your issue is not that GF does not find the jar file.... in fact it DOES find it.
But your error is "MethodNotFound"
in other words.... the class (inside the jar) gets found, but the method you are calling does not exist. You likely have used a different (newer ?) version of the library then what you have deployed to glassfish.
solution: remove all copies you added, and add the copy you used to compile against
