If a tool like ij is started in a new JVM, then it will not be able to connect to an embedded database which has been started by a different JVM.

Hi Kristian

Thanks for the answer.

So this means that if I open the database using the EmbeddedDriver driver no
one can access the database from an outside connection?. Includiing tools
like ij?

Unless I have misunderstood, sounds like you simply want to use Derby
embedded. This is done by using org.apache.derby.jdbc.EmbeddedDriver and
specifying the connection URL as 'jdbc:derby:myDatabase[;create=true;...]'.
By default, no network server will be started and only the JVM is able to
access the database.

Note that 'myDatabase' can point to a database by using either a relative
path (relative to derby.system.home , or current working directory if it is
unset) or an absolute path.

Did that answer you question, or do you have any further requirements?
