Hi,
Given what you need to do (which is possible ofcourse) it simply
requires a bit more knowledge about the internals of Axis2. I am going
to outline a doable procedure but unfortunatley I don't have the time
to write a lengthy description and elaborate each point.
1. You need to introduce a custom dispatcher (Axis does not enforce
the action but it comes addressing enabled by default). What this
dispatcher does is figuring out the static and runtime service and
operation 'data bags'. We call them AxisService,AxisOperation and
serviceContext, operationContext. Ultimately your custom dispatcher
should provide the these 'data bags' relevant to your service. Please
have a look at the dispatcher implementations to get an idea of how
these work.
2. Write a custom message receiver. If you generate code for server
side using a simple WSDL you will see the source for a custom message
receiver. Modify the code off that not to find the method using the
action.
That should do it :)

I'm still trying to figure out how to deploy a message style service

Axis to figure out what method to invoke. There's only one method
available.
I tried the 1st possible solution mentioned below,
"1. Remove the dispach phase from your Axis2 configuration and write
your own MessageReceiver (which removes the need for an AxisOperation
to be identified)"
I wrote a new message receiver but ran into bigger problems. If I remove
the <actionMapping> tags in the service's deployment descriptor, my new
message receiver never gets called. I receive a fault with a response code
500 with no additional information to help diagnose where the problem
occured. Nothing showed up in Tomcat's catalina.log.
Same problem seems to occur if the wsa:Action header value in the request
doesn't match the set of <actionMapping> tags for the service.
I tried commenting out the dispatch phase as stated as a suggestion without
any difference in behavior.
Suggestions? Is there an easier way to accomplish this? It still appears to
me to be an Axis design issue. Axis should not force declaration of
specific wsa:Action values for a message based service. It could be an
option, but should not be required. Wildcard or similar should be
supported.

declare <actionMapping> values in the service deployment descriptor. In
case you're wondering, this service also dynamically generates WSDL to
describe the discovered supported operations.

What you are trying to do sounds pretty advanced (given that you're
dynamically generating WSDL).
There are a couple of options I can think of...
1. Remove the dispach phase from your Axis2 configuration and write
your own MessageReceiver (which removes the need for an AxisOperation
to be identified)
2. Define a single operation for the service and add a handler to the
DispatchPhase which selects that operation when the
RawXMLInOutReceiver will then invoke on the endpoint object.
