calling a java program with shell_exec()

[Martin Hampl]

Hi,

I couldn't compile php with java support on Mac OS X so I thought I'd
call my java program with shell_exec(). It does work for simple programs
("hello world") but if the program gets more complex php just gets back
an empty string (although on the command line the java program prints
out what I want).

Any ideas why this happens?

Thanks,
Martin.

Environment differences probably; CLASSPATH and PATH being two environment
variables that spring to mind.

Try running it using exec() instead and capture the return code; this might
also give a clue.

Ah. Thanks.

The return code is 1. I called java with -classpath but no success. I'll
try again tomorrow.
