Once you finish creating the page, you need to deploy your page to be accessed by an URL. For that ONEWEB provides the Build & Download button in the Application menu.
When you click on the Build & Download, wait for a few moments for it to build all the pages in your application. Once it completes, a "Build succeed" message will be displayed, indicating that the build was successful. The files will then be exported as a zip file and will download to your machine.
To preview this page on the browser, you can use the URL: http://(IP Application server)/(ApplicationCode). In this case your applicationCode is 'DemoApplication'.
To deploy this web page to the real environment, users can copy the downloaded zip file to a web server like Apache or IBM HTTP Server and map the domain for the site. Now users access the web page through the domain URL.
