Java抓取数据包出错

blizzardbr

import jpcap.Jpcap;
import jpcap.JpcapHandler;
import jpcap.Packet;

public class JpcapTip 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[i]);
                // }

                String deviceName = devices[0];
                Jpcap jpcap = Jpcap.openDevice(deviceName, 1024, false, 1);
                jpcap.processPacket(-1, new JpcapTip());

                Packet packet = jpcap.getPacket();

                System.out.println(packet.toString());

        }
}


为什么在jpcap.getPacket();出现下述奇怪的错误呢？

1.5.0_08-b03，升级一下JDK吧，或者把hs_err_pid756.log的内容精简上来看看。

JDK的问题,是跑一次就报一次错,还是偶尔发生的~

谢谢各位兄弟，我的jdk是1.5.0_08的，应该不是jdk的问题。我的JPcap用的是在Sourceforge.net里下载的jpcap1.4，有点老，不知道是不是这个问题？

hs_err_pid756.log的内容是这样的：

汗，没弄过Jpcap
换个操作系统与JDK再试试吧。

beichihwfs

哦 顺便说一句   现在Jpcap好像有两个版本，http://jpcap.sourceforge.net/上面写

Jpcap development is hosted at http://www.sf.net/projects/jpcap，我把jpcap-0.5.1下载下来以后，发现里面的F&Q里面有一句话：

Q: Is this Jpcap related to the Jpcap on sourceforge?

A:  No. They are independently developed, and thus are totally different products.


靠   妈的  我真是糊涂了~~~~~~~~`
