Overview of J2EE
J2EE can be expanded from Java to the Enterprise Edition, a standalone java environment used by the software or system developers to build and deploy a web-based application or a website. It is a renowned platform that uses Java programming language due to its benefits in terms of its reliability, security features, portability on cross-platform bases, easy implementation, continuously upgrading to match the latest & trending technological needs, etc.
UnderStanding to J2EE
Java programming language is always one of the best programming languages for developing a web-based application in a J2EE platform. For a long time, Java has been developed from running one small applet to a web application; now, it came to its enterprise version. This kind of enterprise web application can easily run on multiple servers and provide some enterprise-related support means it can run an application developed in EJB. This platform mainly ensures 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 to develop web applications by taking help from HTML pages or specific applet in java and defining java-based application. The main concern technologies of the J2EE platform are Servlet, and JSP (Java Server Pages), both of which 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 agendas for designing the same to run a multi-tier application designed in enterprise mode. Many popular multi-tier application server kinds of products like IBM Websphere or Weblogic are designed based on J2EE technology. Normally J2EE technology followed one common approach of accessing enterprise bean classes for getting information regarding business logic.
Advantages
Some of the key advantages are:
- It provides one of the key functionality of cross-platform portability.
- Like any other Java-based technology, open-source libraries are available easily for the common developer.
- Handling some big enterprise-level application for deploying on the server-side easily.
- Always maintained and covered the maximum global W3C Standard by J2EE technologies.
Required
Some of the key knowledge may require for understanding J2EE faster:
- 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 the web service approach in both SOAP or REST.
- Comfortable with commonly available technologies like CSS, JavaScript, HTML or JQuery.
- It Will be added additional advantage if people are comfortable with markup languages like JSON or XML.
Why should we use J2EE?
J2EE mainly helped develop any kind of web-based application by taking critical help of common HTML pages, varieties other applications, or Java applets. The two key technologies that J2EE mainly addresses are JSP (Java Server Pages) and Servlet. This is used critically in the development of any kind of enterprise-level web application.
Scope
As a Java/j2EE developer, the scope will be never-ending. There are many 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 in Java/J2EE field. So the expertise of people in this specific field always is 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 the Sun Java System application server group; it is always considered one of the Sun Java Enterprise System components. Really comfortable developers 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 develop or build one application, even including any 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 interested in learning advanced java for better utilization in the current market of their specific application.
How will this technology help you in career growth?
No doubt, learning about Java/j2EE will help any user in 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 always be in the same structure in the near future.
Conclusion
Learning about Java/J2EE is a never-ending approach. J2EE is a huge technology and always upgraded itself for better features. After learning J2EE, a 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.
