Further along, new problem...

Hi,

I'm still struggling to get a helloworld SOAP service/client combo 
going. I've gotten a little farther than yesterday, but now when I call 
call.invoke(), the client gives me this stack trace:


java.lang.NullPointerException
        at 
org.apache.soap.transport.TransportMessage.read(TransportMessage.java:206)
        at org.apache.soap.util.net.HTTPUtils.post(HTTPUtils.java:333)

        at org.apache.soap.rpc.Call.invoke(Call.java:205)
        at hello.Client.main(Unknown Source)


Meanwhile, I get this stack trace from Tomcat:

I believe everything is in order; the service, client, and descriptor 
look fine. Any idea why I'd get this?

Thanks,
