Assembling a JAR file that is enabled for web services from an enterprise bean
We can assemble a web service-enabled enterprise bean JAR file with an assembly tool using artifacts generated from tooling.
We can assemble Java-based web services modules with assembly tools provided with WebSphere Application Server. You 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 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.
Assemble a web services-enabled enterprise bean JAR file from Java code by following the actions in the steps for this task section.
- Start an assembly tool. Read about starting the assembly tool in the Rational Application Developer documentation.
- If we have not done so already, configure the assembly tool so that it works on Java EE modules. You need to verify the Java EE and Web categories are enabled. Read about configuring the assembly tool in the Rational Application Developer documentation.
- Migrate JAR files created with the Assembly Toolkit, Application Assembly Tool or a different tool to the Rational Application Developer assembly tool. To migrate files, import the JAR files to the assembly tool. Read about migrating code artifacts to an assembly tool in the Rational Application Developer documentation.
Results
You have the artifacts required to web service-enable an EJB module for web services. The artifacts are added to the JAR file. Now we need to configure the deployment descriptors so we can deploy the web service into the application server 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.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
Assemble the EAR file so we can deploy the EAR file into WebSphere Application Server.
