/soap/servlet/rpcrouter throws NullPointerException?

[Antti Salonen <as...@pp.fishpool.fi>]

Hello,

I've installed Apache SOAP 2.2 under Apache Tomcat 3.2. I followed the
installation instructions on the Apache SOAP homepage, and installed
soap.jar, mail.jar and activation.jar in the server classpath. Apache
Xerces is version 1.4.1, JDK is Sun's 1.1.8.

I briefly tried the client side API, and it seems to work OK.

After installing the Apache SOAP web archive, the admin client also seems
to work OK. However, when I point my browser to the RPC router, I get an
HTTP error 500 with the following details:

---
Location: /soap/servlet/rpcrouter

Internal Servlet Error:

According to the documentation the router servlet should handle the GET
request and return the following "Sorry, I don't speak via HTTP GET- you
have to use HTTP POST to talk to me".

Do any of you have any idea what could cause this? Currently I'm
personally all out of ideas.
