Are you sure Java is installed on your web server and that you're permitted to use it? — user142162

Do you have Java installed in your web server?
Is it added to your PATH?
Does your webserver user have execution permissions on it?
Do you have enough memory available as to start a JVM?

There are so many reasons why this could fail. Try logging into your server via ssh and execute 'java -version'.
