  • Spring as a solution to J2EE

    Out of many reasons of J2EE for not being an exhaustive success, one is its complexity. While using this platform, it requires tedious effort to develop which seem a bit bothersome when it comes to evaluation of its performance. The Spring framework makes development of J2EE easier. This open source framework, although applicable with many other platforms, is especially useful in developing J2EE application.Spring Java application Framework

    The use of distributed object model makes J2EE code complex and repetitive. Codes like JNDI lookup, Transfer Objects and so on appears to be quite “not appropriate” to be maintained and written for any active use in the application. These practice of code duplication and excessive complexity could be addressed by bringing J2EE from the realms of a tool enabled code generator to a framework model of application development. Frameworks are flexible as single pieces of codes can be modified without any change to many classes. Spring Framework minimizes the complexities of J2EE coding by simplifying the overall process of development.

    The basis of Spring Framework is Inversion of Control (IoC) that configures application components and manage Java objects. It passes required objects to the program beforehand instead of a need to write lengthy codes to create specific functions. Framework codes calls application codes making the process a lot easier than that of application codes calling framework codes, for which lines of class defined codes are required.Spring Framework

    Spring follows aspect oriented programming. Therefore, this could be used as a versatile method to affect a large area of classes and object hierarchy. Unlike object oriented, aspect oriented programs can address particular concerns of the system. Transaction management, failure monitoring and logging are some of the typical aspects of a system. Spring unifies several transaction management API’s and coordinates transaction for Java Objects.

    Therefore Spring is a right choice for working with J2EE. It simply solves the issues that made J2EE unpopular.

  • Most Amazing Java Development Changes for IT World

    Java has revolutionized the world of Information Technology since its release in 1995 by Sun Microsystem.  It has become the core competency of Sun Microsystem. The language derives most of its syntax from another very popular language C and C++. To run  program the system needs to have JVM i.e. Java Virtual Machine.  The JVM converts a  program to bytecode and then runs the file irrespective of the computer’s operating system. This is the convenience that this language provides. A program written in his language can be compiled and executed on any computer system irrespective of the one on which It is written. This called the cross platform functionality.

    It has proved itself to be one of the most popular languages mainly for client server  based applications. The client server applications are those that require the interaction of the application with web web services and networks. This is because the programs written in it  have the ability to interact with servers and networks that provides a real time flow of information. This ability of this language has turned to be very useful or business these days. The reason for the rise of online business communities is only because of the. It has provided a boom in the eCommerce industry. It  provides the websites and applications the ability to interact with the network. This facilitates the online payments and provide the convenience to the customers.

    The technical language has established itself as one of the most favorable platforms for developing websites and software. One of the most interesting facts about this language is that the Java application development process a take place in the modules. It means that the developers can write the program in modules which can be integrated later on to create the full program. The benefit of this feature is that now if someone  wants to have a website or a program with several functionalities but  the particular programmer does not possess the necessary expertise than the whole website or  program can be broken into different modules. These modules can then be developed in different locations by different developers but can be integrated later on.

    One more benefit that this module feature provide is that the debugging can be done module wise. So when the modules are integrated later on the final program or website will be bug free. The modules are also known as Classes. These modules or classes are developed in such a way that they can be reused later on. For example if there is a travel booking website that needs to be developed so It must be having the online payment  functionality. So while writing the codes the developer develops a separate module for online payment functionality. This module then can be utilized later on if any website or program with similar functionality needs to be developed. These modules can not only be reused but can be modified according to the requirement. The codes can be extended as well as modified.

    It has one more amazing feature which is an automatic garbage collection. In this the Java developers create different objects. These objects utilizes memories during runtime as well as when they are not in use or even when their role in the program is over. So Java runtime is responsible for identifying such programs and removing them. This ability of this technology  provides access to at the memory which is otherwise not accessible by any other method. The garbage collector can run anytime but mostly it run’s when the program is ideal. The garbage collector runs itself when it analyzes that there is no free  memory to be allocated a new object. This free’s up the memory and decreases the load on the system which intern improves the computing capabilities of the system.

    It provides the safety and security feature too. It works like if anyone is transferring the Java codes from one system to other then those codes will be scanned automatically before being saved on the system to which they are being transferred to. Even if the code is saved it will never be executed if it will be having a single bug or virus. This is object oriented programming language which means the programs are written keeping objects in mind. All codes of these are written in objects and classes. It is architecture wise neutral which provides it the portability. The portability means that the program can run on any hardware or operating system. In C/C++  the portability issues arises due to fact at the source codes run in different ways because different hardware compute arithmetic calculations in different ways.

    The Java has revolutionized  the world of Information Technology by the indispensable features it provides. These features have provided the ease of programming as well as the convenience to both the developers and the end users.  It has many features that it has derived from languages like C and C++ . It does not use pointers and storage classes that add to the complexity of the program. It is therefore simple with lots of features.
