Subject Re: Java task in Linux

The "*.jsp" is your problem. On Win* systems, every command deals with
wildcard expansion itself, which is why this works for you on your Win2K.
On Unix, wildcard expansion is done by the shell before the command is
run. Ant doesn't go through the shell, so on your Linux system your 'java'
command is being handed a literal "*.jsp" instead of all the .jsp
filenames. I think you'll probably want to look at the <apply> task, which
uses a <fileset>, and also has the added advantage of only handing off
source-files that are newer than their targets.
