jNetPcap is a Java library that is a wrapper around the popular libpcap from tcpdump.org. What makes this library unique is that it is a comprehensive wrapper around the entire libpcap library. jNetPcap uses the same style of API as libpcap.
This is a maintenance release. Packages are provided for Fedora Core 8 (Linux), Debian 4 (Linux), and Win32 (WinXP/Vista). There are no bugfixes, since no bugs were reported.
