The architecture of JViews Gantt JSF technology

Presents an overview of the architecture of JViews Gantt JSF technology.

• About support for JViews JSF technology

Describes JViews Web application support based on JavaServer™ Faces (JSF) technology.

• Servlet and component classes

Identifies servlet and component classes for generating the visual representation of the component.

About support for JViews JSF technology

The Web application support based on JavaServer™ Faces (JSF) technology consists of:

• The tag library (a set of JSP™ tags)

• A Java™ API

• An AJAX based JavaScript™ library

The JSP™ tags are used to build JSP pages. Each tag represents a component and has a set of attributes for configuring the component.

Not all the components have a visual representation. For example, an interactor is intended only to be set on a view and has no visual representation.

When a tag is processed by the JSP engine, it is compiled into Java code that is executed to produce the page content. The tag library produces JavaScript objects. Each object can be referenced by JavaScript code and can be modified on the client side without a server round-trip.

See the Release Notes for the Web browsers and versions with which the JViews Gantt JSF components are compatible.

JViews Gantt JSF component set

The JViews Gantt JSF component set includes:

• A Gantt chart view

• A Schedule chart view

• A set of interactors

• A pop-up menu

JViews Charts JSF component set

The JViews Charts JSF component set includes:

• A chart view

• A chart overview

• A chart legend

• A set of interactors

• A pop-up menu

JViews Framework JSF component set

The JViews FrameworkJSF component set includes:

• A view

• An overview

• A pan tool

• A zoom tool

• A set of interactors

Servlet and component classes

JSF components in JViews Gantt use servlet technology to produce the images that are the visual representation of the component on the client side. Dedicated servlet, servlet support, and components are available to help create an application.
