RE: accessing user-defined classes from html:select and html:opti ons tags

[Philip Tucker <ph...@valtech.com>]

I added the import statement, but still get the same error.  It's in a
Struts method called "BeanUtils.populate".  I have the imported class in my
.WAR file, and I even tried placing it directly in the server class path,
but still the same error.  Any ideas?

Below is the full error text.

Thanks for the help,
Philip
