| /** |
| * Widget that places a powered-by-Apache message on the page. |
| * |
| * <p> |
| * The variable it resolves is <js>"$W{PoweredByApache}"</js>. |
| * |
| * <p> |
| * It produces a simple Apache icon floating on the right. |
| * Typically it's used in the footer of the page, as shown below in the <c>RootResources</c> from the examples: |
| * |
| * <p class='bcode'> |
| * <ja>@Rest</ja>( |
| * path=<js>"/"</js>, |
| * title=<js>"Root resources"</js>, |
| * description=<js>"Example of a router resource page."</js>, |
| * widgets={ |
| * PoweredByApache.<jk>class</jk> |
| * }, |
| * htmldoc=<ja>@HtmlDoc</ja>( |
| * footer=<js>"$W{PoweredByApache}"</js> |
| * ) |
| * </p> |
| * |
| * <p> |
| * It renders the following image: |
| * <img class='bordered' src='doc-files/PoweredByApacheWidget.png'> |
| * |
| * <ul class='seealso'> |
| * <li class='link'>{@doc juneau-rest-server.HtmlDocAnnotation.PredefinedWidgets} |
