Hi,
Just prepending a JAX-RS: prefix in the subject line.

You can throw a JAX-RS WebApplicationException or use JAX-RS ExceptionMappers and throw any exception you like (including the
RuntimeException), have a look at [1] please for more info :

Hi
There's an "Exception Handling" section there, and some basic examples are provided, but I'll add few more advanced
examples. If
new WebApplicationException(statusCode)
is not good enough then you can use ResponseBuilder :
new WebApplicationException(Response.status(status).entity(someDescription).build());
Cheers, Sergey

Thanks, I've been using that page quite a lot lately.
Would it be possible to edit the page and add an example of using
WebApplicationException in the text - mainly to make it a bit more
obvious how to use it. I skimmed across the paragraph refering to the
exception a few times before I connected the dots. I tried to edit the
page myself to add this.
Kind regards,
Tarjei
