We have the environmental variable set as well.

Edit
it was working before he installed the black berry plug in.

The variable
JAVA_HOMEis not required by Eclipse. If your Java installation does not put the Java executables in thePATH, you should add those manually.A faster way to have your Eclipse up and running consists in modifying the
eclipse.iniand using the-vmoption.http://wiki.eclipse.org/Eclipse.ini#-vm_value:_Windows_Example
