction of possibilities of attackers finding ways of accessing the application which are not foreseen or tested.
Rules validation as well as data entry- These must be performed in back end always even if the validation has already been done at front end. For web applications, input validation must be performed by using JavaScript. Validating rules both on front as well as back end allows you to have an environment which you can completely control regarding what may be or may not be allowed.
Enforcing minimum privileges- Each user and each program must be operating within the minimum privileges that are needed for their capability to perform the related duties. When this principle is followed, the damage that may arise from security breaches is limited so that the interactions between the system components may be reduced to minimum. This facilitates access control and audits case of failures or errors.
Setting standards-based fault- This helps in preparation of architecture and functionality so that decisions may be based on permission instead of exclusion. An example of this is using white lists and not black lists.
Using manifest attributes- A large number of manifest attributes helps ensure that your Java applet or application’s security is not compromised. Permissions attribute may be used for ensuring of the permission level being requested by the application to be exactly what has been specified in JNLP file or applet tag for invoking of applications. Codebase may be used to restrict JAR file’s code base to specified domains. To identify locations where the application may be found, you can use application-library-allowable-codebase. You can also identify domains from where calls may be made to the application by JavaScript code; this helps deny access of unknown JavaScript code to the application.
When considering the security aspects of Java applications one thing that should be kept in mind is that security should be implemented at every level of an application. It may not be possible for us to have applications that are 100% secure but implementing a certain amount of security measure will help eliminate some basic risks.

Some of the biggest myths about Java
Java’s first version was launched in 1995 and since then several versions have been launched after fixing bugs as well as making improvements. Despite, being in the industry for such a long time, there are a lot of myths associated with Java since there are many people who will believe exactly what they want to believe, ignoring all better judgement. There have been much speculations, discussions as well as arguments related to various aspects of Java. This article aims to bust a few common myths that are associated with this language in the minds of people.
It is slow- A few people feel that this is slow in the start-up times, especially when compared with C++ or simple PHP applications. The applications may take some time for loading but the same can be said for .NET or other such big libraries. However, the latest Java update ensures that the loading time is much faster in comparison to the previous models. There is no point in comparing it to other programs as each has its own individual set of problems associated. C++ is the fastest but Java can be said to be faster than many other languages.
It is dead- This is said by a few since it has been in the industry for almost two decades and its last major release had been quite some time back. However, it is not fair to assume that it is dead just because of that since similar instances of no major releases can be found in C++ or Microsoft Windows. Other languages may evolve quite fast but you must remember that these languages are quite new, so they need much polishing to be done. Some people also cite that the language’s popularity is slipping through some indexes or statistics. But if investigated properly then it may be seen that these surveys are actually incomplete. They do not show the full truth, just investigate a few parameters.
Your hard drive may be read and files deleted by applets- The truth is that when applets attempt to access any local file, then a SecurityException will be thrown. The applets will crash if it is uncaught but without any file access occurring. Digitally signed applets that are granted with additional privileges, is the sole exception to this. A dialog box will be displayed by your browser to ask whether the applet author’s identity is accepted or not. If unsure it is best to choose no, to be safe.
Applets cannot be relied upon as differences in Internet Explorer and Netscape does not make writing stable applets a stable proposition- Different JVMs, various versions and kinds of browsers result in the varying behaviours of running applets. The users as well as developers may find the differences frustrating but the best solution for this is using single JVM to use across all browsers. This can be achieved by virtue of Java Plug-in which can bypass the JVM of browser to use its own, resulting in uniform performance.
Web browser is a must-have as Java cannot run without it- There are several forms of the code. Users are mostly familiar with applet running inside web browsers. But it is very simple to run Java application like normal programs. All you have to do is install JVM from some vendor to run the programs. A web server often runs Java servlets which may be termed as replacements for ASP or Active Server Pages as well CGI scripts. These are quite fast in fact and more efficient that CGI scripts.
Many people do not realize it, but there is a lot of potential in the language. There is more to the software than just applets. They are quite secure and hard drive will not be deleted. In case of any problem, installing plug-ins will help you solve them.

Is Java Most Suitable for Enterprise Applications Development?
The Java programming application has become the most preferred choice for large-scale, steady business schemes and is becoming more and more popular in embedded systems for portable computing devices. With the arrival of faster processors as well as not so costly mass storage devices, Java is allowed to transcend the original limitations of the language, and this independent environment makes it suitable for developing global enterprise applications and web services. Moreover, many portable devices and smaller systems can benefit from apps written in this programming language.
Java as Dead-End Enterprise Application Process
In earlier days when Java was yet to be invented, one of the major industrial trends was to raise the productivity of end users as well as developers. For instance, to develop business applications, fourth-generation programming languages (4GL) like Progress, Uniface or Powerbuilder rendered professional developers various quicker means than using C, C++, COBOL or Pascal. Tools like Lotus Notes, Dbase or Visicalc provided end users with the unparalleled ability to create mini-applications without any requirement for development teams. In the early '90s, such productivity trend was thrown into a tizzy by the web. Now, enterprise application developers as well as software vendors need to write an entirely new generation of apps for the internet. This way the 4GL along with Internet forced developer productivity had to take the back seat.
For Web Apps Java Was at The Right Place at The Correct Time
To develop embedded systems, Java was designed in 1990 as an easier choice than C++. In 1993, the invention of the WWW initiated a meteoric change in Information Technology application development platform. Leading companies moved further and took advantage by marketing “network” servers like hotcakes and thereby offering Java as the platform for Web application development. Many other software vendors were caught off guard and for enterprise app development Java became the de facto web development standard.
Moving Ahead to Escape Drawbacks of Java Development Platform
This application has served its purpose and now it is time to go further as for enterprise-level app development, it seems to be too tricky or complicated. There are certain factors as to why business application development professionals must plan their escape from Java:
So far as enterprise apps development is concerned, there is no denying that Java plays a major role despite tons of rise and falls. For the programmers, it brings a number of benefits including scalability, ample flexibility, security, robustness and of course versatility within the application development frameworks. However, like any other application platform, Java too has certain limitations that can be easily retrievable using faster processors and less expensive mass storage devices.
With this programming language, you can invent almost any form of enterprise-level application. In today's world, many developers prefer using Java to build unprecedented business solutions by leveraging the features and benefits of this fantastic application platform.

- With sophisticated business scenario as well as requirements the pace of change has increased.
- Development authoring is restricted to programming languages. Even though this platform supports additional programming languages such as Jruby or Groovy, the fundamental platform limits innovation to the conventional services offered by Java. Many new programming languages can be invented, but all of them should be applicable in the underlying environment.
- This platform botched the presentation layer as JavaFX is a failure while Swing is a nightmare. For pre-Ajax user interfaces, JSF was designed in spite of some implementations viz. ICEfaces incorporate Ajax. In the presentation layer, new UI approaches are found to have a steady stream that reflect Java's lack of leadership.
- The Java frameworks show complexity. Struts, Spring, Hibernate and other environments reveal deficiencies of this programming language rather than its strengths. Simply to do the basics, a future platform must not need a cacophony of the same approaches.
