Adam,

thanks for the adittional info. Since the request looks fine, the primary 
question is whether soapReq is constructed correctly from the request. If you 
can send me the whole example, I can try to find the problem using the eclipse 
debugger (btw: eclipse with the tomcat servlet plugin is really *great* for 
debugging servlets) as soon as I find some spare time.... (cant promise anything)

Best,
Stefan
