without trying to uninstall the default Java package. For 
example, running Eclipse with Sun's (Oracle's) Java:

To run Eclipse with an alternate Java runtime environment, 
the path to the Java virtual machine's binary must be 

Once the path to the virtual machine's binary has been 
identified, try running Eclipse with the following command:

  ./eclipse -vm /path/to/jre/bin/java
