[mary-users] client Java application

[Ingmar Steiner]

Dear Nikolai,

further to Marc's response, here is some general advice to solve issues 
like this.

You should set the Mary server's logging level to DEBUG and pay close 
attention to what is logged when you send your request, since that will 
allow you to understand exactly what is going wrong.

To take it a step further, I would recommend debugging it in your IDE. 
You should be able to start both your application and the Mary server 
with a debugger attached, and inspect the relevant variables at 
well-placed breakpoints in either thread (see stacktrace).

Best wishes,

-Ingmar
