Problems with Hessian and Resin 3.0.21

Hello,
I try to write a webservice with hessian... and discovered a strange 
behaviour.

If I normally start Resin and want to to access the webservice, I get 
the error

[com.caucho.hessian.io.HessianProtocolException: 405: 
java.io.IOException: Server returned HTTP response code: 405 for URL: 
http://localhost:8080/test]

If I start RESIN in debug mode (with conf/development.conf), it works 
(but hot deployment seems to be disabled), but Resin is then only 
accepting POST.

How can I fix it that Resin is normally started and be able to use 
normal Servlets and Hessian?

Thanks,
Armin
