If you're using JNDI to get a DataSource and calling getConnection(...) 
on it to obtain a JDBC connection, then there's no connection pooling 
going on. You close your connectoins when you're done with them. So 
there's no need to tell the DataSource the connection is broken; you 
just close it and request a new one from the DataSource.

I don't currently use JNDI in my own app (though it looks like I 
should), but I'm pretty sure that's how to handle it.
