[Axis2] does client need to know MEP?
Hi all,
I was writing my client without using the generated stub (but mimicking
what the stub does). I saw that the generated stub creates different kinds
of operations OutInAxisOperation, InOnlyAxisOpeepending on how the message
exchange pattern of the operation is on the sever side.
But how does a client discover an MEP for a service operation? It is not in
WSDL.
So my question is, is it necessary to create the right kind of operation
to correctly invoke the service or it is optional?
Thanks,
-Nirmit

I have not see Erans answer so I cannot comment on the accuracy of the solution
If you look at the Axis source DescriptionBuilder.java you will see a method called processActionMapping
The mappingIterator will construct itself and iterate on elements based on the existence of "actionMapping" in services.xml
Does this answer your question ?

Hi Martin,
Thanks for the info. What you describe happens at the service side. My
concern is whether the client needs to be aware about the MEP of the
operation it is invoking.
Eran answered my questions and I need not use specialized operation client.
Still, I have to figure out the MEP of the operation by parsing WSDL and
looking at whethyer the operation has both input and out or just the input.
I am wondering if tthere is any easier way for a client to know the MEP.
Thanks

The answer is the MEP of an Operation is determined from the Java Method
specifically..
All the public methods in the service implementation class are exposed
(whether you specified that in services.xml or not.)
Axis2 calculates the MEP of an operation by checking its corresponding java
method.
If the method is void, the MEP will be in-only;
else, it will be in-out,
(depending on which MEP message receiver will be set.)

If you wanna touch message context, if you wanna touch the sending SOAP
message to customize a lot.

Yep. ServiceClient is ideal for you.

For IN only :
- sendRobust
- fireAndForget are fine
For IN-OUT
- sendReceive is fine for a blocking invocation.

Hi Eran,
Thanks for the clarification. However, what do you mean by simple stuff?
Can you point me to the situations that demand such specialized operations?
or the use of operation clients? I am interested in knowing:
--whether ServiceClient is good enough for invoking doc/lit services,
taking one message part at the most, and with in-only or in-out MEPs? The
soapAction would be set in the Options. If so I would like to stick to the
ServiceClient usage.
--If ServiceClient can indeed handle the above, and blocking invocations
are fine, I should use fireAndForget() for in-only MEP and sendReceive()
for in-out MEP. Is that right?
Thanks a lot, I appreciate your help,
-Nirmit

MEP can always be deduced by the WSDL. Just look at the messages for an
operation. If you have
one input and one output - IN-OUT
one input - IN-Only.
Just identify the MEP and invoke either sendReceive or send depending on
that. No you don't need to juggle with OutInAxisOperation,
InOnlyAxisOperations if you are doing somple stuff.
