Is it possible to use validator plugIn with DynaActinForm in struts? If yes, can any body provide example for that? I tried but didn't succeeded.

which one is better Action Form or Dyna Action

Posted by krishna on Thursday, 01.17.08 @ 17:44pm | #45447

all the examples are worth learning. In DynaActionForm is there any internal method called saveErrors(HttpServletRequest, ActionMessages).

If Not please, in Struts DynaActionForm section explain saveErrors method in action class AddressDynaAction.

Thanks & Regards,

I think action classes are not singletone classes.
only actionservlet(all serlets) is the singletone class

Hi, I am facing a problem in retrieving a jsp using struts framework. I am getting the error "Form bean not specified on mapping for action: "/SetNewPassword". struts config is as below:

I have defined 2 form beans and 2 action mappings. The "/SubmitLogon" action works fine, but "/SetNewPassword" is giving "Form bean not specified on mapping for action". Could any one help me resolve this problem.

I had a doubt regarding in getting Date value from the Dynaform and assigning it to the database by convert it into required format

Posted by vineela on Saturday, 03.10.07 @ 22:29pm | #11338

Excellent MR Ramaswamy articles are fentastic

Posted by sundaram on Friday, 03.9.07 @ 12:14pm | #11228

This works great, if one knows the number of fields that will be displayed on the form. How would one code for a variable number of field and their values being retrieved from a DB.?? Particularly if one is trying to validate the values once a user has modified them.
Any help would be very much appreciated. I have looked @ several options, but none of them seem to work.

TIA

Hello
I am not able to display error messages in the DynaAddress.jsp
Errors are getting added to errors object in AddressDynaAction.java file since errors.size is 3
But not getting displayed in jsp.
I tried the alternative solution provided by Mr.Daniel for Mr.Ravi's query, but still no change in the result.
Kindly help.

In dynaActionfrom only suports String only,
or can we use other like Integer and Collections
like arraylist

Posted by JP on Tuesday, 01.16.07 @ 11:10am | #3592

Ravi:
If you are using Struts 1.1 you should replace the above code with the following

//Create object of ActionMesssages
ActionErrors errors = new ActionErrors();
//Check and collect errors
if(((String)addressForm.get("name")).equals("")) {
errors.add("name",new ActionError("error.name.required"));
}

if(((String)addressForm.get("address")).equals("")) {
errors.add("address",new ActionError("error.address.required"));
}

if(((String)addressForm.get("email")).equals("")) {
errors.add("email",new ActionError("error.emailaddress.required"));
}
//Saves the error
saveErrors(request,errors);

Remember taht the use of ActionMessages to hold error messages instead of ActionErrors is rather unfortunate. In earlier versions of Struts, it would have indeed been ActionErrors, but later versions have deprecated the use of ActionErrors everywhere except as the return value of validate() in ActionForm.

Its a very good example and very simple to understand.
