Loading jdbc driver when jar is created

[Dan]

Have a very simple AWT application accessing a PointBase db. Everything works
fine when created within VisualCafe development environment. After jar is
created manually, launching app throws exception when Class.forName ("com.pointbase.jdbc.jdbcUniversalDriver");
is executed to load the driver. Tried adding several different jars(documented
by PointBase) to the creation of the final jar, etc.,but still get same exception.

Would appreciate some insight into why the driver load is different in the
jar environment.

Thanks in advance.
