A Java API for XML-based remote procedure calls (JAX-RPC) handler is a Java class that performs a range of handling tasks. For example: logging messages, or transforming their contents, or terminating an incoming request. Handlers monitor messages at ports, and take appropriate action depending upon the sender and content of each message. Modify the configuration details for a JAX-RPC handler that has been configured for use, as part of a handler list, with service integration bus-deployed Web services.
If you modify a handler class but do not change the class name, we do not have to modify the handler configuration as described in this topic. You just have to stop then restart the servers that host the ports that this handler monitors.
To list the handlers, and to view and modify their configuration details...
- Start the dmgr console.
- In the navigation pane, click Service integration -> Web services -> JAX-RPC Handlers. A list of handlers is displayed in a JAX-RPC handlers collection form.
- Click the name of a handler in the list. The current JAX-RPC handlers settings for this handler are displayed.
- Modify the following general properties:
- Name
- Modify the name of the handler.
This name must be unique, and it must obey the following syntax rules:
- It must not start with "." (a period).
- It must not start or end with a space.
- It must not contain any of the following characters: \ / , # $ @ : ; " * ? < > | = + & % '
When you change a handler name, the system looks up all objects that refer to it and updates the name.
- Description
- Modify the (optional) description of the handler.
- Class name
- Change the name of the class that is to be instantiated. If you change the class name, you must also make the new class available to the servers that host the ports that this handler monitors, as detailed in Loading JAX-RPC handler classes.
- Modify the following additional properties:
- SOAP roles
- Add, modify or remove SOAP actor definitions from the list of SOAP roles in which this handler acts. For more information, see the SOAP specification.
- JAX-RPC headers
- Add, modify or remove JAX-RPC header definitions (Namespace URI and Local part) from the list of JAX-RPC headers against which this handler operates. JAX-RPC headers are SOAP headers that are processed by a JAX-RPC handler.
- Custom properties
- Add, modify or remove custom properties (name/value pairs, where the name is a property key and the value is a string value that can be used to set internal system configuration properties).
- Save your changes to the master configuration.
Results
If the processing completes successfully, the list of handlers is redisplayed. Otherwise, an error message is displayed.
