Yes, I tried this, and I see that xmlblaster goes into a polling mode with the
database when it loses it network connection. After restoring xmlblaster's network
connection I see it recover based on the output:
[Jun 17, 2004 11:33:24 AM INFO
JdbcConnectionPool-jdbc:oracle:thin:@continuity:1521:alexis] Successfully reconnected
to database
But when it comes to restart a client that was logged on just before the net
connection was severed, connection fails. But if I start my client with a username
that did not log on before the database reconnection, they can log on ok. I have to
restart xmblaster for it to begin accepting connections from clients that logged on
before the db reconnection. Here's part of the server output that shows the connection
error:
