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 WAS. 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.

Procedure

1. Start an assembly tool. Read about starting the assembly tool in the Rational Application Developer documentation.

2. If we have not done so already, configure the assembly tool so that it works on Java EE modules. You need to make sure that the Java EE and Web categories are enabled. Read about configuring the assembly tool in the Rational Application Developer documentation.
3. 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 your 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 configure the deployment descriptors so that you 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 that you can deploy the EAR file into WAS.
