Create a Modal Dialog box containing a form using struts2

In my application I have a part of form which should allow details of a n number of persons. i.e,

Field1 Field2 field3

now a button Details of persons

on button click it open a modal dialog box containg a form with 3 fields about person.When I click save. the details of persons sections should update...This should repeat on every button click.. I also need validations for fields on modal dialog box.

开发者_JAVA技巧Th data entered for field1,2,3 should remain same during the process..
