Hi Marty, Has the new Servlet specification provided some better way to handle memory resources. At time we do see some DB connection remaining open or session is not invalidated. How better has it been described in you book, to handle this resources carefully. Hope I am clear. MB
Regarding session invalidation server have thier own default timeout period(in case you dont set it) after which the session will cease to exist. There was a proposal to add a logout method in servlet 2.4 but had been defered for future version. Some servers like weblogic 8.1 can detect database connection leaks. Alternatively, you can write you thread which will reclaim leaked connections.
