public boolean <B>handleRequest</B>(<A HREF="../../../../javax/xml/rpc/handler/MessageContext.html" title="interface in javax.xml.rpc.handler">MessageContext</A>&nbsp;context)</PRE>
<DL>
<DD>The <code>handleRequest</code> method processes the request 
  SOAP message. The default implementation of this method returns 
  <code>true</code>. This indicates that the handler chain
  should continue processing of the request SOAP message.
  This method should be overridden if the derived Handler class
  needs to specialize implementation of this method.

<DT><B>Parameters:</B><DD><CODE>context</CODE> - <code>MessageContext</code> parameter provides

                 <LI>Return <code>true</code> to indicate continued 
                     processing of the request handler chain. The 
                     <code>HandlerChain</code>
                     takes the responsibility of invoking the next 
                     entity. The next entity may be the next handler 
                     in the <code>HandlerChain</code> or if this 
                     handler is the last handler in the chain, the 
                     next entity is the service endpoint object.
                 <LI>Return <code>false</code> to indicate blocking 
                     of the request handler chain. In this case, 
                     further processing of the request handler chain
                     is blocked and the target service endpoint is 
                     not dispatched. The JAX-RPC runtime system takes
                     the responsibility of invoking the response 
                     handler chain next with the SOAPMessageContext. 
                     The Handler implementation class has the the 
                     responsibility of setting the appropriate response
                     SOAP message in either handleRequest and/or 
                     handleResponse method. In the default processing
                     model, the response handler chain starts processing
                     from the same Handler instance (that returned false)
                     and goes backward in the execution sequence.
