Interceptor: How to verify the current context (inbound/outbound and request/response)

Hi there

I can check whether handleMessage is called in the context of inbound or outbound with the following lines:

boolean isOutbound = message == message.getExchange().getOutMessage()
               || message == message.getExchange().getOutFaultMessage();

But how can I check whether it's outbound in the context before the request is sent or a response is sent?

Thanks
Oliver

Hi Eoghan

I was exactly looking for that.

Thanks

Oli,

The outMessage in this case is the outbound message currently being 
marshalled up *before* being sent. So your code will work before the 
request/response is sent.

For example on the client-side, ClientImpl.invoke() delegates to the 
binding to create the outMessage and sets this on the Exchange before 
traversing the intercpetor chain.

In fact, this sort of test is pretty much the approach used by the WS-A 
code to determine message direction (with a little added defensiveness 
against NPEs). See ContextUtils.isOutbound():
