Amila, Thanks very much for the article it is a great help. I see you are the author of the article and I had a question/comment about it. It says: " Axis engine invokes in flow handlers for the given message, and at the end, it invokes the message receiver. Here, it should be noted that it is up to the message receiver XML info set is represented as an axiom object model and data binding (i.e converting xml info set to java objects and converting java objects to xml info set) is taken place at the message receiver. Finally, message receiver invokes service methods with Java objects. " Then the article a little later says: " As explained earlier axis2 data binding happens after message receiver and before the client api. "
Those two seem a little contradictory (at & after) and I was a little concerned about that because our current Axis 1.4 implementation that extends RPCProvider doesn't handle the SOAP message and just calls the underlying service. So, I turned on Axis2 debug trace and added some additional trace calls to better understand the flow and it looks, at least in this case (below), that the order is: data binding (,837), MessageReceiver (,852), service method (,915), and then the umarshalling on the out flow (,930). Does that seem right to you, or am I misunderstanding terminology, etc.? This is the trace output, which I've edited to make it more succinct: ... ,649 axiom.soap.impl.builder.StAXSOAPModelBuilder - Starting to process SOAP 1.2 message ,649 axiom.soap.impl.builder.StAXSOAPModelBuilder -

On Wed, Nov 4, 2009 at 4:43 AM, William Walsh <wwa...@curamsoftware.com<mailto:wwa...@curamsoftware.com>> wrote: Currently we use Axis 1.4 for our application and via the server_config.wsdd file (provider="java:<classname>") and extending org.apache.axis.providers.java.MsgProvider and org.apache.axis.providers.java.RPCProvider we intercept all messages and do our own routing. Obviously things are different in Axis2; but, from all the reading I've done it's not clear if we can do equivalent processing via a messageReceiver or via a Handler? We don't do any processing on the SOAP messages now, but get the method name, etc. from the MessageContext to invoke our method via reflection. If it's done via a Handler in Axis2 how do we specify the phase settings in axis2.xml to specify the last Handler and does this have to be done via a Module? (Part of my confusion comes from not finding an explanation of what RMPhase is.) Again, if it's via a Handler (as this thread suggests: http://marc.info/?t=121988146900001&r=1&w=2), I'm confused by what we would return from the Handler invoke method; that is, SUSPEND, ABORT, or CONTINUE don't seem to specify what we need to achieve, which would be more along the lines of DONE. for your case better to use a message receiver rather than a handler. this[1] may help as well. thanks, Amila.
