Lightweiht Model 2 J2EE Framework for the HTTP Servlet position of the application.
NOT Meant to dictate the entire J2EE implementation.
Using Headless Mode in the Java SE Platform
This article explains how to use the headless mode capabilities of the Java Platform, Standard Edition (Java SE, formerly
referred to as J2SE).
Headless mode is a system configuration in which the display device, keyboard, or mouse is lacking. Sounds unexpected, but actually you can perform different operations in this mode, even with graphic
data. Let's say that your application repeatedly generates a certain image, for example, a graphical authorization code that must be changed every time a user logs in to the system. When creating an image, your application needs neither the display nor the keyboard. Let's assume now that you have a mainframe or dedicated server on your project that has no display device, keyboard, or mouse.
Web Tier to Go With Java EE 5
The first article in the "Web Tier to Go With Java EE 5" series, "Summary of New Features in
Java Server Pages (JSP) 2.1 Technology," introduced the new unified expression language. This fifth article of the series explains
The new #{?} syntax that the unified expression language supports
How #{?} expressions differ from ${?}expressions
Why the expert groups for JavaServer Pages (JSP) and JavaServer Faces technologies settled on two syntaxes instead of a single one
.
Using Indexed
property Forms
.Typically Used in "master-detail" type forms.
.for Example, a purchase order form (quality ,part, description, price).
.Or in an enrollment form.
.There are two fundamental ways to do this, one is handled better by Struts then the other.
Struts and JSF
* Java Server faces(currently under development in JRS-127)
* GOALS:
.Standard GUI component Framework for web application.
.Renderkits for different rending environments .
.struts will provide an intergration liabrary.
.require change to view layer and struts-conf.xml file only.
.plugs in to Requestprocessor APIs
Introduction of Struts
* Central controller mediates application flow.
* Controller delegates to appropriate handler
* Handlers are tied to model components
* Model encapsulations business logic
* control forwarded back through the controller to the appropriate view.
Struts Cross Reference
The purpose of this document is to provide a cross reference of an example application using the
Struts framework. This document displays where information from the
struts-config.xml file relate to Java Server Pages using the Struts tag libraries, and to Java classes extending both the
Action Form and Action classes.
