Develop EJB implementation templates and bindings from a WSDL file
You can develop EJB implementation deployment descriptor templates and bindings from a Web Services Description Language (WSDL) file for a JAX-RPC application. To develop EJB implementation templates and bindings from a WSDL file for a Java API for XML-based RPC (JAX-RPC) Web service, obtain the Uniform Resource Locator (URL) of the WSDL file to use.

If the WSDL file is a local file, the URL looks like the following example: file:drive:\path\file_name.wsdl.

![[HP-UX]](../../hpux.gif)

If the WSDL file is a local file, the URL looks like the following example: file:/path/file_name.wsdl.
You 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:
Procedure
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.
Results
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.
Example
The following example uses the enterprise bean AddressBook enterprise bean and the AddressBook.wsdl file. After generating the template files from the WSDL2Java -verbose -role develop-server -container EJB AddressBook.wsdl command, the following files are generated:Parsing XML file: file:e:/example/app/topdown/step1/AddressBook.wsdl WSWS3185I: Info: Parsing XML file: AddressBook.wsdl WSWS3282I: Info: Generating addr\Address.java. WSWS3282I: Info: Generating addr\Phone.java. WSWS3282I: Info: Generating addr\StateType.java. WSWS3282I: Info: Generating addr\AddressBook.java. WSWS3282I: Info: Generating addr\AddressBookSoapBindingImpl.java. WSWS3282I: Info: Generating addr\AddressBook_RI.java. WSWS3282I: Info: Generating addr\AddressBookHome.java. WSWS3282I: Info: Generating META-INF\webservices.xml. WSWS3282I: Info: Generating META-INF\ibm-webservices-bnd.xmi. WSWS3282I: Info: Generating META-INF\AddressBook_mapping.xml. WSWS3282I: Info: Generating META-INF\ibm-webservices-ext.xmi.
What to do next
Complete the EJB implementation. When you complete the EJB implementation, an EJB Java archive (JAR) file that contains an EJB and supporting classes is created from a WSDL file.Completing the EJB implementation
