Completing the EJB implementation

 

This task explains how to complete the EJB implementation. Develop EJB implementation templates and bindings from a WSDL file. The deployment descriptor templates that are generated from a Web Services Description Language (WSDL) file are required to complete the EJB implementation in the Web services development process.

 

Overview

When you complete the EJB implementation, you are assembling an enterprise bean Java archive (JAR) file that contains the EJB and supporting classes created from a WSDL file. Complete the EJB implementation by following the steps provided in this task section.

 

Procedure

  1. Inspect the EJB remote interface template, portType_RI.java. If necessary, modify the template. The value portType is the name of the <wsdl:portType> element in the WSDL file.

  2. Inspect the portTypeHome.java EJB home interface template. If necessary, modify the template.

  3. Edit the bindingImpl.java EJB implementation template. Where binding is the name of the <wsdl:binding> element in the WSDL file.

    1. Complete the implementation of the methods in the template.

    2. (Optional) Make changes if necessary.

    3. (Optional) Change the class name if the binding name is not acceptable.

  4. Compile all the Java classes.

  5. Assemble an EJB Java archive (JAR) file. Assemble all the Java classes into an enterprise bean JAR file using the typical EJB assembly tools. Include all of the classes generated from running the WSDL2Java command tool when developing implementation templates and bindings from a WSDL file.

 

Results

You have an enterprise bean JAR file containing an EJB and supporting classes created from a WSDL file.
