[Resteasy-developers] LoggableFailure: Failed processing arguments of public AsynchronousDispatcher

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Greetings,

I'm interested in using RESTEasy, but having runtime problems.  I 
downloaded the beta and installed a deep copy of directory 
"resteasy-jaxrs.war" to /server/default/deploy.  I've tried to test the 
installation via existing RESTEasy components and from what I could 
glean from the source distribution (in resteasy/test/smoke), it seems 
the URL "http://localhost:8080/resteasy-jaxrs/basic" should return some 
text, like "basic".  It seems the war deploys cleanly but when I 
exercise the server with the above URL I get the following exception:

I was using my browser to issue the request.  Thinking Mozilla might be 
introducing something unwanted in the HTTP header, I also tried telnet 
to port 8080 and issuing a plain-vanilla GET on /resteasy-jaxrs/basic 
but I arrived at the same exception server side.

Looking at this in the debugger, it seems that the root cause is 
org.jboss.resteasy.core.MessageBodyParameter line 38:

MediaType mediaType = request.getHttpHeaders().getMediaType();

mediaType is coming back "null".  However, if I use the debugger to 
assign a new MediaType() with "text/plain" the immediate lines pass but 
then I get other exceptions later.

I've had this same experience on RESTEasy Beta's 5 and 7, using JBoss 
4.2.1, 4.2.2, and 4.2.3, with either JDK 1.5 or 1.6.

I'm open to suggestions and helping further the effort:  If I'm 
performing an operation incorrectly please advise.  If I can be of 
further assistance, please let me know.

Best,
Eric Kahler
