Error while using jpcap java library

Question

I am using jpcap library to read network traffic and getting exception while executing the following code:

NetworkInterface[] devices = JpcapCaptor.getDeviceList();

Following is the error message:

Exception in thread "main" java.lang.UnsatisfiedLinkError: jpcap.JpcapCaptor.getDeviceList()[Ljpcap/NetworkInterface; at jpcap.JpcapCaptor.getDeviceList(Native Method) at nav.weka.first.JcapTest.main(JcapTest.java:16)

Is anything wrong with the jpcap.dll???

Answer 1

Did you install winpcap ? http://www.winpcap.org/

Answer 2

Your application is not finding the DLL. Check that it is on your PATH (not CLASSPATH).
