Thanks for hepling me. here is the code

<form-bean
       name="SetupForm"
       type="org.apache.struts.action.DynaActionForm" dynamic="true">
       <form-property name="custName" type="java.lang.String"/>
       <form-property name="typeName" type="java.lang.String"/>
       <form-property name="typeNameDesc" type="java.lang.String"/>
<form-property name="confirm" type="java.lang.boolean" initial="true"/> 
   </form-bean>

<action
       path="/PrepareSetupAction"
       type="com.actions.PrepareSetupAction"
       name="SetupForm"
       scope="session"
       validate="false"
       input="/pages/Setup.jsp">
       <forward name="success" path="/pages/Setup.jsp" redirect="false"/>
    </action>



public class PrepareSetupAction extends Action {

   /** Creates a new instance of PrepareSetupAction */
   public PrepareSetupAction() {
   }

   public ActionForward execute(ActionMapping mapping,
                              ActionForm form,
                              HttpServletRequest request,
                              HttpServletResponse response)
                      throws ServletException, IOException{
       DynaActionForm setupForm = (DynaActionForm) form;
System.out.println("In PrepareSetupAction : setupform is : " + setupForm); 

       //getSetupInfo(setupForm);
ModuleConfig moduleConfig = RequestUtils.getModuleConfig(request, getServlet().getServletContext()); FormBeanConfig formConfig = moduleConfig.findFormBeanConfig("SetupForm"); DynaActionFormClass dynaClass = DynaActionFormClass.createDynaActionFormClass(formConfig); 

       try {
           setupForm = (DynaActionForm)dynaClass.newInstance();
System.out.println("In PrepareSetupAction in try : setupform is : " + setupForm); 
       }
       catch (Exception e) {
           //logger.error(e);
       }

       //request.setAttribute("SetupForm", setupForm);

When I debug after

my setupForm is null
Is your struts config as you posted earlier? i.e., the "name" attribute refers to a Dyna form that doesn't exist in the "form-beans" section? That won't work. 


ModuleConfig moduleConfig =


RequestUtils.getModuleConfig(request,
getServlet().getServletContext());
        FormBeanConfig formConfig =
moduleConfig.findFormBeanConfig("CustForm");
        DynaActionFormClass dynaClass =
DynaActionFormClass.createDynaActionFormClass(formConfig);

        try {
            setupForm = (DynaActionForm)dynaClass.newInstance();
one of the user suggested that when I initialize a form-property in struts-config using initial="true" 
I have to use the above to prepopulate the form.

is this right?? Am I using at the right place.
If Struts is configured the form will have already been created on entry to the Action.
I think you need to back up a step and check your configuration. If you post the relevent sections again as they exist now we might be able to help you better.
Right now things are wrong, and I find it highly unlikely you would _ever_ need or want to instantiate a form inside an Action.
