I'm having a rather annoying problem, to do with database access.

        Basically, I have a bean that opens a connection to a database, does
an SQL query, then returns some data. The bean works fine and accessing the
jsp page I made displays all of the results ok. However, a short while after
accessing the data, the JVM crashes totally. It throws up an illegal
operation in windows and shuts down.

        My best guess is that this is happenning on garbage collection, so I
tried cleaning up the database connections. At the end of the access my bean
now calls the close() methods of the ResultSet, Statement and Connection in
that order. This seems to cure the problem.

        Does anyone know why the garbage collection was crashing the JVM and
why it does not seem to happen in applications, just when used in a servlet?
