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

We can assemble a web services-enabled enterprise bean JAR file from a WSDL file with an assembly tool.

We can assemble Java-based web services modules with assembly tools provided with WebSphere Application Server. You need the following artifacts to complete this task:

• An assembled enterprise bean JAR file containing the EJB implementation and all classes that generate from the WSDL2Java command-line 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.

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

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 verify 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 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 runtime 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/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

For JAX-RPC web services, configure webservices.xml . You need to configure the deployment descriptors for the web service so that WAS can process the incoming web services requests.
