43.2. Implementing a Logical Handler

Overview

Logical handlers implement the javax.xml.ws.handler.LogicalHandler interface. The LogicalHandler interface, shown in Example 43.1, “LogicalHandler Synopsis” passes a LogicalMessageContext object to the handleMessage() method and the handleFault() method. The context object provides access to the body of the message and to any properties set into the message exchange's context.

Example 43.1. LogicalHandler Synopsis

public interface LogicalHandler extends Handler
{
  boolean handleMessage(LogicalMessageContext context);
  boolean handleFault(LogicalMessageContext context);
  void close(LogicalMessageContext context);
}

Procedure

To implement a logical hander you do the following:
  1. Implement any initialization logic required by the handler.
  2. Implement the message handling logic.
  3. Implement the fault handling logic.
  4. Implement the logic for closing the handler when it is finished.
  5. Implement any logic for cleaning up the handler's resources before it is destroyed.
