ClassCastException when accessing WS

Question

I developed a small sample webservice using the JWSDP. It works fine when I invoke it's methods locally and deployment to Tomcat seems to work as well, at least the .war file is unpacked and I get the "A Web Service is installed at this URL......" page when I point my browser to the according URL.
Now I wrote the simplest possible client to test the service's accessibility. It's supposed just to invoke a SOAP call to one of the methods and display the result, everything hard wired. First weird thing is, when I just use the service's URL, I get a SOAP Fault stating: "Missing port information". I can get past that if I add the port's name. But that doesn't do the job as I now get another SOAP Fault: "Internal server error". In the Tomcat logs, I found out a ClassCastException occurs somewhere in my service class. This is quite strange, because neither the service class nor the client contains any class cast.
I read that duplicate jar files in the classpath are a common cause for ClassCastException, but not in this case, I made sure I do not have double jars included.
Any suggestions where I could search for the error?
Many thanks in advance!

Hello..
I am also getting the same ClassCastException , while accesing the deployed webservice from my client program.
I have deployed a simple webservice which is developed accroding the the article from sun, and deployed it succesfully on Tomcat, (Tomcat has come with JWSDP1.1 installation).
I can see the following message from the browser after deloying the webservice,
A Web Service is installed at this URL.
It supports the following ports: "SunRegPort" (http://localhost:8080/SunReg/jaxrpc/SunRegPort)
I tested with Tomcat Admin manager (http://localhost:8080/manager )and observed that my service is running on tomcat server,
BUT....
while trying to access the webservice from the standalone java client program, I got the "java.rmi.ServerException: Internal Server Error (java.lang.ClassCastException: com.sun.xml.rpc.server.http.ServletEndpointContextImpl) "
The server logfile is also populated with the same error mesg.
I made sure that the proper classpath is setup, but stil.... :-(
Here is my client code snippet:-----------------
SunRegService_Impl s= new SunRegService_Impl();
          System.out.println("SunRegService_Impl :--> "+s);
          SunRegPort_Stub stub = (SunRegPort_Stub)(s.getSunRegPortPort());
System.out.println("SunRegPort_Stub :--> "+stub);
stub._setProperty(Stub.ENDPOINT_ADDRESS_PROPERTY,"http://localhost:8080/SunReg/jaxrpc/SunRegPort");
System.out.println("Property set :Done ");
          Course course = (Course)stub.getCourseInfo();
System.out.println("Course :--> "+course);
          cid= course.getCourseID();
          cinfo = course.getCourseDesc();
Is there anything wrong with my code ? anybody has some idea how to get rid of this problem ?? Thanks in advance
