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. Modify the configuration
details for a JAX-RPC handler list that has been configured for use with service
integration bus-deployed web services.
About this task
Handlers monitor messages at ports, and take appropriate action depending upon the sender and content of each message. To enable handlers to undertake more complex operations, you chain them together into handler lists. The approach taken in WebSphere® Application Server is to apply handler lists (rather than individual handlers) at the ports, where each handler list contains one or more handlers.
To
list the existing handler lists, and to view and modify their configuration
details, use the administrative console to complete the following steps:
Procedure
- In the navigation pane, click .
- Click the name of a handler list in the list.
- Modify the following general properties:
- Name
- Modify the name of the handler list.
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 list name, the system looks up all objects that refer to it and updates the name.
- Description
- Modify the (optional) description of the handler list.
- JAX-RPC handlers
- In the JAX-RPC handlers pane, complete the following steps:
- Select one or more previously-configured handlers from either the list
of available JAX-RPC handlers or the list of handlers for this JAX-RPC handler
list, then click Add or Remove to
modify the list of handlers for this JAX-RPC handler list.
- Select a handler in the list of handlers for this JAX-RPC handler list,
then click Up or Down to change
the position of the handler within the list.
Handlers are applied in the sequence in which they appear in the handler list.
Note: If you click Reset, only the Name and Description fields
are reset to their state when the form was first loaded. The two lists of
available and assigned handlers are not reset.
- Save your changes to the master configuration.
Results
If the processing completes successfully, the list of handler lists
is redisplayed. Otherwise, an error message is displayed.
