Assembling a JAR file that is enabled for Web services from an enterprise bean
This topic explains how to assemble a Web service-enabled enterprise bean Java archive (JAR) file with an assembly tool.
You can assemble Java-based Web services modules with assembly tools provided with WAS. We need the following artifacts that are generated from the WSDL2Java command-line tool to complete this task:
- An assembled enterprise bean JAR file that is not enabled for Web services
- A compiled Java class for the service endpoint interface
- A Web Services Description Language (WSDL) file
- The complete webservices.xml,ibm-webservices-bnd.xmi, and ibm-webservices-ext.xmi deployment descriptor, and Java API for XML-based remote procedure call (JAX-RPC) mapping file.
Overview
Assemble a Web services-enabled enterprise bean JAR file from Java code by following the actions in the steps for this task section.
Procedure
- Start an assembly tool. See "Starting WAS Toolkit" in the Application Server Toolkit documentation for more information.
- If you have not done so already, configure the assembly tool so that it works on J2EE modules. We need to make sure that the J2EE and Web categories are enabled. See "Configuring WAS Toolkit" in the Application Server Toolkit documentation for more information.
- Migrate JAR files created with the Assembly Toolkit, Application Assembly Tool (AAT) or a different tool to an AST or Rational Application Developer assembly tool. To migrate files, import your JAR files to the assembly tool. See "Migrating code artifacts to an assembly tool" in the Application Server Toolkit documentation.
Results
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 configure the deployment descriptors so that you can deploy the Web service into the WAS run time environment.
Example
The AddressBook.jar JAR file contains 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/AddressBookBean.class addr/AddressBookHome.class addr/Phone.class addr/StateType.classaddr/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
Assemble the EAR file so that you can deploy the EAR file into WebSphere Application Server.
