JSP, can it work similar to yield, layout, content_for in Ruby/Rails/Erb

Question

I am trying to figure out how to most effectively reuse JSP code. I love the way Rails/erb works in that way ... with yield, layout, content_for

Example:

Answer 1

I'm not familiar with what yield and content_for provide, but JSP tag files allow you a more robust way to template pages than JSP includes.

Example:

layout.tag

<%@ tag body-content="scriptless" %>
<%@ attribute name="pageTitle" required="true" type="java.lang.String" %>



    


    

An individual JSP

<%@ taglib prefix="z" tagdir="/WEB-INF/tags" %>

    
Hello, JSP!

Just place your layout.tag in the /WEB-INF/tags directory. You can use any available prefix you want, I just used "z" for the example.
