however it is better to specify source as well.
I normally specify debug as wee, otherwise all line number
infromation is stripped.
<javac source="1.4" target="1.4" debug="yes">
thanks for the pointer with using source, btw it's also mentioned
in the manual but i had never to 
the classes are getting bigger if i use debug="yes" ?

> Does it work as expected, when running those classes with jre1.4 ?
Yes, unless you use methods that only exist in java 5.

i just saw in the manual of <javac> that there's also a compiler
attribute where i can choose 1.5.
Does that mean i can stay with my workflow running on jdk 1.4 
and all i need is the javac.exe from 1.5 in sight for ant  if i need
to compile for 1.5 ?
How do i link to jdk5/bin/javac.exe, just put it on path ?
