4.2.1Web development tools

The professional Web development environment provides the necessary tools to develop sophisticated Web applications consisting of static HTML pages, JSPs, servlets, XML deployment descriptors, and other resources.

Wizards are available to generate running Web applications based on SQL queries and JavaBeans. Links between Web pages can be automatically updated when content changes. There are also tools for creating images and animated GIFs.

The Web development environment bring all aspects of Web application development into one common interface. Everyone on your Web development team including content authors, graphic artists, programmers, and Web masters, can work on the same projects and access the files they need.

Such an integrated Web development environment makes it easy to collaboratively create, assemble, publish, deploy, and maintain dynamic, interactive Web applications.

The Web development tools provide the following features:

Support for latest Web technology with an intuitive user interface

Advanced scripting support to create client-side dynamic applications with VBScript or JavaScript

Web Art Designer to create graphic titles, logos, buttons, and photo frames with professional-looking touches

Animated GIF designer to create life-like animation from still pictures, graphics, and animated banners
