Java Connectivity - No classes appearing in the Java Beans Classes dropdown

Hi,

VERY NEW user to Crystal Reports. I am trying to create a report using a java class as a datasource. I have updated the setting in the CRConfig.xml file, and can get the Java Beans Connectivity screen to appear, but is shows none of my classes in the dropdown. I found a knowlege base entry that indicated this problem was caused by the JavaBeansClassPath value in the CRConfig.xml file being invalid. But I've verified the location and it is pathed directly to the classes.

Not sure what I am missing, but any help is greatly appreciated.

Thanks!
