Java SE (Java Platform, Standard Edition)

I have a jnlp file for an application that looks similar to the one below. I notice after downloading that the desktop shortcut created uses the Windows javaws.exe rather than Sun's. I see this in the properties of the shortcut:

C:\WINDOWS\system32\javaws.exe "C:\Documents and Settings\Lynn\Application Data\Sun\Java\Deployment\cache\6.0\62\47dec6fe-1c6e0861"

I would expect it to use the javaws.exe in C:\Program Files\Java\jdk1.6.0\bin. Is there a way to set this?
