testing http://localhost/axis/EchoHeaders.jws?method=list gives a soapenv:Server.userException (java.lang.NullPointerException)

Hi all

I'm trying to run the EchoHeaders.jws in order to validate my SOAP endpoint,
but I get the follwing xml fault in my browser:

Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/soap/server/ServiceManagerClient

I'm quite new when it comes to servlet engines but I followed
axis-1_1\docs\install.html without any problems until now. Does anyone know
why?

best regards
