Overview of J2EE
J2EE stands for Java to the enterprise edition. This is basically one of the independent platform and purely java based environment providing by Sun. This environment mainly helps the developer for building, developing or deploying any kind of web-based application which will be available online. This platform specifically contains some of the critical set of services, popular APIS, and some define protocols that mainly ensures of developing a web-based application in a multi-tier approach. It is one of the critical Java platforms where all kinds of enterprise web applications will run properly and provide an environment to the developer for development, building or deploying their own enterprise application successfully.
UnderStanding to J2EE
Java programming language is always one of the best programming languages for developing a web-based application in a J2EE platform. Considering a long period of time Java has been developed from running one small applet to a web application, now it came to the enterprise version of the web application. This kind of enterprise web application can run on multiple servers easily, provide some enterprise related support means it can able to run an application which is developed in EJB. This platform is mainly ensuring of building some kind of web application that can define as a server-side application. It is following one architecture of providing the required infrastructure through varieties set of developed services.
How does J2EE make working so easy?
It normally provides some critical business enterprise web application very easily. It comes with one of the great platforms to the developer for developing their web application and deploying the same in a specific platform. J2EE normally holds varieties of API that always create one helpful environment to build a difficult enterprise system. Whereas this can be considered as half of the picture of entire J2EE features. J2EE is also one of the standard edition for developing and building or deploying any kind of enterprise application working together by some of the required specifications of API which is defined properly and require services also can be provided by J2EE.
What can you do with J2EE?
It is mainly used for developing any kind of web application by taken help from HTML pages or specific applet in java and define java based application. The main concern technologies of the J2EE platform are Servlet and JSP (Java Server Pages), both of them are very much useful normally in an enterprise web application. J2EE is mainly used for developing any kind of enterprise level web application.
Working with J2EE
This is mainly developed and run in Java Platform, one of the main agenda for designing the same to run a multi-tier application which is designed in enterprise mode. There has a lot of popular multi-tier application server kind of product like IBM Websphere or Weblogic has been designed based on J2EE technology. Normally J2EE technology followed one common approach of accessing enterprise bean classes for getting information regarding business logic.
Some of the key advantages are:
- Provides one of the key functionality of cross-platform portability.
- As like any other Java-based technology, open source libraries are available easily for the common developer.
- Handling some big enterprise level application for deploying in server side easily.
- Always maintained and covered the maximum global W3C Standard by J2EE technologies.
Some of the key knowledge may require for understanding J2EE faster:
4.5 (1,977 ratings)
- Have some key knowledge on specifically in Servlet and JSP view.
- Comfortable on any web framework specifically on Struts or Spring.
- Comfortable or clear understanding require in a service-oriented architecture.
- Comfortable and clear understanding require in web service approach in both SOAP or REST.
- Will be added additional advantage if people are comfortable on markup languages like JSON or XML.
Why should we use J2EE?
J2EE is mainly helped for developing any kind of web-based application by taken critical help of common HTML pages, varieties other applications, or Java applets. The two key technologies which are mainly addressed by J2EE are JSP (Java Server Pages) and Servlet. This is used critically in the development of any kind of enterprise level web application.
As a Java/j2EE developer scope will be never-ending. There has a lot of opportunities available in the current market for specific expertise level required in the Java/J2EE field. For any kind of available popular tool, java/j2EE experts people are always welcome to introduce those tools. As of now maximum organization or maximum opening in the current IT market are specifically on Java/J2EE field. So expertise people of this specific field always be valuable in any kind of situation. At least one job always be in their hand without any exception.
Why do we need J2EE?
This architecture is one of the popular architecture available in the current industry. This is founded by Sun Java System application server group, it always is considered as one of the components of the Sun Java Enterprise System. Developers who are really comfortable and experts in Java/J2EE technologies there have a lot of opportunities for applying their skills in the current industry. Any J2EE developer can easily able to develop or build one application even including any kind of web or web service related application commonly using the sun java enterprise system technologies.
Who is the right audience for learning J2EE technologies?
The target audience can be any core java experts people, interesting to learn advance java for better utilization in the current market of their specific application.
How this technology will help you in career growth?
There was no doubt that learning about Java/j2EE will be of great help for any user on their career development. J2EE expert peoples are always welcome in the critical organization. Maximum opening in the current IT industry still in Java/J2EE and it will be always in the same structure in the near future.
Learning about Java/J2EE is never ending approach. J2EE is a huge technology and always upgraded itself for better features. After learning J2EE developer should need to concentrate more on some specific framework like Spring core, Spring MVC, Spring Boot or Struts 1, 2, etc. Those are very much urgent for always developing your skill specifically in J2EE technologies.
