"How to set up OracleValidConnectionChecker" To view the discussion, visit: http://community.jboss.org/message/605809#605809 -------------------------------------------------------------- Hi, 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> <!--valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker </valid-connection-checker-class-name--> If I remove the comment around OracleValidConnectionChecker I get this warning: 08:23:24,519 WARN [org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker] (http-0.0.0.0-8080-1) 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?
