Configuration : Jboss-4.0.5, with EJB-2.1 and jdk1.5

I have the above configuration and now would like to implement the web-services. I downloaded JWSDK-1.5 and use JAXRPC style. After starting the server the jboss/server/default/data folder doesnot contains the WSDD file and it doesnot display the message saying WSDD is published. Let me know what could be the problem....

Thanks in advance...
