Worked, but now get "The system tray is not supported"

[Robert Anderson]

I can't figure this one out.  I'm on RedHat Enterprise linux.

I used the jar successfully to use tomighty a couple of times.  I then went into the settings and changed something about being in the system tray.

Now when I try to start it, I get "Exception in thread "main" java.lang.UnsupportedOperationException: The system tray is not supported on the current platform."

the stack trace starts from:


        at org.tomighty.Tomighty.main(Tomighty.java:58)

So if I remove my settings it should work again, right?  Well, I removed .tomighty from my home dir, and restarted.  Same error!

Are there settings stored somewhere else possibly?  Otherwise I'm confused why it isn't returning the original behavior I saw the first time I started it.

Any help appreciated.

Hi Robert,

The .tomighty directory is the only place where settings are stored.  The strange thing is, since Tomighty used to work in your environment, a change in the settings should never cause that error.

Please send me the following info:

- Which desktop environment you are running (version included).

- Which version of Java is installed in your system.

Regards,

Célio

Hi Robert,

I think the problem might be that the JVM is running in server mode in your machine, which means it's running headless (I'm not 100% sure about that though).  Oracle's JVM tries to guess which type of host system it's running on and then sets the run mode accordingly.  In your case the JVM determined that your system is a server machine, which seems to be incorrect, right?

Try running some other Java desktop application, like JDownloader for example.  If my guess is right, then the same problem should happen to any other Java desktop app as well.

Thanks for the help.

My machine is not headless, that's right.

JDownloader started up ok. 

I've been able to run under a VM, so if this issue proves difficult to figure out, I guess that's a workaround for me.
