Paul ,

 

thank you for the clarification. That explains why I did not get the
UniformInterfaceException for NO_CONTENT (204)

but I did get it for PRECONDITION_FAILED (412).

 

I sent the first lines of code to avoid sending the whole piece. Sorry
for the confusion. Trying to make the message shorter but I see I could
not beat code behavior.

 

Maybe the javadoc documentation should mention this boundary >=300 for
UniformInterfaceException.

 

So, either I have to send an empty object instead of NO_CONTENT, or
change my service response to Response and at the client side use
ClientResponse to catch any

Response.Status.


Thanks,

 

Gisella

You should get UniformInterfaceException thrown on the client side
because the response status code is >= 300.

Could you add logging to your client so you can observer the responses
being received from the server to verify that the precondition status
code, 412, was being returned:

   res.addFilter(new LoggingFilter());

The Jersey client API is not a RPC-type system where Java classes that
are exceptions are propagated from server to client. The exception you
threw on the server side will not be reproduced on the client side.
Your RestApplicationException is defining an *HTTP response* that will
be sent to the client and not an exception that will be propagated.
