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 inbound and outbound 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.
Before you begin
If you modify a handler class but do not change the class name,
you do not need to modify the handler configuration as described in this topic.
You just need to stop then restart the servers or
clusters that host the ports that this handler monitors.
Why and when to perform this task
To list the handlers, and to view and modify their configuration
details, complete the following steps:
Steps for this task
- Start the administrative console.
- In the navigation pane, click . 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: \ / , # $
@ : ; " * ? < > | = + & % '
Note: 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 or clusters 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.
If the processing completes successfully, the list of handlers is
redisplayed. Otherwise, an error message is displayed.
