This is a JDBC level operation and as such is generally the client responsiblity. This might be something to consider for JBoss5.x when we move over to using interceptors and Microcontainer in the JCA implementation. Easiest thing to do at this point would be to write a ServiceLocator like thing that makes the changes prior to handing out the connection to the client.
