I have an existing application (say 'A') and I want to call a java function of this app from another app 'B'.
I don't want to put dependency of this app('A') in my calling application('B') to avoid running 'A' at multiple places.
We thought of exposing 'A's function as a web service, which can be called by 'B' by putting dependency on the 'A's client.
What is the efficient and easy way to do this.
Thanks in advance.
Depending on the type of service:
Either way, you put a couple of annotations on your class, and configure the framework to expose the service (refer to the documentation of whichever you choose)
