A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run Eclipse. No Java virtual machine
was found after searching the following locations:
/usr/lib/eclipse/jre/bin/java
java in your current PATH


can anyone help me?
I already tried to uninstall eclipse and java 1.6 but that didn't work.
(Eclipse has worked before)
