setting basic offset (indentation)

[Chuck Irvine]

It's a simple enough question, but I've poked around now for half an
hour trying to find the answer. I give up. JDE's default indentation
offset is 4 spaces. I'd like to reduce it to 2. I tried setting, via
customeize-variable, c-basic-offset to 2, but that only works for until
I load the next java file, when the value get reset to 4. Thanks for
your help.
