Java is both a language as well as operating platform. Java itself is categorized into three different groups namely core java, advanced java and J2EE java. Out of these 3 categories of java, core java and advanced version of java comes under Java standard edition while the J2EE version comes under enterprise edition.
J2EE (Java 2 enterprise edition) is a platform for running programming server of Java language. Java enterprise edition has many extra attractive features in comparison to Java standard edition, thus demand for J2EE platform is increasing in the market. Today IT geeks, java developers, software industry prefer J2EE platform, thus demand for J2EE experts in the market has increased. During technical interview, you would surely come across J2ee interview questions. So if you are going to appear for Java developer and related job post and are looking for some J2ee interview questions, then do go through some of these basic J2ee interview questions.
1. What is J2EE?
This question could be asked in different way like briefly describe history of J2EE, what is the objective of J2EE, why we need J2ee. While answering this question be precise & do not delve into long answer, as interviewer is just looking for your research capability and basic knowledge about J2EE platform.
2. What is JDBC?
Here recruiter may ask you questions on JDBC (java database connectivity) related to types of JDBC drivers available in the market, connection mechanism of JDBC drivers viz. pooling of JDBC connection, accessing and creating JDBC connection.
3. What is Java servlets and types of different Java servlets API released by Sun Microsystems and their features.
Java servlets uses software development life cycle (SDLC) concept to develop application on J2EE platform. So while appearing for J2ee interview questions round, you may be asked various questions on Java servlets domain like servlets lifecycle feature, need of servlets, java servlets working mechanism etc. Every Java servlets is associated with Java API’s for application development and according to data execution different types of API’s is being used with Java servlets.
4. What is JSP?
JSP i.e. java server pages have different important features like scripting elements, page directives, java beans element, tagging and creating of customs and different JSP patterns. Make notes on all these concepts related to java server pages to customize your knowledge on JSP.

Besides preparing for all these J2ee interview questions, also make sure to practice some program related to J2EE platform development and testing. During your interview you would be asked both theoretical and programming based question. So if you haven’t prepared the J2EE programming part then it would be difficult to convert your interview call, as Java developer/operator post requires excellent knowledge about J2ee programming. Thus, prepare well both the given J2ee interview questions here as well as practice J2EE programming and achieve success in Java technical interview round.
