Cannot start RTC client - Fedora 12

Hi,

I'm trying to start the RTC client on Fedora 12 x86_64. The server is working fine on the same machine..
However the client is the 32bit as it is the only one I found for Linux.
I'm going into the eclipse folder and fire eclipse executable. After some time the prompt comes back with no error.
I have tried to run the launcher but with no luck:
java -jar plugins/org.eclipse.equinox.launcher_1.0.101.R34x_v20081125.jar

I had this error first:
ZoneInfo: /usr/share/javazi/ZoneInfoMappings (Too many open files)
ZoneInfo: /usr/share/javazi/ZoneInfoMappings (Too many open files)
But after following this post "http://forums.fedoraforum.org/showthread.php?t=226971" they disappeared.

Regards,
Borra.
