I have made a struts web project.

The problem I am having is when a user enters the values into the form and
submits it.
If any one of the user inputted values are invalid, then I get the action
to forwards back to
the input page. In doing so all the values that the user inputed in the
form are lost.
Is there any way in which these values can be stored, apart from cookies.
