This issue could be related to issue <a
href="http://www.netbeans.org/issues/show_bug.cgi?id=64835">64835</a>, however
the errors I get are different.

This happens with NetBeans 5.0 beta 2, on JDK 1.5.0_05 and JBoss 4.0.3SP1

I was following the <a
href="file:///C:/Program%20Files/netbeans-5.0beta2/nb5.0/docs/quickstart-webservice.html">NetBeans
IDE 5.0 Quick Start Guide for Web Services</a> when this issue became apparent.

I was able to create the service, deploy it, register it and run the test from
the "Run" tab when my server target was SJS 8.1 2005Q2 UR2.

I then stopped SJS, set the target server to JBoss and followed the steps in the
guide to configure my build.xml for JBoss and copy the necessary JARs. I
de-registered the old service, then I deployed on JBoss, re-registered the
service with the JBoss specific URL and when I tried to run the test from the
"Run" tab I got the following SAX Exception:

org.xml.sax.SAXException: Deserializing parameter 'sayHi':  could not find
deserializer for type {urn:HiWS/types}sayHi

I am attaching the logs for JBoss from the IDE, the error window stack trace
that comes up when trying to test the Web Service, and also the jar file for
this simple service in case anyone wants to deploy it and give it a go to try
and reproduce the issue.
