I have the same error.
I have a Datasource with a sun bridge jdbc-odbc for Access Database, and I get the same error.
I
test correctly my datasource in Bea Console, but when I try to get the connection from my Datasource in my App, I get this error.
I change this datasource to connect with a MySql Database, and my App works fine. Also, I removed the datasource from my App and I used the DriverManager, all works fine.
I don't know what's happen!!! I just think that it's imposible connect Weblogic with MS Access with JDBC-ODBC. Anybody knows if it's possible? And How?
Thanks
