ECS is great when you are generating data programmatically--you can
write code that generates HTML/XML as it traverses some structure.
Thereare a variety of good template systems which you can use in the
other case--where you basically know what the page should look like,
and you want to drop some dynamic content into it.
One such framework is WebMacro (which is free), which introspects
objects to determine what information it could pull out (ie: bean style).
http://webmacro.org/
So you would create a template like this:
<html><head><title>$title</title></head><body>
<h1>Customer: $customer.Name</h1>
Outstanding balance is $customer.Account.Balance
</body></html>
This template gets compiled into an efficient form and shared between
servlets; thus it is what Luther called a shared object.
You use it like this:
Customer cust = ...;
context.put("title","Customer Account Balance");
context.put("customer", cust);
And WebMacro takes care of figuring out how to extract the required
information; in this case perhaps by calling
$customer.Name --> Customer.getName()
$customer.Account.Balance --> Customer.getAccount().getBalance()
Of course you can also loop through lists of customers, conditionally
include stiff, and so forth,
