On the Advanced tab for an authentication mechanism, you can edit the following property values. If you change either value, select Apply, then select Synchronize to update the corresponding Ant configuration script:
djcClassLoader The name of the custom class loader, which reloads classes when you refresh the connector. If not specified, classes are loaded by the Java system class loader, which means you must restart the server to use new versions of the classes.
resourceAdapter The name of the connector to which this authentication mechanism applies.
