Malai,
Until Wade can answer with some more assistance, I wanted to let you know
that you "should" be able to run any code developed on previous versions of
java on the newer JDK. If you look up the release information on Suns site
for 1.4 it should have notes on any issues for moving from 1.3 to 1.4.
With that said you may find that you can rewrite the code for 1.4 and it be
simpler or faster or no change depending on if there are any new features of
1.4 that you can make use of.
Sorry that I can't be of more assistance on this.
Doug
