• The J2EE Developer need to create the source code in Java once.
• The code is then compiled into what is called a bytecode. It is a cross-platform intermediary and is something in between a machine language and a source code.
• After the point when the code is ready to run, the JRE or the Java Runtime Environment interprets this code and executes the same at run-time.

J2EE has always been used as an architecture framework for developing server-side deployments in Java programming language. It can be used to create software components, develop websites and at the same time create packaged applications. The platform has been worked on recently to enable it for supporting XML-based web services.

While recruiting for a J2ee Developer job, most employers prefer to appoint a candidate who has a degree in software engineering, computer science, information technology or any other connected stream. The qualification aspect may be overlooked a bit if the candidate has several years of experience in the same profile or has been involved in the development of other applications.

It is necessary to possess a proper understanding of the complete SDLC or software development life cycle if one wishes to be involved in the development of J2EE applications. This is in fact the normal procedure for application design. It is necessary to possess programming skills as well pertaining to server-side and client-side programming languages. Apart from technical knowledge, the incumbent should also possess other soft skills such as an ability to work as part of a team, analytical skills and problem solving skills.

The responsibilities of a Java developer vary from one organization to another. The J2ee Developer is given a blueprint and has to work in accordance to it in order to create web-based and server-based applications meant for both websites and computer systems. After the application has been developed, the professionals make an evaluation of the same after testing it to ensure that the application is functioning well. The developer may also be asked to participate in a session that serves to train the eventual application users.

It is quite evident that J2ee Developers can look forward to having an exciting and highflying career opportunity. Years of experience in the industry will see them making steady progress in their careers.
