OK, better in terms of what? What do you need that tcpdump/windump don't already provide? Why do you need to introduce Java into the system at all?

we need to implement network sniffer application using java, since the application may installed on windows and linux. Our team had looking around on internet and found those three application. we have no experience at all at developing network sniffer. We also got information in this forum that developing network sniffer using pure java is impossible, so those three may help us to solve our development challenge.

what we need to know is which of them provide more complete feature and easier to be customed with java. Another challenge is we haven't found any sample of java code which use one of those three sniffers, some code we found haven't give any good description.

may be somebody here is willing to help ?

thx
