Creating your first web application
Version 3.3
The ArcGIS Viewer for Flex ("Viewer") Application Builder enables quick and easy creation of new web mapping applications, as well as view and modify existing web applications. It is designed to make the process seamless without requiring programming or configuration file editing. The process of creating a new ArcGIS Viewer application using the application builder is as follows:
![]() |
The first time the application builder starts, it requires the following two parameters to be set:
- Web Server Base Folder
- This is the default location where web applications are created. The default value location for Windows is C:\inetpub\wwwroot\flexviewers.
- Web Server Base Folder URL
- The uniform resource locator (URL) base address to access your viewer applications in a web browser. The default value for Windows is http://localhost/flexviewers/.

Click the Save button to save your settings. The Application list panel appears and shows the applications associated with the ArcGIS Viewer for Flex Application Builder. If you do not have any existing web applications located in the specified directory, the list will appear blank. The screenshot below indicates multiple web applications in the default 'flexviewers' directory. Under the Actions column you may notice that you have the option to upgrade your existing applications to the most current version.

If you do not wish to open an existing web application, click the Create a new application button to start the process. Specify an Application Name for your new application. The Application URL address parameter updates to match the application URL.

Click Create. The application builder generates the appropriate files for your new application. When this process is complete, the main Application Builder user interface appears.
