Frequently Asked Questions for NetBeans Project Opener

Q: Application doesn't start, what's wrong?

A: The problem might be incorrectly detected proxy settings by Web Start client. Proxy settings are supposed to be detected from browser settings by default, but there might be some situations where the detection fails. Start Java Control Panel either from Windows Control Panel or from command line. On windows execute command:

(jre install dir)\bin\javacpl.exe

on linux execute command:

(jdk install dir)/jre/bin/jcontrol

and verify that Network Proxy Settings are set correctly. If there is 'Use Browser settings' you might want to provide explicit proxy server.
