Apparently Struts doesn't think that the declaration of the CC field and its accessor methods meet the requirements of a bean. What do the field and method declarations look like?

thanks i got it,

hmm the problem was i havn't declared setter and getter for credit card filed in FormBean class

now it is working well

but i have one doubt
but here i've seen it by the help of debug statements(sop),after submitting the form in jsp the control goes to Form class(bean) and then to action class(controller)

but according to MVC after jsp the control must go to controller where the request is handled and according to the request it must forward to the bean

It sounds like you could use some time with a decent book on Struts. Your action class is just part of the "controller" portion of your Struts application. It is the StrutsServlet that will handle the request and pass off processing to the RequestProcessor. These two classes are also part of the controller. The RequestProcessor will only call the execute method on your action if the form passes validation.
