What is Framework?

In information systems environment, a framework isa defined support structure in which other softwareapplications can be organized and developed.

A software framework is a reusable design andbuilding blocks for a software system and/orsubsystem

What is Framework? (cont.)

In an object-oriented environment, a frameworkconsists of abstract and concrete classes.Instantiation of such a framework consists ofcomposing and subclassing the existing classes

Software frameworks rely on the HollywoodPrinciple: "Dont call us, well call you."

Why we use Framework?

The software frameworks significantly reduce theamount of time, effort, and resources required todevelop and maintain applications.

Why we use WAF?

Virtually all web applications have a common set ofbasic requirements, such as user management e.g.,secure user login, password recovery), groupmanagement, and access authorization.

A Web Application Framework usually includes allthese functionalities, refined through hundreds ofproduction deployments, freeing developers to

focus on the needs of their specific application.

Request based frameworkis basically a webframework that gets user's request then determinewhat the system should do and give back theresponse back to the user. So basically as you can

see, the flow is pretty much linear.

Hybrid Framework: The framework combines bothrequest-based and component-based frameworksby taking control of the entire data and logic flow ina request-based model.

A Request-based Framework is very close to theoriginal CGI specification.

It uses controllers and actions that directly handleincoming requests.

Each request is essentially stateless.

Struts was originally developed by CraigMcClanahan and donated to the ApacheFoundation in May 2000.

Struts has been a de facto framework with a strongand vibrant user community.

Struts (cont.)

Struts uses and extends the Java Servlet API toadopt the "Model 2" approach, a variation of theclassic Model-View-Controller (MVC) designpattern.

Jave Server Faces (JSF)

JavaServer Faces (JSF) is a server-side user interfacecomponent framework for Java-based Webapplications.

JSF contains an API for representing UI componentsand managing their state; handling events, server-side validation, and data conversion; defining pagenavigation; supporting internationalization and

accessibility; and providing extensibility for all thesefeatures

Embedding HTML

HTML within JSF tags does not workwithout f:verbatim

html

Use Exadels htmLib.jar instead


69/86

Components and Renderers

Building custom components

No simple task

Separate the renderer (easy to do)


70/86

Validation

If validation or conversion fails nothinghappens

Action method bindings do not execute

Page just comes back

Most common JSF forum post

Use h:message orh:messages


71/86

Bundle Keys x.y.z

Resource Bundles are loaded as maps #{bundle.userslastname}works

#{bundle.user.name.last} fails

#{bundle[user.name.last]} works

For properties:

#{bean.user.address.street}works

Tool Support

Most IDEs have limited JSF support

The following IDEs provide the ability todrag and drop components onto apage:

IBM WSAD

Borland JBuilder

Oracle JDeveloper

Sun Java Studio Creator

Netbeans too

Eclipse* IntelliJ* JBuilder Netbeans*

IBM WSAD Studio Creator JDeveloper Notepad**
