Can't find struts DynaActionForm property with JSTL

[Helen Ge <hg...@mamsi.com>]

Hi,
 
I am using Struts DynaActionForm object dataForm (session scope) to hold a
form data. It is no problem to display that form bean property in the JSP
page by using the Struts bean tag <bean:write name="dataForm"
property="check_id"  />.
 
However I'd like see how the JSTL works by using JSTL without specifying
scope <c:out value="${dataForm.check_id}"  />, it gave me exception like
this:
javax.servlet.ServletException: An error occurred while evaluating custom
action attribute "value" with value "${dataForm.check_id}": Unable to find a
value for "check_id" in object of class
"org.apache.struts.action.DynaActionForm" using operator "." (null)
 
If I specify the sessionScope as <c:out
value="${sessionScope.dataForm.check_id}"  />, then there is no exception
thrown, but no value returned from check_id property.
 
I am using Tomcat 4.04, I have JSTL 1.0 installed. 
Can someone help me out ?
 
Thanks

Your syntax for <c:out> is correct using ActionForms, but for
DynaActionForms you need to do this:

<c:out value="${dataForm.map.check_id}"  />
