When you are ready to publish your Web application, you will need a server that will host it so users can access the Web site through the Internet; however, to test your Web site, you can use a test environment.
To use this tutorial, you must have an application server installed and configured. To verify that a server runtime environment is available, click , expand Server, and then click Installed Runtimes. You can use this pane to add, remove, or edit installed server runtime definitions. You can also download and install support for a new server.
To test the Web site on a server:
The server tools create the new server, start it, and open the page in the workbench internal Web browser. This may take a moment. In the Console view, you can watch the messages as the server tools start the server.
Once this process is complete, you can preview how the site will look and work once it is actually published to a Web server. Click the links, enter data in the forms, and see any dynamically generated content in the site that may not appear in Preview view. Also, if you wish to see your page in different Web browsers, you can copy the URL from the workbench Web browser into the browser of your choice.
You must stop the server before you can continue with the tutorial. If you leave the server running, you will see error messages when you continue with the tutorial. These errors appear because the server is connected to the sample database, preventing you from connecting to the database to change the information shown on the Web site.

at the top right of the Servers view. The server Status changes
to Stopping. You will see messages in the Console view while the server
shuts down. When the server Status in the Servers view changes to Stopped,
the server is stopped and you can continue working on the Web site.
