Re: JPL error

Hi Jerry,

May it be that when you changed the SWI version the jpl native library is not anymore in your path ?
I am not a Windows user, but it seems to me that libjpl.dll (or whatever it is called in Windows) should be in either your PATH environment variable or you should start Java specifying its location with the "java.library.path" parameter, like:

java -Djava.library.path="the_jpl_path"Can you verify that you are still pointing to the right location of this variable in your new swi installation ?

cheers,

Sergio
