wireshark是基于winpcap或者libpcap的应用软件。如果你想自己开发抓包类的，应该用winpcap的api之类的。winpcap网站上faq提到这个问题了

Q-12: Does WinPcap work with Java?
A: We do not directly support Java. However you can find a Java wrapper at netresearch.ics.uci.edu/kfujii/jpcap/doc/index.html 和 jnetpcap.com /.

贴的代码格式全乱了，我传了个附件。
里面的网址匹配还不完美，可以改进。
欢迎探讨。
jPCAP在JAVA中，并非一个真正去实现对数据链路层的控制，而是一个中间件，JPCAP调用winpcap/libpcap，给JAVA语言提供一个公共的接口，从而实现了平台无关性。
firefox的fidder插件 Java程序需要设置proxy才能生效：
String url="url address";
Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress("127.0.0.1", 8888));
URL serverUrl = new URL(url);
HttpURLConnection conn = (HttpURLConnection) serverUrl.openConnection(proxy);
以下是完整参考代码：

Proxy proxy = new Proxy(java.net.Proxy.Type.HTTP,
new InetSocketAddress("127.0.0.1", 8888));
URL serverUrl = new URL(url);
HttpURLConnection conn = (HttpURLConnection) serverUrl
.openConnection(proxy);
conn.setRequestMethod("GET");
conn.addRequestProperty("Accept-Charset", "UTF-8;");
conn.addRequestProperty("User-Agent",
"Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2.8) Firefox/3.6.8");
conn.addRequestProperty("Referer", "");
conn.connect();

conn.getInputStream()));
StringBuffer buffer = new StringBuffer();
String line = reader.readLine();
while (line != null) {
buffer.append(line).append("\r\n");
line = reader.readLine();
}
reader.close();
conn.disconnect();
System.out.println(buffer);
} catch (Exception e) {
e.printStackTrace();
}

上面的那个是用流写的 但是也可以用超链接下载
你写上文件的路径就可以了
