Sending return value from Interceptor back to client
Hello there,
Following issue:
I've created a client that communicates with a SAP-BI Webservice. In case
that this Webservice's response doesn't seem to work with the cxf framework
I decided to program an Interceptor that intercepts the invoke() function
right after the RECEIVE state.
In it I am parsing the incoming response stream directly into one object.
My only problem here is how to return this object created in the Interceptor
back to the main()-thread. Is there any possibility to do that?
Cheers,
Chris

Hi Andrei,
FYI, I guess his requirement is from this discussion[1], obviously he don't like the solution in[1] and wanna get object from input stream directly and bypass all interceptors afterwards.

I guess you need following code to obtain MessagePart for client incoming chain:
public MessagePartInfo getClientInMessagePartInfo(Message message) {
Exchange exchange = message.getExchange();
BindingOperationInfo operation = (BindingOperationInfo)exchange.get(BindingOperationInfo.class
.getName());
if (operation == null) {
return null;
}
BindingMessageInfo bmsg = operation.getOutput();
if (bmsg == null) {
return null;
}
List<MessagePartInfo> parts = bmsg.getMessageParts();
if ((parts != null) && !parts.isEmpty()) {
return parts.iterator().next();
} else {
return null;
}
}
May I ask what exactly you update in response from SAP-BI Webservice?
Is it some payload elements and namespaces or you use own unmarshalling?
In first case CXF Transformation Feature may be helpful: http://cxf.apache.org/docs/transformationfeature.html.
Andrei.

Mhmmm...
I've tried
MessageContentsList.getContentsList(msg).put(0, response);
but function "put" has to have the parameters (MessagePartInfo, Object)...

It needs to go into the MessageContentsList of the message. Something like:
message.setContent(List.class, new Arrays.asList(response))
might also do it, but I'd recommend:
MessageContentsList.getContentsList(msg).put(0, response);

Yeah I managed adding my Response-Object to the Content of the
message-Object.
I did:
message.setContent(response.getClass(), response);
message.getInterceptorChain().doInterceptStartingAt(message, "PRE_LOGICAL");
But after that the returned Object of invoke is still null. Where is the
problem?

If you do something like:
MessageContentsList.getContentsList(msg).put(0, value);
and then likely grab the chain and pause it, it may work. If not, you may need to grab the chain and remove all the interceptors from the current interceptor up to the PRE_LOGICAL phase (and maybe more). You'd need to experiment a little on that.
