Load JAX-WS handler classes

A JAX-WS handler interacts with messages through a JAX-WS based v7.0 WS-Notification service point (for inbound invocation handling) or WS-Notification service (for outbound invocation handling), therefore make the handler class available to the server or cluster that hosts the WS-Notification service point or service to monitor.

This task assumes that we have already created your handler. We can do this by using IBM Rational Application Developer or a similar tool.

Before you can configure a JAX-WS handler for use with WS-Notification, make the handler class available to the server or cluster that hosts the WS-Notification service point or service to monitor.

To do this, you create a shared library for the class then add the shared library to the class loader for the server.

Procedure

1. Package the class file for your handler as a JAR file, then copy the JAR file into a convenient directory.

   Make the handler class available to the application server in one of the following ways:

   • Copy the individual class file into a directory structure under WAS_HOME/classes that matches the package name of the class, where WAS_HOME is the root directory for the installation of WAS. For example a handler class com.ibm.jaxws.handler.TestHandler is copied into the WAS_HOME/classes/com/ibm/jaxws/handler directory.
   • Package the class files for all your handlers as a JAR file, then copy it into the WAS_HOME/lib/app directory.

2. Start the administrative console.
3. Create a shared library for the JAR file.
   1. Navigate to Environment -> Shared libraries .

   2. Set the scope at which you want the new library to be visible, then click New.
   3. Give the new library a name.

   4. Set the class path to the directory and file name for your handler JAR file.

   5. Save your changes to the master configuration.

   See Create shared libraries.

4. Create a class loader for the server or cluster on which to make the JAR file available.
   1. Navigate to Servers -> Server Types -> WebSphere application servers -> server_name

      -> [Server Infrastructure] Java and Process Management -> Class loader .

   2. Click New.

   3. Click OK.

   4. Save your changes to the master configuration.

   See Configure class loaders of a server.

5. Add the shared library to the class loader for the server.
   1. Navigate to Servers -> Server Types -> WebSphere application servers -> server_name

      -> [Server Infrastructure] Java and Process Management -> Class loader -> class_loader_name > [Additional Properties] Shared library references .

   2. Click Add.

   3. Click on the name of your new library, then click OK.

   4. Save your changes to the master configuration.

   See Associate shared libraries with servers.
