Answer 1

You can add a map of your form to the request area as follows:

        Map m = dynaform.getMap();
    request.setAttribute("mapForm", m);

And then go into the jsp properties with:

${mapForm['nameOfYourFormProperty'] }

It uses JSTL. Otherwise, you can use this:

<%= ((Map)request.getAttribute("mapForm")).get("nameOfYourFormProperty") %>

, DynaActionForm Struts View (jsp)?

DynaActionForm Action Struts:

DynaActionForm myForm = (DynaActionForm) form;
request.setAttribute("myForm", myForm);

JSP DynaActionForm - :

DynaActionForm myForm = (DynaActionForm) request.getAttribute("myForm");
String age = (String) myForm.get("var");

Struts .
