Hello,
I have a jsp with various form inputs. The inputs are mapped to bean
properties. I want to start processing the form only after all the
submitted properties are set. To achieve this effect, I am specifying
a helper jsp as the form action in the jsp which submits the input.
Let's take login as an example.
in login.jsp:
...
<jsp:useBean id="loginHandler" class="LoginBean" scope="session"/>
...
<form method=post action=authenticate.jsp>
User name: <input type=text name=username>
Password: <input type=password name=passwd>
<input type=submit value="Submit">
</form>
...
in authenticate.jsp:
<html>
<%
loginHandler.processRequest();
%>
<%@ include file ="login.jsp" %>
</html>
If I process the 2 pages as they are, the "loginHandler" in the 2nd page
will be tagged as undefined parameter or class during page compilation.
What is the proper way to convey the sharing of this parameter.
Also, is this approach of using the form action in the first jsp to
ensure entry to backend processing only after setting necessary states
a valid way to go? Or are there better ways to go about it? (BTW, all
this similates the afterSet() used in ATG Dynamo.)
Thanks,
-Mary
