Default Installing Eclipse IDE in Fedora 3

Hi everyone,

I'm a newbie to this forum, and also to Linux, so excuse my ignorance. :)

I've recently installed Fedora 3 on a PC that was formerly Windows, and I've been reasonably happy with it so far. The installation went fine, and the only problem that I've had so far is installing the Eclipse Java IDE 3.0.1

I've downloaded the file from the www.eclipse.org site in the root account, in a .zip format. I selected the "x86 GTK2" option as that was specified for a Intel PC with Red Hat. I then unzipped the file to a folder just off the root directory, and tried clicking on the eclipse cog icon to start up the program. I also unzipped the "startup.jar" file to a subdirectory of the unzipped eclipse folder.

When I clicked on the cog icon to start Eclipse, a error dialog appeared, referring me to a log file in the configuration subdirectory. In it's entirety, this log file said:

I know that I have Java on my machine because I am able to use it fine from the command line.

Any ideas? Is this a common problem when trying to install Eclipse in Fedora? Once again, apologies for my ignorance, I am a Linux newbie. :)

Thanks
