How to use Two Action forms into one ActionClass?

[Pras Tiwari]

Hi,

Currently I am using it but it is giving me error like :-
===========================================
11:15:10,984 ERROR [[action]] Servlet.service() for servlet action threw exception
java.lang.ClassCastException: com.econify.struts.form.ViewcartForm

What should I do if I want to use two forms inside same action class?
Please help me.

I think you should wrap the 2 forms you want into one form and use that form. I don't think you can define more than one form for one action.

You can only define one ActionForm per action mapping, but more than one action mapping can point to the same Action class.

The answer to your question is yes, it is possible to have the same Action class use more than one ActionForm. Here's an example:

<action name="form1" path="/action1" type="com.mycompany.MyAction" />
<action name="form2" path="/action2" type="com.mycompany.MyAction" />


The execute() method of an Action class receives an object of type ActionForm as a parameter. It is up to you to cast this object to the correct subclass of ActionForm. The execute() method also receives an object of type ActionMapping as a parameter. You could therefore do something like this:

public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
    if (mapping.getPath().equals("/action1")) {
        Form1 form1 = (Form1) form;
        // do something with form1
    } else {
        Form2 form2 = (Form2) form;
        // do something with form2
    }
}
