Method Detail

handleRequest

public boolean handleRequest(javax.xml.rpc.handler.MessageContext msgContext)

Gets the RPCInvocation before the the server handler chain is invoked, gets it again after handler processing and replaces it in the message contaxt in case the handlers modified the request SOAPEnvelope.

Specified by:: handleRequest in interface javax.xml.rpc.handler.HandlerChain
Overrides:: handleRequest in class HandlerChainBaseImpl

Parameters:: msgContext - MessageContext parameter provides access to the request SOAP message.
Returns:: Returns true if all handlers in chain have been processed. Returns false if a handler in the chain returned false from its handleRequest method.

handleResponse

public boolean handleResponse(javax.xml.rpc.handler.MessageContext msgContext)

Initiates the response processing for this handler chain.

In this implementation, the response handler chain starts processing from the same Handler instance (that returned false) and goes backward in the execution sequence.

Specified by:: handleResponse in interface javax.xml.rpc.handler.HandlerChain
Overrides:: handleResponse in class HandlerChainBaseImpl

Returns:: Returns true if all handlers in chain have been processed. Returns false if a handler in the chain returned false from its handleResponse method.
Throws:: javax.xml.rpc.JAXRPCException - if any processing error happens
