[Typo3] Problem to include java in typo3

[pol.daems at eisleck.lu]

 Hello list,

I have a problem,including JAVASCRIPT in Typo3
I know that Typo3(PHP in general) still has problems to collaborate with
java.

I tried something with an extention,which didn't work
Then,I inserted a sysfolder in my new projet, put the java class and the
java itself into this folder.I thought I could solve the problem with the
t3lib_exec.
But infact the page stays blank.
Has anybody of you tried to include javascript into his project,and found
a more or less acceptable solution?
Thanks for your help
