Software :: Remove Old JRE / When Log Into Other Accounts Its Points At The Old JRE?

I have JDK 1.6 update 13 installed on my machine from binaries. For my java web applets to work, I had to install JRE 1.6 update 12 from the Debian repos. I downloaded a webstart app the other day that should install a programing emulator for me, but it can't seem to find my JDK or my version of Netbeans (everything built from binaries). On another forum, someone suggested that the JRE was the problem, so we linked every referece we could find to a JRE to my JRE in the JDK folder. JAVA_HOME, my PATH and even the /usr/java directories point to my JDK. For some reason, if I log into other accounts, every variable seems correct, but the account still points at the old JRE? My solution was just to remove the old JRE so everything would be forced to look at the newer one, but I can't every time I try, I am told that Open Office and several libraries will be removed also. Is there some way to remove just the old JRE and its two basae pacakages without the rest of my programs?
