Axis1 style="message" in Axis2?
I need to implement a message style web service in Axis2. In Axis1 wsdd,
this would be a web service declared with
<service name=xxx style="message">
How do I declare the equivalent web service in Axis2? In addition, I will
expect that WS-Addressing headers will be sent and received. From reading
the Axis2 documentation, it looks like the <actionMapping> element is used
to map an action header value to an operation name. In my case I want
Axis2 to always send me the body of the message. I do not want Axis2 to
try and determine which operation is being invoked, I want it to send the
message to a specific method all the time, as a message style service did
in Axis1.
I'm doing this because my service is mapping web service invocations of
operations to another form of invocation on non-Java objects.
Thanks

Can you clarify what Axis is generating an error if <actionMapping> is not
specified? I had commented out the dispatch phase from axis2.xml and it was
still returning a 500. Where is the exception being logged?
I'd like to have more confidence in the solution before investing too much
time in it.

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 :)

Re: Axis1 style="message" in Axis2?
Posted by David Melgar <dm...@us.ibm.com>.
I'm still trying to figure out how to deploy a message style service
WITHOUT having to declare each possible wsa:Action value which might be
used on the invocation. Its a message style service... I dont want or need
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.

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.

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

RE: Axis1 style="message" in Axis2?
Posted by "Bhatra, Junaid" <jb...@rsasecurity.com>.
I ran into the same problem some time back in which I wanted Axis 1.x
"message" style behavior in Axis 2 in order to dispatch to non-standard
Java objects. I ended up using a work-around involving SOAPAction since
Axis 2 contains an action-based dispatcher. So every operation defined
in my WSDL specified the same SOAPAction value equal to my service
method name. I was using RawXMLMessageReceiver with a single method.
Note that I was using WSDL 1.1/SOAP 1.1. I haven't tried this with SOAP
1.2/WSDL 2.0, which does not have SOAPAction, although it does make use
of an action parameter with exactly the same semantics. I'm guessing you
could do the same using wsa:Action header as well.
It would definitely be nice though to have a wildcard <actionMapping>
with Axis 1.x "message" style semantics instead of having to work-around
this problem.

Setting the message receiver to RawXMLMessageReceiver still appears to
require <actionMapping> to determine which method to invoke. In axis1,
the specified method would receive all messages for that service.
Equivalent behavior should be available in axis2 regardless of the value
of the wsa:Action header.
To further clarrify, the service I'm writing bridges between webservices
and a non-Java object invocation mechanism. It dynamically determines
what operations are allowed. This services does not know at deployment
time what operations are possible. I therefore don't know all the
wsa:Action header values that it might be included in request messages.
Therefore I cannot 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.
Is there a way to wildcard <actionMapping> to say that any action maps
to a method? Or to avoid the requirement for specifying an actionMapping
if RawXMLMessageReceiver is used.
Are there other approaches that could be used?
