'load_capabilities' tag 

The 'load_capabilities' tag is needed for those who intend to use the conditional tags in the JSTL with WALL as in the example below:

<c:if test="${capabilities.gif}"> 

Loading the capabilities is sort of expensive the first time, so it's wise to avoid that operation unless you know you need it. 

Invoking the load_capabilities tag will make the following variables available for your scripting:


${capabilities.'capability_name'}  =  wurfl capability

${wall_markup}                     =  xhtmlmp, wml, chtml

${brands}                          =  list of device brands

${devices.'brand_name'}            =  list of devices grouped by brand

${device_id}            =  WURFL device_id (debugging purposes)
