I have a Java Web Start application I launch with a JNLP file successfully without the corporate firewall, but I can't get around this problem:
com.sun.deploy.net.FailedDownloadException: Unable to load resource: url://file.jnlp
When I use my Mac OS X Terminal to launch it, I see:
PROMPT$ javaws -Xnosplash file.jnlp java.lang.IllegalArgumentException: port out of range:-1 ... rest of stacktrace ...
I am aware that Java Web Start tries to open a server listening on a random port for the splash screen, which is why I try adding -Xnosplash to the command.
I know that the app only uses port 80 other than the splash screen.
How can I get the app running by myself or what do I ask my IT dept. to open up so I can do so?
