Develop EJB implementation templates and bindings from a WSDL file

This task explains how to develop EJB implementation deployment descriptor templates and binding from a Web Services Description Language (WSDL) file.

 

Before you begin

To develop EJB implementation templates and bindings from a WSDL file, obtain the Uniform Resource Locator (URL) of the WSDL file to use.

If it is a local file and you are running the Windows platform, the URL looks like the following example: file:drive:\path\file_name.wsdl. If you are using the Linux or UNIX platform, the URL looks like the following example: file:/path/file_name.wsdl. We can also specify local files using the absolute or relative file system path.

 

Overview

This task is one a required step in developing a Web service from an enterprise bean.

Implementation templates are generated using the -role develop-server option of the WSDL2Java command.

Templates are generated for an EJB implementation for the following components:

• enterprise bean

• EJB remote interface

• EJB Home

The WSDL2Java command also generates bindings and deployment descriptors. Develop implementation templates and bindings from a WSDL file:

 

Step for this task

Run the WSDL2Java -verbose -role develop-server -container ejb wsdlURL command. Because the verbose option is specified, a list of all the generated files is displayed when the command runs.

 

Result

You have templates for the implementation and deployment descriptors required to implement Web services, as well as bindings files. These templates are partially completed with information from the WSDL file.
