Technical Java Sample Questions : J2EE Sample Questions

  1. What is the J2EE 1.4 SDK?

    Answer: The Java 2 SDK, Enterprise Edition 1.4 (J2EE 1.4 SDK) is a complete package for developing and deploying J2EE 1.4 applications.The J2EE 1.4 SDK contains the Sun Java System Application Server Platform Edition 8, the J2SE 1.4.2 SDK, J2EE 1.4 platform API documentation, and a slew of samples to help developers learn about the J2EE platform and technologies and prototype J2EE applications.The J2EE 1.4 SDK is free for both development and deployment.

  2. Which version of the platform should I use now -- 1.4 or 1.3?

    Answer: The J2EE 1.4 specification is final and you can use the J2EE 1.4 SDK to deploy applications today.However, for improved reliability,scability, and performance, it is recommended that you deploy your applications on J2EE 1.4 commercial implementations that will be available early in 2004.If you want to deploy your application before 2004, and reliability,scability, and performance are critical, you should consider using a high performance application server that supports J2EE v1.3 such as the Sun Java System Application Server 7.Many application server vendors are expected to release J2EE platform v1.4 versions of their product before the spring.

  3. Can applications written for the J2EE platform v1.3 run in a J2EE platform v1.4 implementation?

    Answer: J2EE applications that are written to the J2EE 1.3 specification will run in a J2EE 1.4 implementation.Backwards compatibility is a requirement of the specification.

  4. How is the J2EE architecture and the Sun Java Enterprise System related?

    Answer: The J2EE architecture is the foundation of the Sun Java System Application Server, a component of the Sun Java Enterprise System.The Sun Java System Application Server in the current Sun Java Enterprise System is based on the J2EE platform v1.3, with additional support for Web services.Developers familiar with J2EE technology can easily apply their skills to building applications, including Web services applications, using the Sun Java Enterprise System.For more information, see the Sun Java Enterprise System Web site.

  5. Can I get the source for the Sun Java System Application Server?

    Answer: You can get the source for the J2EE 1.4.1 Reference Implementation from the Sun Community Source Licensing site.The J2EE 1.4.1 Reference Implementation is the Sun Java System Application Server Platform Edition 8 minus the following components:

    • The installer
    • The Web-based administration GUI
    • JavaServer Faces 1.0 and JSTL 1.1
    • Solaris specific enhancements for security and logging
    • Higher performance message queue implementation

  6. Who needs the J2EE platform?

    Answer: ISVs need the J2EE platform because it gives them a blueprint for providing a complete enterprise computing solution on the Java platform.Enterprise developers need J2EE because writing distributed business applications is hard, and they need a high-productivity solution that allows them to focus only on writing their business logic and having a full range of enterprise-class services to rely on, like transactional distributed objects, message oriented middleware, and naming and directory services.

  7. Are there compatibility tests for the J2EE platform?

    Answer: Yes.The J2EE Compatibility Test Suite (CTS) is available for the J2EE platform.The J2EE CTS contains over 5,000 tests for J2EE 1.4 and will contain more for later versions.This test suite tests compatibility by performing specific application functions and checking results.For example, to test the JDBC call to insert a row in a database, an EJB component makes a call to insert a row and then a call is made to check that the row was inserted.

  8. What is the difference between being a J2EE licensee and being J2EE compatible?

    Answer: A J2EE licensee has signed a commercial distribution license for J2EE.That means the licensee has the compatibility tests and has made a commitment to compatibility.It does not mean the licensees products are necessarily compatible yet.Look for the J2EE brand which signifies that the specific branded product has passed the Compatibility Test Suite (CTS) and is compatible.

  9. What is the web container?

    Answer: Servlet and JSP containers are collectively referred to as Web containers. It manages the execution of JSP page and servlet components for J2EE applications. Web components and their container run on the J2EE server.

  10. What is Enterprise JavaBeans (EJB) container?

    Answer: It manages the execution of enterprise beans for J2EE applications. Enterprise beans and their container run on the J2EE server.
