Thanks!

But I'm wondering why JDE works around OS X's Java compatibility  
mechanism; JDK directories like:


/System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Home

are set up to look to the rest of the world like an ordinary Sun JDK  
installation, and you can use:


/System/Library/Frameworks/JavaVM.framework/Home

to point to the system-set current JDK (though this would not work  
with JDE's jdk-registry mechanism).


There may have been a time when this compatibility layer was not in  
place (perhaps pre-10.2?) and the two checks in jde.el for 'system- 
type darwin' were needed, but now I think JDE should at least support  
users who have their JAVA_HOME set correctly on OS X.  Ideally the  
code would be simplified by just removing the special-casing, but in  
order to support existing installations, the following patch works  
with either setting (e.g. .../Versions/1.4.2 or .../Versions/1.4.2/ 
Home) and also attempts to support non-OS X Darwin systems.  (I did  
not test the latter.)

On the Mac jde should be looking for Classes/classes.jar in your JVM directory (see thedefinition of jde-get-tools-jar in jde.el). Check that you have this file and thatsystem-type is 'darwin.Suraj
