Assembling a WAR file that is enabled for web services from Java code
We can assemble a WAR file that is enabled for web services from Java code with an assembly tool.
We can assemble Java-based web services modules with assembly tools provided with WAS.
For JAX-WS web service applications, you need the portable artifacts that are generated by the wsgen command-line tool when starting from a service endpoint implementation to complete this task. The wsgen tool processes a compiled service endpoint implementation class as input and generates the following portable artifacts:
- any additional Java Architecture for XML Binding (JAXB) classes that are required to marshal and unmarshal the message contents. The additional classes include classes that are represented by the @RequestWrapper annotation and the @ResponseWrapper annotation for a wrapped method.
- a WSDL file if the optional -wsdl argument is specified. The wsgen command does not automatically generate the WSDL file. The WSDL file is automatically generated when you deploy the service endpoint.
For JAX-RPC web service applications, you need the following artifacts that are generated by the WSDL2Java command-line tool to complete this task:
- An assembled WAR file that contains the web.xml file, but is not enabled for web services.
- The Java class for the service endpoint interface
- 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 classes that are generated by the WSDL2Java command.
Assemble a web services-enabled WAR file from Java code by following the actions in the steps for this task section.
Procedure
- 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 make sure that the Java EE and Web categories are enabled. Read about configuring the assembly tool in the Rational Application Developer documentation.
- Import the JavaBeans implementation and the artifacts generated by the command-line tooling into the assembly tool.
- Migrate WAR files created with the Assembly Toolkit, Application Assembly Tool (AAT) or a different tool to the Rational Application Developer assembly tool.
To migrate files, import your WAR files to the assembly tool. Read about migrating code artifacts to an assembly tool in the Rational Application Developer information.
Results
The artifacts required to enable the web module for web services are added to the WAR file.
What to do next
Now you can assemble the WAR file that is enabled for Web services into an EAR file.To learn more, read about assembling a web services-enabled WAR into an EAR file.
