JPCAP是一个开源库从Java应用程序的网络数据包捕获并发送。它提供的设施：
捕获原始数据包从电线。
脱机文件保存捕获的数据包，读取捕获的数据包从一个脱机文件。
自动识别数据包类型，并生成相应的Java对象（用于以太网的IPv4，IPv6中，ARP / RARP，TCP，UDP和ICMPv4报文）。
根据用户指定的规则过滤数据包调度给应用程序之前。
原始数据包发送到网络
Jpcap是基于 libpcap的/ WinPcap的在C和Java实现。JPCAP已通过测试微软Windows（98/2000/XP/Vista的），Linux操作系统（Fedora，Ubuntu的的）的Mac OS X（达尔文），FreeBSD的，和Solaris。
JPCAP is an open source database from a Java application to capture and transmit network packets. It provides facilities: capture the raw data packets from the wire. Offline Files save the captured packets, read the captured data packets from an offline file. Automatic identification packet type, and generates the corresponding Java objects (for Ethernet IPv4, IPv6 in, ARP/RARP, TCP, UDP, and ICMPv4 packets). According to the rules specified by the user to filter data packets to the application before dispatch. Original packet is sent to the network Jpcap libpcap-based/WinPcap in C and Java. JPCAP has been tested Microsoft Windows (98/2000/XP/Vista' s), Linux operating system (Fedora, Ubuntu' s) for Mac OS X (Darwin), FreeBSD' s, and Solaris. (2013-06-13, Java, 40KB, 下载49次)
