Publishing failed in WebSphere Integration Developer

When publishing my Module to a brand new created ESB profile in WebSphere Integration Developer (WID), everything runs fine. But hitting the publish button after a change to republish the project was less fun.

"The publish encountered some problems and the application may not have been installed or it may have been successfully installed but was unable to start."
The reason being "Failure uploading archive to server"

I found 2 articles giving a different solution:
This technote 1414552 explains that the hostname verification service should be disabled to make sure the publishing does not mind any unresolved hostnames.


This blogpost on www.soa.si tells you that you can change to hostname in the server configuration, to make the publishing work.

None of the 2 methods worked for me. But thinking about why the hostname could not be resolved, I sudddenly saw the light: I configured a proxy in WID to access the online help system. Adding the hostname of the local machine to the "No Proxy For" list made the publishing successful.
You can find these settings in the preferences screen (window > preferences) in the general section, Network connections.
