Re: [Axis2] Invoking Interdependent Web Services in a distributed
system.
Hi Deepal
Sorry for not being very clear in previous mail.Here it is clearly.
1. Is there is a away of grouping couple of WS which serve each other in a
sever.xml which are deployed in two deterrent containers ? If that is a
single container you have the option of service group for this correct?How
do we do it for a remote invoke ?
>If you can please try to explain the question bit more clearly, so do
>you want to invoke a service (service2) from another service (service1)
>and send the final reply to the client ?
2. The above I have done. Also How wanted to know about the session
management in across web servers too in such a scenario.
Thanks
Kanchana

There should be some issues with your service (or the server). Are you
invoking in-out operation or in-only operation ?. Because read time out
indicates client can connect to the server but server does not reply,
probably your service.

Hi ,
Sorry for the late reply.
As I stated earlier, I invoke two dependent WSs. First has the second one's
business delegate (proxies ) to invoke the second.I have used axiom clients
here.At remote debugging I get the following error
org.apache.axis2.AxisFault: Read timed out

In the Second WS invoke client I have set the following .
options.setTimeOutInMilliSeconds(600000).
Your feed back highly appreciated.

Service groups cannot span across multiple Axis2 instances. I think if
you tell us more about the problem you are trying to solve rather than
explaining the solution you have in mind, we could propose a proper
solution.

HTTP session replication should be handled at the HTTP server level
and is out of the scope of Axis2. You will need to deploy Axis2 on an
HTTP server which supports clustering.
