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?
Regards
Gunnar
