PHP Shell Command

[anon538]

I am attempting to compile and run a simple java file on my server, but I'm not getting any results. Here is what I'm trying to do:

<?php
echo shell_exec("java/bin/javac Anon.java");
?>

Java is installed in a folder named java.
Anon.java is in the root directory along with this php file.
When I run the code, nothing happens. No error messages, no compiled files, nothing.
I am using Linux (GNU bash, version 2.05b.0(1)-release (i386-redhat-linux-gnu)) on the server.
Can anyone shed light on how to make this work?

Not to answer your question with another question, but have you run the command on the command line and ensured that it actually does output something?

If it does, then I would suggest a change in your code to store the value in a variable first, as such:

<?php
$return_value = shell_exec("java/bin/javac Anon.java");

echo "$return_value";
?>

Unfortunately.. .

I can't access the command line directly. I am using a shared server, and that is one of the restrictions that my host puts on me. I was just hoping that someone would see something syntactically wrong about my code before I have to go through tech support.

Have you tried it on a local development server?

Fixed

I appreciate the help, but I figured out the problem after playing around with it for a while. I was using the wrong command.
Thanks anyway,
