Setting environmental variable for Netbeans

[Peter Ryan]

I am treading more unknown ground trying
to get NetBeans to run on 4.10.

I installed jdk 1.4.2 (thanks to help from 
here), and have installed this Netbeans 
via the ports collection.

Now when i try to run it, it wants an
environmental variable called JDK_HOME to
be set.

Using tips from searching the net, I am
under the impression I have to change a 
a file called csh.cshrc or maybe .cshrc
Then I did a find files on .cshrc, and 
found 2 copies - one under
root/ and the other under usr/home/peter.

I am logged in under root, so I am not sure
which file I should change, or even if this
is the correct file.

Could someone point me in the right
direction before I fiddle enough to have
to resinstall again :)

Thanks,
Peter
