Re: [Axis2][0.95] How can my service make call to another service? (More details) - RC5

[Latha Venkat]

Hello

I have a service A that invokes service B  just by using call.invoke , after setting all the targetendpoint address , parameters and operation name .

This works fine .

 But If  I use another testclient to invoke Service A,  I'm getting an InstantiationException while trying to invoke Service A.

By using the same Test client I'm able to invoke Service B all by itself ,

 

Can anyone please help me with this ,

 

 

Thankyou

Deepal,

I've just tried it with axis2 war distribution (RC5) and got NPE.

Here is my code snippet that uses ListenerManager:

---------------------------------------------------------
System.out.println("ListenerManager.defaultConfigurationContext: " +
ListenerManager.defaultConfigurationContext);
System.out.println("ListenerManager.defaultConfigurationContext.getServiceGroupContexts():
" +
ListenerManager.defaultConfigurationContext.getServiceGroupContexts());
com.mycompany.service.test.account.AccountServicesStub stub = new
com.mycompany.service.test.account.AccountServicesStub(ListenerManager.defaultConfigurationContext,
targetEndpoint);
---------------------------------------------------------

Here is the output:

---------------------------------------------------------
ListenerManager.defaultConfigurationContext:
[EMAIL PROTECTED]
ListenerManager.defaultConfigurationContext.getServiceGroupContexts():
{}
java.lang.NullPointerException
at
org.apache.axis2.context.ServiceGroupContext.getServiceContext(ServiceGroupContext.java:59)
at
org.apache.axis2.client.ServiceClient.(ServiceClient.java:101)
at
com.mycompany.service.test.account.AccountServicesStub.(AccountServicesStub.java:329)
at
...
---------------------------------------------------------

What I've seen from the output is
ListenerManager.defaultConfigurationContext is successfully set as it's
not null. But I cannot think furthermore :-)

What should I do?

Thanks a lot.
