14.4.3. Datasource Extensions
Datasource deployments can use several extensions in the JDBC resource adapter to improve the connection validation, and check whether an exception should reestablish the connection. Those extensions are:
| Datasource Extension | Configuration Parameter | Description |
|---|---|---|
| org.jboss.jca.adapters.jdbc.spi.ExceptionSorter | <exception-sorter> | Checks whether an SQLException is fatal for the connection on which it was thrown |
| org.jboss.jca.adapters.jdbc.spi.StaleConnection | <stale-connection-checker> | Wraps stale SQLExceptions in a org.jboss.jca.adapters.jdbc.StaleConnectionException |
| org.jboss.jca.adapters.jdbc.spi.ValidConnection | <valid-connection-checker> | Checks whether a connection is valid for use by the application |
JBoss EAP 6 also features implementations of these extensions for several supported databases.
