PHP command shell_exec() not working for my custom Java app5

Question

I have made a custom java program to output a license and am trying to run it in php.

$deviceid=\"12345\";
$command_app = \'java -jar /home/myname/secure/myc         


        

Answer 1

My first instinct is that the command java is not in PHP's shell path. Try something like this:

$command_app = '`which java` -jar /home/myname/secure/mycommand.jar ';

The command which java will return the full path to the java executable...
