| <p> A Web application is a group of HTML pages, JSP pages, servlets, resources | |
| and source file, which can be managed as a single unit. A Web archive (WAR) | |
| file is a packaged Web application. WAR files can be used to import a Web | |
| application into a Web server.</p> | |
| <p>In addition to project resources, the WAR file includes a Web deployment | |
| descriptor file. The Web deployment descriptor is an XML file that contains | |
| deployment information, MIME types, session configuration details, and other | |
| settings for a Web application. The Web deployment descriptor file (<filepath>web.xml</filepath>) | |
| provides information about the WAR file is shared with the developers, assemblers, | |
| and deployers in a J2EE environment.</p> | |
| <p>The Web development environment provides facilities for importing and exporting | |
| WAR files, using the following wizards: <ul> | |
| <li><ph>Import Resources from a WAR File</ph>, which requires that you to | |
| specify a Web project. You can use existing projects or create them as you | |
| use the wizard.</li> | |
| <li><ph>Export Resources to a WAR File</ph>, which requires only an export | |
| location and some optional settings</li> | |
| </ul></p> | |
