^^^^^^^
I am not sure what you mean at this ^^^ point.
Unless "default" is a symbolic link that points at "jre1.6.0_03".
The "ls -l /usr/java/" command will show this.

As mentioned, you want to update your $PATH and $MANPATH.
Looking at your output above I would suggest running these shell
commands:
PATH=/usr/java/jre1.6.0_03/bin:$PATH
MANPATH=/usr/java/jre1.6.0_03/man:$MANPATH
export PATH MANPATH
The other thing that java tends to like is the $JAVA_HOME variable.
You might usefull do this instead:
JAVA_HOME=/usr/java/jre1.6.0_03
PATH=$JAVA_HOME/bin:$PATH
MANPATH=$JAVA_HOME/man:$MANPATH
export JAVA_HOME PATH MANPATH
The see if "man java" produces a manual page. (Be warning, it's a very
long manual page!) Also see if "java -jar filename.jar" now behaves
better.
