Ok. Well I have tried using the setProperty tag with property="*", but it
had no effect whether left out or not. What I'm talking about is say you have a
form, and just hit submit without entering any information in any fields. Take
this example (assuming you have an accompanying Bean to go with it):
<html>
<head>
<title> Test Page </title>
<jsp:useBean id="bean" scope="session" class="nameBean" > </jsp:useBean>
<body>
<p>The property name is null = <%= ( request.getParameter("name") == null ) %>
</p>
<form method="get">
<p>Name:<input type="text" name="name" size="20" value=" <jsp:getProperty
name="bean" property="name" /> "></p>
<p><input type="submit" value="Submit" name="submitBtn"><input type="reset"
value="Reset" name="ResetBtn"></p>
</form>
</body>
</html>
When this page is initially loaded, it will tell you that "The property name
is null = true". After hitting the submit button with NOTHING in the field, it
will tell you "The property name is null = false".
Sorry about the confusion. I really need to sit down and read the specs I
suppose, because I'm curious of when the Bean is created and why I'm having
trouble initializing Bean properties when it is created. :)
Thanks for you help though,
Brian
