hey there...
i'm having tons of problems when trying to make the emf gmf plugins in eclipse under my ubuntu version, it's x86_64 version.

I've tried many different ways, with different eclipse versions and different plugin versions, but it always crashes anyway.

for instance, i'm getting this when trying to create models : ecore, genmodel, gmfgen, gmfmap....

i'm getting this exception:

the library exists and it's included in the plug-in dependencies.
I've tried to install the plugins both manually and through the eclipse update manager and either way gettint the same errors.

does anybody know about any known errors with EMF and Ubuntu 64?

i'm going crazy, no way I can make it work.

heeeeeeelp!

thanks!
