BTW you can do the above like this...
public class MyBean {
@Consume(uri="activemq:SomeQueue")
pubilc void onXml(@XPath("/foo/ID") String myID, Document restOfBody) {
// return the transformed payload
return "MATCHED=TRUE"
}
}
Notice Camel can do the XPath for you and inject the ID parameter to
your transformer method (myID) - also notice the lack of any
middleware APIs etc.
