I have 2 jsp pages.The field in one jsp must be automatically updated when a field in another jsp is entered or selected from a dropdown.

How can I do this using DTO

when the user modifies the value in JSP 1, update the value in the DTO. When the user loads JSP 2, read the value from the DTO. Any more questions?

If you are using struts framework then i think you can also do it with form beans.
