The exception sorter checks SQLExceptions.
It is a jboss/vendor specific class:
It is less useful than check-valid-connection-sql,
The exception sorter only checks errors after you have run an sql statement,
meaning you have to have one failure visible to the application.
thanks fro your prompt reply.
I have got another questions about the check-valid-connection-sql, in the database-ds.xml file does this tag allow to test the connection to the database?
On the other hand if I have got a DB server and Jboss server installed on two different machine and the network goes down and resumes up,Is JBoss able to establish the connection if it breaks due to network problem, on its own?
Thanks again for helps
