Subject Re: ClassCastException building SqlMap instance
Date Fri, 01 Apr 2005 01:16:50 GMT
Excerpt from sql-map-config.xml:

    <dataSource type="DBCP">
        <property name="JDBC.Driver"

The error persists whether or not I place the commons-dbcp, commons-pool,
commons-collections, and the jdbc driver jars in server/lib.
Thanks for looking at this.
