Deploying web UI framework extensions
After you customize an existing screen using the Extensibility Workbench or create a new screen using the Designer Workbench, you must deploy your changes in the application. You can use either Java™ Server pages (JSP) or JavaScript Builder (JSB) files to deploy Extensibility Workbench changes. To deploy Designer Workbench changes, you must use a Java Server page.
A JavaScript Builder file contains JavaScript library/package definitions. The Web UI Framework provides programmatic control over this library with differential extensibility.
If minification is required, the directory structure in the <INSTALL_DIR>/extensions/<app name>/webpages directory changes slightly.
