Example for setting a page title in JSP:
This is assuming that the title parameter is passed as part of the url. Wushutwist
Code:
<html>
<head>
<title><%= request.getParameter("title") %></title>
</head>
</html>This is assuming that the title parameter is passed as part of the url. Wushutwist

What you are doing in the div? Could be anything, that is why I left it out. It is all the same concept though, get the parameter and place it on the page. Wushutwist

I'm simply placing text in it. I've tried setting it using the div id and various attribute names for the body content, but I haven't been succefull. Here's a some xamples of what I've tried:
.
.
<div id="heading_div" align="center"> </div>
.
.
<script language="JavaScript">
document.forms[0].heading_div =
"First attempt."
document.forms[0].heading_div.body_content =
"Second attempt."
document.forms[0].heading_div.text =
"Third attempt."
</script
Note: I try only one of the 3 samples at a time. I've put them all in one script tag for brevity.

Simple Example:
Assuming divBody is the parameter passed. This is the simplest form of web programming. There are many many more things you can do with JSP and Servlets beyond passing everything around in Querystrings. Wushutwist

Well then you kind of lose the purpose of using JSP because then you are left to use something like Javascript. Doesn't make any sense. Taglib is essentially jsp anyways. I don't understand why you would put this kind of restraint on yourself. It is not like you are embedding huge convuluted chunks of Java code in your documents. Wushutwist

But you are still putting Java in your html pages... just all the way down at the bottom. So the two options you are considering are:
1) Place a tiny bit of Java code mixed in with HTML (purely for presentation purposes).
2) Place a bit more Java code mixed with a convoluted javascript at the bottom of the page to do a simple routine.
Disadvantages to 1: Mixture of Java and HTML but no Java logic to drive the page.
Disadvantages to 2: Still a mix of Java and HTML, throw in a bit of javascript and now you have a maintence nightmare.
With the exeception of Custom Tags, it seems number 1 is the only logical answer. BTW, the Custom Tag for this purpose would be trival to write and if number one is definitely out (for whatever reason) I suggest going with the Custom Tag solution.
