Question

A few days ago I published this thread, and it was solved succesfully on Unix.

Now I moved to Windows and I have the same problem.

I need to execute a command from the web application. It must execute a .jar stored in the system. I looked on Google and found some changes that I needed to do.

The function to execute the command is:

<?php
if($_POST["name"] == "")
    echo "name is empty";
else{
    $path = $_POST["name"];
    //$command = 'DISPLAY=:0 java -jar '.$path'; -> Used in Unix
    //$command = 'java -jar ../../../../simulaciones/tanqueCalentamiento.jar';
        $command = 'java -jar ..\..\..\..\simulaciones\tanqueCalentamiento.jar';
    //system($command);
    exec($command);
}
?>

The comments are different options I have tried. $path is the argument, but decided to put directly the path, to clarify my question:

Do I need a kind of “trick” as I did for Unix?

Answer 1

In windows vista, 7 (I don’t know if in others too), there is a problemm with xampp.

The apache does not stop, doesn’t matter what you do, even switch the computer off. At least for me, the solution was:

1. Uninstall xamp and reinistall it.

2. Start/stop it always as administrator:

   path\xampp\xampp_start
   path\xampp\xampp_stop

Right click: run as administrator.

In this way apache is finished properly, and I can run my command with no probleems anymore

I hope this helps
