Where to keep “form” value

[jacob deiter]

1) I design a JSP page (A)which contains drop list and text fields, each fields having values in it
2) When I navigate to next page(B) and coming back to this screen
3) All the values in its(page A) will disappears
4) To main the data in the page A, even I came back to this page(A) from Page (B),what I have to do???

Unless you use a web-framework which does this automatically for you, you need to do a bit of tedious work.

1) The parameters should be stored in the session.
2) Your A.jsp should pre-insert these values.

e.g.

<input type="text" name="name" value="${sessionScope.name }" />

I hope by "come back" you don't mean coming back by clicking browser's back button or pressing backspace or doing HTML DOM's history.back
