I have just run the TcpTunnelGui properly and see on the receiving side the fault cod and fault string. They are: <faultcode>SOAP-ENV:Server.BadTargtObjectURI</faultcode> <faultstring>unable to resolve target object: xxx.ClientApp</faultstring>
So does this mean that its not finding the service? -----Original Message----- From: Scott Nichol [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 05, 2003 4:00 PM To: [EMAIL PROTECTED] Subject: Re: SOAP getValue() returns NULL TcpTunnelGui is a relay. You change the host:port part of the URL in your client to point to it. So, if you start it like java xxx.TcpTunnelGui 81 localhost 8080 you should change the URL in your client to point to localhost:81 instead of locahost:8080.
