hi everybody, i have rfid card and i want to read-write operations (also many other op that are defined on card header). there is a dll (RR9000.dll) file for rfid card and a header file (RR9000.h). I want to use this dll on java application but don't know . I have used jni before, but this time all situations are different. Because dll is not prepared by native headers. Please help me.
