the "Password" attribute can be Called in Action as

"String password = form.getPassword(); "  as per the FormClass..

If you are Used as an dynaActionForm For Hidden purpose

the syntax Will be <formName.set("Password",<value>)>

the Passowrd Parmeter should be mention in the strutsConfig.Xml

if you set the passord value in Formbean Already Then we can Directly call that value by using " String password = form.getPassword(); "

if u Wann use that by in Action only Means just Set the Value in action as <formName.set("Password",value)> in the Form of dynaactionform, after setting the value u hav to declare that in strutsconfig.xml..

if this is not Clear Just let me know i Will Send u one Example..

Choice 1 and Choice 4 both are correct. But idealy one should go for Choice 4 only adhering to struts framework. We need to type cast form object reference got in exectue method to particular required Action Form

If the values are set from a JSP, then we need to follow the request.getAttribute() method and while revalidating the fileds, the request.getParameter() method?will be fired.

The reason for the above two is as follows,
1. While setting the values in?a JSP, it is set as an argument and the same is sent to the formbean in the form of attribute. It is an attribute because we are setting the value to that particular?validation?method.

2. At the time of revalidation in the formbean,the same value is set as a parameter.? Now since we have set the attribute, at the time of revalidation in the form bean, it is taken as a parameter to that validation method.

I hope this gives you a better?idea?for your question.
