Hi,
So RMI is scary too. I thought that the java security model has
facilities for this. One such feature is SignedObject. We need certificates too.
Doesn't the java security model deal with code outside the sandbox? A
SignedObject is for the purpose of creating authentic run-time objects.
And people who've examined that risk may well understand the changes (and
the factors driving them) better.

You can cache the datasource which you get from JNDI and then just keep
asking for connections. Since you should be using a connection pool, the
cost to open and close the connection is very low - just getting one from
the pool or putting it back.
