Hi all, i am using fedora 11.i have eclipse in programming menu of application.but, it is not opening it's console.by clicking eclipse in menu it is displaying an unreadable message alert.plz help me in this regards.

A screenshot of the error would be useful.

Alternatively, please try to launch eclipse from command line and post the output. If you don't know the command, probably you can right lick on the Eclipse icon and check the properties to find the exact command to run.

I see lots of "Too many open files" errors. Also you are using OpenJDK - I'm not sure if Sun Java is needed. Have you tried rebooting and retrying (from "Too many open files" perspective)? Also, maybe you can try with Sun Java. Sorry, I don't have any further clues on this.

openjdk shouldn't be a problem. I've been using the two together since Fedora 10.

1. Has you ever been able to run eclipse on this machine? If so, what do you think might have changed?
2. Did you install eclipse using yum?
3. Try moving ".eclipse" and workspace (default "~/workspace") directories. This will remove any eclipse plugins you've installed as well, so make notes on what plugins you want to reinstall. This will force eclipse to recreate these directories and maybe resolve your problem.
