The link you have provided, points to at .jar file. I am not that familiar with the Blackberry Java file descriptions, but I believe that .jar files relate to programs to be downloaded OTA. Someone correct me if I am wrong. You might want to research this, or ask in the Aftermarket S/W forum how to convert a .jar file to a .cod and a .alx file for installing using app loader. Or you might just try to install it OTA directly.
Hope this helps
