run SOAP sample

I am playing with SOAP samples (Apache SOAP 2.0, Tomcat 3.1).
Unfortunately, I received exception for all the three samples (see below).
Could someone tell me what's wrong?  Thanks in advance.

Best,
Jenny

Why not IIOP??

Posted by Ramakrishna Srinivasa <ra...@wipro.com>.
I read this line in one of the SOAP articles..

Existing RPC-style Protocols such as DCOM and IIOP have not proven to be adaptable to
the Internet.They require a non-trivial amount of dedicated  runtime support.

Can anyone explain me why??

What is the sort of RunTime support and how is it not required for SOAP??

As far as I know for RMI..It doesnt even require a WebServer whereas SOAP over HTTP
requires a WebServer.

Have I gone wrong somewhere??with the basic understanding???

Thanks
Ramki.

That was your client being unable to parse the response from the service

That was the problem - QName calls a parser method that does NOT
exist in the parser that your server is finding first.

Even if Xerces.jar is first on your classpath, Java will find
an earlier generation parser if it is in the 
 JDK/jre/lib/ext  directory.
