Thanks for your kind help.

<%=ActivityForm.getBusinessCollection().size() %>
gives JSP processing error.  Somehow, ActivityForm
cannot be recognized. 

The struts tag for retrieving the size does not give
runtime error, the web page is displayed.  However,

<bean:size id="size" name="ActivityForm" 
property="businessCollection"/>

does not display anything (it looks like the
<bean:size ...> does not exist.)  I know that the
'businessCollection' is not empty because I have used
<logic:notEmpty ...> tag to test it before I try to
write out the counts in that collection.
