Question

I try to run an jar from an php file like this:

exec("java -jar /home/florinbuda/NetBeansProjects/monkey1/dist/monkey1.jar", $result);          
print_r($result);

and IT WORKS if I run it from command line like:

$ php runner.php

but it doesn’t work if I try to load it via http-localhost-server/runner.php the page just keeps loading forever without giving any error..

In the .jar file I added a simple test to now if the jar is even started to work

public static void main(String[] args) {
    new File("/home/florinbuda/Desktop/xxx").mkdir();

and as you can guess – when I call http-localhost-server/runner.php the jar is not even started to be executed…

It’s a problem of rights? What suggestions do you have?

Answer 1

Yes, it’s the problem of permission.

You should chmod the parent folder of .jar file.

chmod 755 -R /home/florinbuda/NetBeansProjects/monkey1/dist/

EDIT: And then your script should look like this:

exec("PATH_TO/java -jar /home/florinbuda/NetBeansProjects/monkey1/dist/monkey1.jar");
