How to work with file by absolute path in java launched via exec in php on linux?

Question

linux

I run jar through the console - everything works

java -Xms128m -Xmx512m -d64 -jar indexer.jar /var/www/html/storage/movie.mp4 1 1 i7

I run the jar script from php via exec - it does not find the file "/var/www/html/storage/movie.mp4"

$answer = exec('java  -d64 -jar indexer.jar '.$path.' '.$type.' '.$movieId.' '.Constant::INDEX, $out);

What could be the problem? Don't have file permissions? Or something with exec paths?
Works on Windows

Answer 1

Did chmod + chown and everything worked.
