Is the remote server running?
Do they use a different port, not both 8080?
Are there any more extensive logmessage available in the console?
Can you put your service on a sandbox and make the WSDL available so we can give it a go?
When running/testing locally you need to have both app deployed locally. If you get errors starting the second app, check that the port numbers (in your project settings) are set to different values for each app, for instance 8080 and 8081.
You can also save the wsdl as a local file and use that file instead of the url
