syntax highlighting isn't working

Hi All,

I have spent several hours trying to get sytax highlighting to work, and I
am completly stuck.

First the good news, if I use the package/instructions at
http://www.skybert.nu/cgi-bin/viewpage.py.cgi?computers+emacs+java_configuration
then syntax highlighting works.  However, these packages are old and I
would prefer to be up-to-date.

The second bit of odd news is that syntax highlight does work for non-java
files like my .emacs file, it seems to just be in JDE that I am having
problems.

If I open a *.java file the sytax is not hightlighted, but if I do M-x
font-lock-mode the syntax is suddenly highlighted.  I don't have to do
this for my .emacs or html files though.  My .emacs file is available for
inspection at http://adhamh.com/emacs.jdee.

Here is the *Messages* buffer from emacs starting and not coloring java
files:

And here is some more information about emacs and my setup:

drwxrwxr-x 6 adhamh 4096 2007-03-07 11:55 jde-2.3.5.1/

Does anyone have any trouble shooting tips?  This seems like a pretty
straight forward issue.  I have gotten this to work on OS X, but not on
Linxu...

Thanks,

Adhamh
