It has been long period since Tomcat is upgraded to 6.0 and 7.0, but still Parallel Plesk does not support even Tomcat 6. New Java Applications does not run on Parallels Plesk Panel 10.2. By this, users can say that Parallels Plesk Panel is outdated. I am also using Plesk Panel. I feel the pain. It hardly takes sometime to make this done.
