Accessing the ActionForm object from within JSP

["Larson, Kirk" <Ki...@pearson.com>]

I want to access a form within my JSP page using JSTL.  I have it working by
simply specifying the name of the form (cycleDateForm) in the JSTL EL.
However, this does not seem like the correct method of solving this problem.
The form name is derived from the Struts configuration file using the
appropriate action mapping.  Since the JSP page only specifies the action
name and does not directly specify the form name, it does not seem that it
should reference the form directly. However, I am not sure how to determine
the name of the form object?  Any suggestions?

Sample JSP page :
==============
<html:form action="/cycledates/edit" >
	<c:forEach items="${cycleDateForm.cycleDates}" var="cycleDate">
		<c:out value="${cycleDate.key}"/><br>
	</c:forEach>
</html:form>

Relevant portion of struts-config.xml :
==========================
<form-beans>
	<form-bean name="cycleDateForm"
type="com.pearson.tools.setup.CycleDatesForm" />
</form-beans>
<action-mappings>
	<action 
		path="/cycledates/edit" 
		parameter="" 
		type="com.pearson.tools.setup.CycleDatesDispatchAction" 
		name="cycleDateForm" 
		scope="request">
			<forward name="success" path="cycledates.edit.frame"
redirect="false" />
	</action>
</action-mappings>

                      ^^^^^^^^^^^^^
The name does not correspond to the ActionForm-<class>name, that's why it
doesn't work.

It should work using <c:forEach items="${CycleDatesForm.cycleDate}"
var="cycleDate">

An alternative is to use the <bean:struts>-tag to expose config-data, see
http://jakarta.apache.org/struts/userGuide/struts-bean.html#struts
