Built-in Web Application Templates and Options
In the Web Application Project Wizard, you select a Web application template which dynamically modifies the rest of the wizard and controls what content is generated for your Web application. You will also choose Web application options, application initial content, and an initial file template using the wizard.
You can also change most Web application options after the project is created, by
selecting File ![[arrow]](../../images/arrow.gif){kind=icon}
Web
Application Properties.
This document describes the purpose and relation of these choices, and what the result will be for the various selections you can make. The built-in templates and options can be extended so you can provide your own content choices in the wizard, resulting in user-specified content being generated for the Web application. For more information about the example templates, see Web Application Example Templates.
Standard Web Application Templates
The Web application template defines the overall content of the Web application. Exactly one Web application template must be chosen. Once the wizard is finished, template settings become permanent for the project.
What a Web Application Template Controls
The Web application template for the project can specify any combination of the following actions:
- Add additional pages to the wizard.
- Add content to the Web application that is created.
- Add Web application options that appear as check boxes in the Options list that is displayed on the Web Application Options page of the wizard. Also, it can specify which options should be checked by default, and which are required (cannot be un-checked).
- Add initial content choices to the list displayed in the Web Application Initial Content page of the wizard.
- Add one or more component palettes to the project.
- Modify project properties.
- Modify the project.

Standard Web Application Options
Web application options represent content that may or may not be present. Unlike Web application templates, zero or more options can be selected; however, the governing template may specify that one or more options are required. One option may also require another.
Also unlike Web application templates, some options may be added to the project at a later date, and options that are not required may be removed. However, as shown in the table above, the options available are determined by the Web application template. For example, the Struts tag library option can only be added to a Web application defined with a Struts Web application template.
What a Web Application Option Controls
Each Web option for the project can specify any combination of the following actions:
- Add additional pages to the wizard.
- Add content to the Web application created.
- Make other Web application options required, which will be automatically checked when this option is checked.
- Add initial content choices to the list displayed in the Web Application Initial Content page of the wizard.
- Add one or more component palettes to the project.
- Add tag libraries to the list of "enabled" tag libraries.
- Modify project properties.
- Modify the project.
