I have an intern who's bout to graduate from a state university and has taken 0 classes on the implementation of compilers or databases. Java, Java. Java.
I'd say don't worry: I almost never use anything I learned in school.
The Java was to shallow as was lots of other stuff.
School is just there to convince your first few employers so you can het a chance to see how it is actually done.
Oh, and to give you the credentials to stop annoying sales guys that are about to convince your boss that "you need Active Directory because your network is slow". (Guys company had botched a certain server install and tried to solve it by selling even mire stuff. )
