Hi,
I've a question concerning JBoss and JDBC. We're generating reports using
JExcel and JDBC. After generating one report (we receive the DB-connections
using JNDI), the ConnectionManager seems to close the DB-connection. Do we have
to close the connection manually and get a "fresh" connection from the pool?
Here is our Exception:
2008-03-27 19:22:07,501 INFO
[org.jboss.resource.connectionmanager.CachedConnectionManager] Closing a
connection for you. Please close them yourself: [EMAIL PROTECTED]
