The Hello application is contained in a Web ARchive (WAR) file in the samples/quickstart directory. Packaged applications can also be in the form of a Java ARchive (JAR) or Enterprise ARchive (EAR) file.
Alternatively, you can download this application from https://glasfish.dev.java.net/downloads/quickstart/hello.war.
Copying to a domain’s autodeploy directory lets you put a pre-packaged application into use immediately, with minimal effort.
Find as-install/samples/quickstart/hello.war or download from https://glasfish.dev.java.net/downloads/quickstart/hello.war.
Copy hello.war to the as-install/domains/domain1/autodeploy/ directory.
On Windows, you can create a shortcut to the autodeploy directory on your desktop, and then drag and drop the hello.war file onto the shortcut.
When the server has finished deploying the application, it creates a file named hello.war_deployed in the autodeploy directory. Depending on the speed of your system, the process can take a few seconds. Until that file appears, a 404-File Not Found error occurs when you try to visit the application page.
Access this URL to visit the application page: http://hostname:HTTPport/hello.
You see the application’s first page, which prompts you to fill in your name:
Type your name and click Submit.
The application displays a customized response, giving you a personal Hello.
