It really depends on what you mean by joining back in with the old one. It
is common practice for a server to have a thread pool. When a client
connects, a thread is selected from the pool to service that client. When
the client disconnects, the thread is returned to the pool. Once the thread
is returned to the pool it is back in its idle state and it's not really
doing anything aside from waiting for the next request. In this way you
can pre-populate the pool with some threads and there is likely to be one
ready when a client connects; there are other benefits.

Is there a reason you need a continuous connection and that a request-based
connection (HTTP) using existing J2EE server technology would not be
appropriate? These tools tend to already have such facilities built in.
