If you use

ThreadLocal

storage then don't forget to do the cleanup.

ThreadLocal is a handy class for simplifying development of thread-safe concurrent programs by making the object stored in this class not sharable between threads. ThreadLocal class encapsulates non-thread-safe classes to be safely used in a multi-threaded environment and also allows you to create per-thread-singleton. A typical example would be:

 �
public class HibernateUtil {
 �
public static final ThreadLocal local = new ThreadLocal();
 
public static Session currentSession() throws HibernateException {
Session session = (Session) local.get();
//open a new session if this thread has no session
if(session == null) {
session = sessionFactory.openSession();
local.set(session); 
}
return session;
}
}
