I have a block of JSP code that needs to be used in several places (basically a widget that several pages use). What’s a good way to modularize this? I’d rather not put it in an object since string manipulation of HTML gets ugly. Using <%@ include file='foo.jsp'%> is problematic because we wind up having implicit global vars.
You can create a simple tag and use it anywhere you want your widget. A tag is a reusable object that you can use in any of your JSP’s.
