jsp create scripting variable like jsp:usebean does

Question

I would like to do something like <test:di id="someService"/`>
<% someService.methodCall(); %>

where <test:di
gets and instantiates a service bean and creates a scripting variable for use. similar to how jsp:usebean works for example <jsp:useBean id="someDate" class="java.util.Date"/>
<%
someDate.getYear();

%>

how do i make my own objects available as a scritping variable?

Answer 1

The way this is done in a Tag Library is by using a Tag Extra Info (TEI) class.

You can find an example here.

Answer 2

I think you're trying to write your own tag library.

Edit: As Garth pointed out, you want to use the TagExtraInfo class after you've defined your tag lib. http://www.stardeveloper.com/articles/display.html?article=2001081601&page=2
