Additional Libs for JLink App

Hi guy, i'm facing a problem adding additional libraries to my jlink application. Actually just the .jar files. To make myself a bit clearer: i've got a protk.dat like the following

c9521b1c68

within this app im calling a class from the swingX libraries (JXFrame).

c9521b1c68

My problem is now, that proE doesnt start the app if only the swingX.jar is located within the ./apps/jlinkapp/build folder. But as soon as I extract the "org" folder from the jar and put it directly into the build folder everything works fine. Is there a way to tell jlink in which .jars to look? Regards
