I am using Windows 7 64bit. Currently, I have Netbeans 7.3 and jdk1.7.0_25 installed on my PC. I am trying to import JPCAP library to my project which I download from: http://sourceforge.net/projects/jpcap/. But when I try to use the library : import jpcap.*; (there's red color underline on "jpcap") and the error message is : package jpcap does not exist. Unused Import. Can anybody help me to figure this out. Thank's a lot.

一开始，JPCAP 不能在 64 位平台上运行（只有 32 位），要使用它，你必须下载 32 位 jdk 和 32 位 ide 并安装在你的电脑上。其次，要包含 JPCAP，您必须做一些事情，这个视频将非常有用。
