Better still, lets go back to basics and trace what exactly is getting
run/sourced and where. The reason I say this is that *most* GNU Linux systems
(and many Unix varieties) actually use /bin/sh to run the X session login/setup
scripts. This is why the values Matt has in his ~/.bashrc are not being
executed. 

The simplest solution I've found is to change the Xsession script that sets up
your session to be a bash login shell - then ~/.bash_profiel (or ~/.profile)
will get sourced prior to the window manager being started and everything that
is then spawned by the window manager (using menus, 'run' boxes or start icons)
will inherit the users login env. 

The point Pete mentioned about JAVA_HOME being a site wide variable is quite
valid. It would be reasonable to stick the JAVA_HOME environment in
/etc/profile as long as all the paths are also site wide/readable (i.e. java
classpath does not have user directories in it.)
