Including Source Files in the WAR File
By default, the .java files are not added to the WAR file and properties screen, select Build -> Packaging. Edit the Exclude From WAR File box and remove **/*.java,.
Additional features will be added to a web application by using jar files. Download the jar file to your system, then right-click the Libraries folder and select Add JAR/Folder.
Whenever the project is cleaned and built (select Clean and Build from the Build menu), a Web Archive (WAR) file is created. This WAR file is actually a ZIP file that contains the web application. The WAR file contains a web application that has a standard format. The WAR file is located under the Files tab in the dist folder.
