If xmlblaster should lose its connection to the persistent database store (like oracle), can it automatically reconnect when the connection is restored, or does xmlblaster need to be restarted?

Yes it automatically restores, just try it,



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: at 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: 

Ok, this is a bug, we'll fix it to the next release.
