JAX-WS handlers
JAX-WS handlers can be used with the web services binding.
A JAX-WS handler provides a range of handling tasks.
For example, a JAX-WS handler could log a message, or transform an incoming or outgoing message. JAX-WS handlers can be chained together to produce complex operations.
There are two types of JAX-WS handlers - logical and protocol. Logical handlers process the message payload and the properties stored in the message context. Protocol handlers operate on protocol-specific messages and message context properties. Currently, only SOAP-specific configurations are implemented.
A JAX-WS handler can be used with an export or an import.
You can create your own JAX-WS handler. If you do, the classes in your JAX-WS handler must implement the javax.xml.ws.handler.LogicalHandler or the javax.xml.ws.handler.soap.SOAPHandler interfaces. Alternately, you can choose to create a JAX-WS handler at the time you work in the properties with them. In making a selection of the handler type, one of these interfaces will be chosen.
Exports
To work with JAX-WS handlers, open the properties view of the export and click the JAX-WS handlers tab.
Follow these steps to work with the JAX-WS handlers:
- To add a JAX-WS handler, click Add in the left pane. The available handlers are listed in a handler selection window. You may also create a JAX-WS handler at this time by clicking New, selecting a handler type (SOAP or logical handler), and proceeding with the wizard to create a new JAX-WS handler.
- Select the handlers you want to consider for your binding. They are added to a list which you can order. You can also make deletions from the list.
- Once you have the handlers you want to work with, select one you want to examine for your binding and its properties are then shown on the right pane.
- Once you have made your selection of a handler for your binding and possibly updated the message context properties, save the file.
Imports
To work with JAX-WS handlers, open the properties view of the import and click the JAX-WS handlers tab.
The steps to work with and select a JAX-WS handler for your import binding are the same as an export.
