Assembling a Web services-enabled enterprise bean JAR file from a WSDL file

This task explains how to assemble a Web services-enabled enterprise bean JAR file from a Web Services Description Language (WSDL) file with an assembly tool.

 

Before you begin

We can assemble Web Services for J2EE modules with assembly tools provided with WebSphere Application Server.

You must configure the assembly tool before use it. You need the following artifacts to complete this task:

  • An assembled enterprise bean JAR file that contains the Enterprise JavaBeans (EJB) implementation and all classes that generate from the WSDL2Java command tool when the role argument is develop-server and the container argument is EJB.

  • A WSDL file

  • The complete webservices.xml, ibm-webservices-bnd.xmi and ibm-webservices-ext.xmi deployment descriptors, and the Java API for XML-based remote procedure call (JAX-RPC) mapping file.

 

Overview

Assemble a Web services-enabled enterprise bean JAR file from a WSDL file by following the actions in the steps for this task section.

 

Procedure

  1. Start the assembly tool. The assembly tools, Application Server Toolkit (AST) and Rational Web Developer, provide a graphical interface for developing code artifacts, assembling the code artifacts into various archives (modules) and configuring related J2EE V1.2, 1.3 or 1.4 compliant deployment descriptors.

  2. Click File > Import to import the enterprise bean JAR file into the assembly tool.

  3. Open the J2EE perspective by clicking Windows >Open Perspective > Other > J2EE.

  4. Switch to the Project Navigator pane by clicking the Project Navigator tab.

  5. Locate the project for the JAR file you just imported in the Project Navigator pane.

  6. Expand the ejbModule entry so that the META-INF directory is displayed. Expand the META-INF directory.

  7. Right-click the META-INF directory and select New > Folder. Create a subfolder named wsdl in the META-INF directory.

  8. Copy the WSDL file to the META-INF\wsdl directory by right-clicking the wsdl directory and click File > Import > File system. Browse the WSDL file for this Web service and click Finish.

  9. Copy the JAX-RPC mapping file as specified by the deployment descriptor <jaxrpc-mapping-file> element of the webservices.xml file.

  10. Copy the webservices.xml, ibm-webservices-bnd.xmi and ibm-webservices-ext.xmi deployment descriptors into the META-INF subdirectory in the same manner.

 

Result

You have the artifacts required to Web service-enable an Enterprise JavaBeans (EJB) module for Web services. The artifacts are added to the JAR file. Now we need to configure the deployment descriptors so that one can deploy the Web service into the WAS run time environment.

 

Example

After assembling the AddressBook.jar JAR filecontains

the following files after assembly. The files added in this task are in bold. These files include the WSDL file, the deployment descriptors, and the JAX-RPC mapping file 

META-INF/MANIFEST.MF 
META-INF/ejb-jar.xml 
addr/Address.class 
addr/AddressBook_RI.class 
addr/AddressBookSoapBindingImpl.class 
addr/AddressBookHome.class 
addr/Phone.class
addr/StateType.class 
addr/AddressBook.class 
META-INF/wsdl/AddressBook.wsdl
META-INF/ibm-webservices-bnd.xmi 
META-INF/ibm-webservices-ext.xmi
META-INF/webservices.xml
META-INF/AddressBook_mapping.xml

 

What to do next

Configure the webservices.xml deployment descriptor . Configure the deployment descriptors for the Web service so that WAS can process the incoming Web services requests.
