How to throw User Exceptions from MFP 8 Java Adapter to Client?

Question

I wanted to know, if there is a way to throw User Exceptions from MFP 8 Java Adapter to Client. I tried to throw some exceptions from the server and I get a common error. "Unexpected error... check server". Is there a way where we can throw exceptions to the client, so that it can be handled at the client in the failure blocks?

Only if there is a server crash, it is handled in the failure block of the client API methods.

Java adapters in MobileFirst Foundation 8.0 are essentially JAX-RS applications. As such you can use the " exception mapper " concept in JAX-RS to define custom responses.

You can also find various examples online.
