As with any other class: by passing it as an argument of a constructor or method:

MyJavaClass c1 = new MyJavaClass(session.getAttribute("foo"));
MyOtherJavaClass c2 = new MyOtherJavaClass();
c2.doSomethingWithSession(session);

Generally I would make information flow from the servlet to the class: the servlet initiates the actions it requires, passing along any information that's needed to perform those actions.

I would try to isolate the other classes from any knowledge of servlets and sessions as far as possible - the servlet should know about its collaborators, rather than the other way round.

(If this doesn't help for your specific situation, please tell us more about what you're trying to do.)
