Subject RE: java.lang.InstantiationException: Unknown JDBC driver: com.my sql. jdb
Date Fri, 19 Dec 2003 23:32:51 GMT
i am using the mysql jdbc driver that came with Torque
C:\torque-gen-3.1\lib\mysql-connector-java-3.0.9-stable-bin.jar. Are you
saying I should use an older driver, from where? can you explain in more
detail?

Try using the older mysql jdbc driver located in the
same jar and see if that works. There was a post in
the list several days ago with similar issue and it
was resolved by using the latest versions of the
dependency jars.
