hi
Please help me.i am developing a java pgm to capture network packets using jpcap.i downloded jpcap and wpcap dll files.
My pgm is: - import jpcap.JpcapHandler;
-
import jpcap.Jpcap;
-
import jpcap.Packet;
-
public class sample implements JpcapHandler {
-
public void handlePacket(Packet packet){
-
System.out.println(packet);
-
}
-
public static void main(String[] args) throws java.io.IOException{
-
String[] devices = Jpcap.getDeviceList();
-
for (int i = 0; i < devices.length; i++) {
-
System.out.println(devices);
-
}
-
String deviceName = devices[0];
-
Jpcap jpcap = Jpcap.openDevice(deviceName, 1028, false, 1);
-
jpcap.loopPacket(-1, new sample());
-
}
-
}
-
when i run this pgm i got the following errors.
-
-
C:\Program Files\Java\jre1.5.0\bin>javac sample.java
-
sample.java:1: cannot find symbol
