The JAVA device generates
                     output for the Graph, Map, Tile, and Contour applets. These applets
                     provide user interactivity in all of the supported Web browsers. If
                     you do not need interactivity, then use the JAVAIMG device, as described
                     in  Developing Web Presentations with the JAVAIMG and ACTXIMG Devices, or
                     use the PNG device, as described in  Developing Web Presentations with the GIF, JPEG, SVG, and PNG Devices. 
            Note: The
               JAVA device does not support character values on the response axis.
               When generating plots with the JAVA device, at least one variable
               must be numeric. When a numeric value is specified for the category
               axis and a character variable is specified for the category axis,
               the axis values are swapped in order to place the numeric value on
               the category axis. If both values are character values, the plot is
               not generated.
