I'm still working on proper jNetPcap release. Since jNetStream is layered on top of jNetPcap, its been put on the back burner until jnetpcap-1.2 is released. The jnetstream-3.0a1 is workable, for those brave enough to try it. jNetStream has fully functional and tested capture file manipulation. You can edit, index, slice and dice different types of capture files to your heart's content. Its very very fast and efficient. I can't wait to finish jnetpcap and restart work on jnetstream. jNetStream provides a much higher and nicer public API then jnetpcap which is more low level stuff. jNetStream also replaces libpcap's offline captures (reading from files) since it provides a lot better implementation of it. I realize that many people are asking for jnetstream and I wish I could speed up my work. We will get there though.
