Hi All,
In my BE component, I need to call some admin services to through stub and
I want to use local transport for that.
For that, I changed the service url to "local://services/DashboardService"
in order to communicate with admin service 'DashboardService', and passed
the configuration context which is obtained from
ConfigurationContextService - OSGI declarative service.
But I'm getting the following exception when I try to invoke a method from
the stub.
java.lang.NullPointerException

I debug and checked in the axis2, and seems the error NPE is because of
transportIn is being null in the messageContext and the line which throws
the exception is,
TransportListener listener = msgContext.getTransportIn().getReceiver();
How this should be done? Is there any additional configuration that I need
to add for this?
Any help is appreciated.
Thanks,
Sinthuja.
