Develop a WSDL file

You need a WSDL file to use Web services. You can develop your own WSDL file or get one from a Web service provider through E-mail, downloading or through a Uniform Resource Locator (URL). This documentation assumes you are creating your own.

To develop a WSDL file, follow these steps:

  1. Run the Java2WSDL seiInterface command.

    • Move the WSDL file to the META-INF/wsdl subdirectory if you are using enterprise JavaBeans (EJB).
    • Move the WSDL file to the WEB-INF/wsdl subdirectory if you are using a Java bean.

    A WSDL file named seiInterface.wsdl is created.

  2. Edit the generated WSDL file and inspect the part names.
    The WSDL parts have names like arg_0_0. Modify the WSDL file to use the actual names of the Java parameters.

  3. (Optional) Use the Java2WSDL command tool to generate the correct part names of WSDL file.
    You can automatically generate and set the correct part names by using the Java2WSDL command tool. Generating and setting the part names is done by providing additional information to the Java2WSDL command in the form of a Java implementation class that implements the same methods as the Service Endpoint Interface and is compiled with debug information on (javac -g). Parameter names are stored in the .class file with the debug information. If your implementation class was compiled with debug on, you can use the Java2WSDL -implClass seiImpl seiInterface command to generate a WSDL file having the proper part names.

Example

This example uses a JAR file named AddressBook.jar containing a class named AddressBook.class file.

You must add the AddressBook.jar file to your CLASSPATH to create the WSDL file. The JAR file contains an enterprise JavaBean (EJB) implementation class that was compiled with debugging information on. Run the Java2WSDL -implClass addr.AddressBookBean addr.AddressBook command to create a WSDL file named AddressBook.wsdl.
