Is it possible to use JNI (Java Native Interface) in Applets, has anyone tried?
You can use the JNI from the applet, just remember that the applet is running on the client, so the JNI will access the client for the "NI" part.
I'm not very good at JNI, but I have a googled link that can help you. It contains information on accessing the DLL with the JNI. Take a look: Calling a DLL from an applet via JNI
