If you don't need ORACLE Java, you can switch to Icedtea Open JDK. But to your problem: To completely uninstall a package just type into an terminal

sudo apt-get purge PACKAGENAME

in fact of Oracle java it's

sudo apt-get purge oracle-java7-installer

and then install jre6 again

sudo apt-get install openjdk-6-jdk

Are you sure, you have Oracle Java installed? Because from Ubuntu 10.10 the Oracle Java isn't a part of the package-sources anymore... Did you install it manually?
