I installed eclipse though the ubuntu software center but I experienced some issues and I wanted to install the official eclipse version.

I downloaded eclipse classic 4.2.1 from here:

Extracted it, but if I double click "eclipse" it doesn't do anything.

Any ideas how I can fix this?

my eclipse.ini looks like this

-startup

plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar 

--launcher.library

plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120522-1813

-showsplash

-vm /usr/lib/jvm/java-7-oracle/bin/java

org.eclipse.platform

--launcher.XXMaxPermSize

256m

--launcher.defaultAction

openFile

-vm

/usr/lib/jvm/java-7-oracle/bin/java

-vmargs

-Xms40m

-Xmx512m

I also deinstalled openJDK and installed jdk7.
