...and why does this not work:

------------------------------------------------------
<%@ page import="questiondb.ResponderBean" %>

<jsp:useBean id="responderBean" class="questiondb.ResponderBean" scope="session">
<jsp:setProperty name="responderBean" property="*"/>
</jsp:useBean>

<html>
<head>
<title>Quick Test!</title>
</head>
<body>
<form action="PersistenceServlet" method="POST">
Name: <input type="name" size="30"><br>
Email: <input type="email" size="30"><br>
<br><Br><input type="submit" value="Post it!">
</form>
</body>
</html>
---------------------------------

I bind it to the session, but when I hit my servlet, the beans entries are null (not the bean itself however). Why are name and email not populated?

When does the setProperty thing actually do its stuff?

Thanks,
Rog

errata: above - first mistake is:

<input type="text" >>>name<<<="name">
<input type="text" >>>name<<<="email">

Anyway, I tried that, and still get nulls for the values.. So the question still stands if someone can help me.

Thanks!

Unless I am mistaken, I think the idea is to do a HTTP POST to a JSP with these elements, then we can do the setProperty thing in the JSP we've sent the data to.... is this as dynamic as it gets? It seems annoying having a second 'receiver' JSP... can't we put everything in the same JSP?

When you put a setProperty tag in the body of the use bean tag, it will only get called the first time the page is called. Usefull for initializing.

Take it out of the body and it will get excecuted every time.
