    How to set up OracleValidConnectionChecker

    Gunnar Bostrom Newbie


      We use JBoss 5.1.0.GA and java 1.6 and run in to trouble with org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker.

      The oracle-ds.xml contains


      <!-- sql to call when connection is created -->

                          <new-connection-sql>select 1 from dual</new-connection-sql>

                          <!-- sql to call on an existing pooled connection when it is obtained from

                                    pool - the OracleValidConnectionChecker is prefered -->

                          <check-valid-connection-sql>select 1 from dual</check-valid-connection-sql>




      If I remove the comment around OracleValidConnectionChecker I get this warning:


      08:23:24,519 WARN  [org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker] (http- Unexpected error in pingDatabase

      java.lang.IllegalArgumentException: object is not an instance of declaring class


      How can I do this correctly?


      The log says warning, but is the check done and a new connection created if the check failed?
