I have Eclipse 3.5.1 and Java Portable (from Portableapps.com) installed on a portable hard drive and would like to point my Eclipse to use the portable apps Java version. This will allow me to use Eclipse on a computer even if Java isn't installed. How do I accomplish this?
Perhaps take a look at the Eclipse Portable project on SourceForge
EDIT: Alternatively, edit the eclipse.ini file and add:
-vm
..\path-to-jre\bin\javaw.exe
[The new line after -vm matters]
