JXTA™ technology is a set of open protocols that allow any connected device on the network ranging from cell phones and wireless PDAs to PCs and servers to communicate and collaborate in a P2P manner.

JXTA peers create a virtual network where any peer can interact with other peers and resources directly even when some of the peers and resources are behind firewalls and NATs or are on different network transports.

• Interoperability - across different peer-to-peer systems and communities
• Platform independence - multiple/diverse languages, systems, and networks
• Ubiquity - every device with a digital heartbeat

• Find peers and resources on the network even across firewalls
• Share files with anyone across the network
• Create your own group of peers of devices across different networks
• Communicate securely with peers across public networks
