multiversion JAR 1

[acent]

Greetings,

I'm wrote a program in version 1.5 then packaged it into a JAR. All is well. The program works great!

That is, until I tried to take the program to one of my user's computer who has JRE1.4 installed. On his computer the same program produces a "Could not find main class. Program will exit." error.

I'm assuming this is because of the difference in the java versions. If so, how do I create a backwards compatible JAR? The program is not all that complex, it simply reads a couple files, and copies a file if necessary, so I don't think I'm using anything new from 1.5.

Any help is appreciated.

It hasn't anything to do with jar - but with the compiler.

use:

javac -source 1.4 -target 1.4
