copile java 1.5 code

[Tim Oliver Wagner <lists at wagner-www dot de>]

Hello,
I need to compile a java program. This one is written with java 1.5. It does 
not work to compile the program correct.

I wrote a little program to solve my compile problems, but it still doesn't 
work. I hope someone can help me. Or is it just at the moment not possible to 
compile java 1.5 code?

The little senseless program is append to this mail.
