You don't need to uninstall it - you can install Oragle's Java & then
set the alternatives (sudo update-alternatives --config java) to point
to the java you wish to use.

But if you still wish to uninstall jedit & openjdk, why not just purge them:

$ sudo apt-get purge jedit* openjdk-6* Java-wrappers* icedtea*
