don't know if i got you right, but i've understood that you want to
remain the application runnding, only the db-frames should be closed,
right?

well, one possibility would be a good oo-design, for example to create a
dbConnect-object (no sir, that's *no* bean, you have to do it!) which
has a vector of frames. so if a new dbFrame is opened, each reference of
these frames is stored in the vector.

this dbConnect-class must (besides the logon-method) also provide the
logout-method (or, instead a finalizer), which then should call the
dispose()-method for each frame.

btw., you should define at least the logon - and logout-methods static,
better, make the whole class a
SINGLETON (if you don't know about a singleton, a good book to read is
"design patterns" from gamma/helm/johnson/vlissides)

hope this helps
