[<php...@li...>]

hello,
I'd need some help in understanding why my simple code is not working.
I have a java class that computes "ls -l -a > /home/ale/output" and I want to used it from PHP.

This is it:

<?php
...
$java = new java_class('com.myProject.HelloWorld');
$inputParametersForJava=array("-l", "-a");
$java->run("ls",$inputParametersForJava,"/home/ale/output");
...
?>

The signature of the java method I'm calling is:
public static String run(String jobCommand, String[] inputParameters, String outputFile) {...}

If I add a "main" method in the class and call "run" from there (with the same parameters as above), everything works (i.e. I get the output of "ls -l -a" in the file "/home/ale/output").
But when I use php/java bridge, I get no error in PHP and no output file is created.

I know that:
- $java = new java_class('com.myProject.HelloWorld');
works because I do not have an "error 500".
- $inputParametersForJava=array("-l", "-a");
works because it's a simple arry declaration.
- The problem is in the calling of "run", but where? and why?

Thanks all for your help
