Admin panel has no java

Hey guys, I’m new here, so correct me if I’m wrong, okay…

I am building a wordpress site for my college department symposium and the install goes on fine. But the admin panel doen’t have any drop-down menus and widget drag-drop won’t work! I am using wordpress.com for my blog and i have tried tried to run a version of the college’s site locally on my mac. And yes, it works perfectly on my mac. Then why not on my remote host?
Could it be a permissions problem? And btw, I used fantastico provided on cPANEL as well, but nothing seems to correct the error!

HELP ME OUT HERE!
