Struts - Form Validation, Form-Bean and Form-Action

Hi,

Please look here:

http://jaggybala.clawz.com/CalendarTool/ShowList.html

At present i have 3 JSP's, 2 Form-Bean and 2 Form-Action as follows:

JSP Form-Bean Form-Action
------------ ----------------- -------------------
FilterList.jsp FilterForm.java FilterAction.java
RegisterList.jsp RegiterForm.java RegisterAction.java
ShowList.jsp --- ---

ShowList.jsp includes FilterList.jsp and RegisterList.jsp and shows List of Members below as shown.

I am doing Validation in FilterAction.java (for FilterList.jsp fields), RegisterAction.java (for RegisterList.jsp fields) and forward( & re-direct) both Form-Action's to ShowList.jsp so that if there are any validation errors, it should display in the ShowList page.

But, i have some problems and difficulties in doing so.

I think instead of above designing, there should be an easy/efficient way of doing this. Is it possible to write One JSP that has 2 FORMS along with proper Validations and Actions ?

If so, please suggest me. Thanks.

why don't you validate data by using struts framework? As you explain me that you validate it by Form-Action, I suggest you to find how to validate data in struts.

becuase I don't have enogh time to give you some useful code, but I have some clue for you to get start.

in the Form-Bean there will be validate() method which will call automatically by struts when you submit data from jsp if there are some error you can specifie target action or jsp to redirect to.

we just implement this method in Form-Bean

public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request)
{
ActionErrors errs = new ActionErrors();

if (condition) {
errs.add("zipcode", new ActionError("invalidZipCode"));
}
if (condition) {
errs.add("phone", new ActionError("phoneInvalid"));
}

return errs;
}

and tell struts will validate data when they create this form bean if there is no error so they pass to action-from
but If there are some errors they will redirect request to the error page that I configured.

In error page I can use some taglib to access this error and display it.

I can not remember for exactly detail now. But If I am free, I will be back here to explain you more.

invalidZipCode,phoneInvalid

this I use in ActionError("....")
is a key for lookup message from message repository. So It would be useful if we deploy application in another locale, we just create a new message repository for that country.
