My expectation was that Resteasy would catch this exc= eption and return an appropriate response, but not log the exception. This = creates a lot of output in the server logs. * What is the most appropriate way to specify a response status? I could re= turn Response but it seems cleaner to return a specific type and throw WebA= pplicationException for errors. I created the following test case: | @GET | @Path("/status/{code}") | public String getStatus(@PathParam("code") int statusCode) { | throw new WebApplicationException(statusCode); | } | = No matter what code I specify, the exception stack trace is logged to STDER= R and I get the JBossWeb default error page back (even if I modify the code= to specify no content). * This behavior caused me to question my understanding. Should I not specif= y a response status by throwing a WebApplicationException? Should I instead= return Response or use a custom exception with an exception mapper? In a p= roduction environment I do not need to log a stack trace for 401, 404, etc. * Is it possible to disable the default error page and return an empty resp= onse? I tried changing the test case to throw new WebApplicationException(R= esponse.noContent().status(statusCode).build()); but I still get default er= ror page. * I was also surprised to see the exception logged to STDERR. The documenta= tion says that Resteasy uses slf4j configured or log4j. Perhaps I have some= thing configured incorrectly? I have tested this behavior with Resteasy 1.0.2GA and 1.1RC2. I am running = on JBoss 4.2.3.GA. = When I request this resource with /status/401, I get the following response= (output is from curl). = | < HTTP/1.1 401 Unauthorized | < Date: Thu, 28 May 2009 16:36:38 GMT | < Server: Apache | < Content-Length: 948 | < Content-Type: text/html;charset=3Dutf-8 | * Connection #0 to host localhost left intact | * Closing connection #0 | JBossWeb/2.0.1.GA - Error report
