Can't run commands from exec()

[Ganael LAPLANCHE <ma...@martymac.com>]

Hi !

I would like to execute some commands with exec().
But some work, some won't.
Commands like mv, touch, unzip, zip, rm are OK and work perfectly well.
But I'd like to call a java application (Saxon), and it doesn't work
(java -jar /usr/local/saxon/saxon.jar ...). I've tried exactly the same command under the shell,
it worked...

Any idea ?

Thanx,
Gan.
