Hi folks, I've been having some issues anyway with Oracle in my Java app the last week or so.
Originally, I thought it was due to some references where I was using the old sun.jdbc.odbc.JdbcOdbcDriver rather than the thin Oracle driver.

So in any reference I had this, I've switched it to the Oracle thin like so:

Class.forName("oracle.jdbc.driver.OracleDriver");
 String dbURL = "jdbc:oracle:thin:@(protected)";

My error is listed below. I guess my question is, do any of you think this is mainly with Oracle, or perhaps the driver in the Tomcat lib directory got corrupt? Or is this a Tomcat issue at all even? I'm inclined to think the driver (jar file) might have gotten corrupt possibly, but that would be unlikely and that it's more of an issue with Oracle.

I welcome any feedback.

Thanks,

Barry
