Loading JAX-RPC handler classes

A JAX-RPC handler interacts with messages as they pass into and out of the service integration bus, therefore you make the handler class available to the server or cluster that hosts the inbound or outbound port for the service that you want to monitor.

Before you begin

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

About this task

Before you can configure your JAX-RPC handler for use with service integration bus-deployed web services, you must make the handler class available. If you want to monitor an inbound port, make the handler class available to the server on which the endpoint listener for that port is located. If you want to monitor an outbound port, make the handler class available to the server on which the outbound port destination is localized.

To make the handler class available to the server or cluster that hosts the port that you want to monitor, 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 app_server_root/classes that matches the package name of the class, where app_server_root is the root directory for the installation of WebSphere® Application Server. For example a handler class com.ibm.jaxrpc.handler.TestHandler is copied into the app_server_root/classes/com/ibm/jaxrpc/handler directory.
    • Package the class files for all your handlers as a JAR file, then copy it into the app_server_root/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.

    For more information, see Creating shared libraries.

  4. Create a class loader for the server or cluster on which you want 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.
    For more information, see Configuring 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.
    For more information, see Associating shared libraries with servers.

What to do next

You are now ready to configure your handler for use (as part of a handler list) with service integration bus-enabled web services.
