No client transport named 'null' found

[Axel Burwitz <ax...@arcor.de>]

Hi,

sorry for that simple question, but I am a newbie to Axis/SOAP and up to 
now I am happy to have set up Tomcat and Axis, to have written and 
deployed a very simple services, can see the WSDL...

but now, when I want to call the service from my next PC in my LAN with 
a very simple client program (in fact the SimpleDVDStore example from 
the book "Java Web Services mit Apache Axis"),

it runs into "/No client transport named 'null' found"/ !

All Axis-specific .jar's are here and the CLASSPATH's are set, in 
Eclipse and outside...

Can anybody of you experienced people help and tell me what I could look 
for ??

Thanks in advance,

Axel
