Thank you Jaikiran for the your assistance. I am using Eclipse, I have added jboss-common-jdbc-wrapper.jar file which contains the org.jboss.resource.adapter.jdbc.WrappedCallableStatement; but when I try to import as follow: import org.jboss.resource.adapter.jdbc.WrappedCallableStatement; I get the following error: The import org.jboss.resource.adapter.jdbc.WrappedCallableStatement cannot be resolved. There are so many other classes in org.jboss.resource.adapter.jdbc and I have tried importing a few and they are imported successfully. I don't understand what's the problem with the one I need to import. If you (or any body) has any suggestion, please reply.
