Hi Rusda;
I am sorry for late reply.
As I can see in your service impl class, that does not have a return
value , so using /nvokeBlocking API /you are doing something wrong.
If the method does not have a return values , please dont use InOut API
, please use one way invocation like/
- fireAndForget or
-sendReboust
That will solve your problem.
Thanks
Deepal
