Environment variables for Java

Question

Hi,
I installed jdk1.6.0_02 from Sun, and set the following environment variables:
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/usr/games:*/home/username/jdk1.6.0_02/bin*
export LD_LIBRARY_PATH=/home/username/jdk1.6.0_02/lib
export JAVA_HOME=/home/username/jdk1.6.0_0
I issue the following commands:
which javac
*/home/username/jdk1.6.0_02/bin/javac*
which java
*/usr/bin/java*
why is it referring to */usr/bin/java* instead of */home/username/jdk1.6.0_02/bin/java*
How can I solve this problem under Ubuntu 8.04.
Thank you in advance,

Ok */ust/bin* is needed in the PATH. Why it affected java but not javac then?
Provide an instructive solution or an instructive comment if you have.I should have thought it would have been fairly obvious that it was because javac was not in /usr/bin (and that it would have been just as easy to be certain, i.e. type "ls /usr/bin/javac"), but I guess not.
I also would have thought, that it should be fairly obvious that a search path will always be read in a specific order (after all that is one of the reasons to have one, so that command searches aren't random), and, extrapolating from there, that it should be fairly obvious, considering the problem observed, that that search order was from left to right, but again, I guess not.
Use your head for something other than a paper weight, and maybe you wouldn't need to become either defensive or aggresive, but, once again, that must be something that's beyond you.
Learn how to type "How to configure path environment variable" into Google, and maybe the same would apply, but, once again, that is probably something that's beyond you.
