When I run command from console, like this, it works:
java -cp /root/weka-3-6-11/weka.jar weka.filters.unsupervised.attribute.Remove {Parameters come here}
But when I run it with PHP, it gives me an error, I think it doesn't use the provided classpath:
exec('java -cp /root/weka-3-6-11/weka.jar weka.filters.unsupervised.attribute.Remove {Parameters come here}');

Somewhere I have read that PHP uses its own class path for java, but I cannot get it to work. So far I have tried to execute these lines before the exec command, but still the same exception:
echo getcwd() . "\n"; // /var/www/yugo_api/web
exec("env", $output);
print_r( $output ); // output is below
