Hi, I'm tryng to do a web service client with a Eclipse. In particular I hav

Ensure you are using the correct URL for the WSDL. As per the docs, this should be

http://... /suite/webservice/processmodel/<SERVICE_NAME>?WSDL

more info here: forum.appian.com/.../Publishing_Process_Models_as_Web_Services.html

If you already have this url, can you attach screenshots of the configuration of the client? Additionally, make sure that the web service is available by ensuring you can access the wsdl from your browser.

I can access to the url of the process model. The strange thing is that if I use a Process model published as web service in the Development Envirorment I can make the client using Eclipse instead using the test Envirorment I can't do the client with Eclipse (I have 3 different envirorment on my project so 3 diffent Appian web site etc.....). Why I could have this problem?

I am also attaching the screenshot of the configuration in Eclipse

The screenshot doesn't show the complete connection string, so I can't say if it is correct. Assuming this is the same string as used with the other environments, if this is working differently in different environments, are there different security configurations between them? If it is working correctly in the browser, it may be that you already have a session, which is allowing you to connect correctly.
