Configure the webservices.xml deployment descriptor for handler classes

 

This topic explains how to use and assembly tool to configure the webservices.xml deployment descriptor for user-provided handler classes.

You can configure deployment descriptors with assembly tools provided with WAS.

A handler class is a class that is written to modify a SOAP message that represents a remote procedure call (RPC) request or response. Handlers can be associated with a Web service or a Web service client.

To complete this task, we need an enterprise archive (EAR) file for the applications to configure. For some handler use, such as logging or tracing, only the server or client application require configuration. For other handler use, including sending information in the SOAP headers, the client and server applications must be configured with symmetrical handlers.

The modules in the EAR file contain the handler classes to configure. These classes implement the javax.xml.rpc.handler.Handler interface. For more information on writing handler classes, see Chapter 6 of the Web Services for J2EE specification and Chapter 12 of the JAX-RPC specification available through Web services: Resources for learning. The application modules must contain the webservices.xml deployment descriptor.

 

Overview

Configure a handler in the webservices.xml deployment descriptor by following the listed steps:

 

Procedure

  1. Start an assembly tool. See "Starting WAS Toolkit" in the Application Server Toolkit documentation for more information.

  2. If you have not done so already, configure the assembly tool to work on J2EE modules. Verify the J2EE and Web categories are enabled. See "Configuring WAS Toolkit" in the Application Server Toolkit documentation for more information.

  3. Migrate the WAR files that are created with the Assembly Toolkit, Application Assembly Tool (AAT) or a different tool to an AST or assembly tools. To migrate files, import your WAR files to the assembly tool. See "Importing WAR files" in the Application Server Toolkit documentation for more information.

  4. Configure the client deployment descriptor. See "Editing Web services" in the Application Server Toolkit documentation for more information.
