由 末鹿安然 提交于 2019-12-25 01:59:38
问题 I want to make a college project for sharing of files among different computers. Usually we have same file, for example, a movie on different computers among a local network in our college. So I want to download a file in different parts from these computers simultaneously so that download will be fast. I am making this application in Java. What should I read? I am using JXTA for peer-to-peer (P2P) sharing. Is this possible using JXTA? 回答1: It is possible to do this in JXTA. You need to split

问题 P2p/Grid Computing seem like a promising concepts. JXTA looks like the only all in one framework for it. Is there a reason this field is so sparsely pursued? 回答1: I have lead the release of JXTA 2.6 and 2.7 - JXTA is not completely abandoned. Some people have posted patches on the 2.6 branch and it could easily be merged with the 2.7 branch. There are many reasons why people did not carry on participating to JXTA: Oracle did not follow-up on their duties regarding project governance, which

问题 Recently I was investigating p2p framework to use and I came across JXTA. Too bad, Oracle decided to dropped JXTA. Real shame for a nice software. Anyway the problem that I have is trying to start a node in rendezvous mode. NetworkManager manager = new NetworkManager(NetworkManager.ConfigMode.RENDEZVOUS,...); I'm getting a NoClassDefFoundError when I call manager.startNetwork(); The class it is having problem with is: org/jboss/netty/channel/socket/httptunnel/HttpTunnelClientChannelFactory

问题 I have two java applications running on two different machines in two different part of the world. The machines can be behind NAT (or not!). The applications are supposed transfer some data (<500kb). We do have a server, which can do everything (like providing ip address of the peers) but the data from the applications must always be transferred peer-to-peer. The data can not be routed through the server. Do I have to deal with firewall mess? Do I have to set port forwarding? Are JXTA or

The peers should be able to find each other in a group and send direct messages as well as propagate messages. What would a simple hello world type of application look like that meet these requirements? I created this question with the intention of supplying a tutorial like answer, an answer I tried very hard to find two months ago when starting to look at JXTA for a uni
