8. J2ME – Java 2 Micro Edition J2ME enables Java applications to run on small, resource- constrained computing devices (mobile phone, PDA). Java technology for handheld and embedded devices. Compatibility with J2SE is maintained wherever feasible. In fact, J2ME removes the parts of J2SE that are not applicable to constrained devices, such as AWT and other features. J2ME defines configurations and profiles. 2 Configuration CLDC – Connected Limited Device Configuration, Device with 160 – 512 KiloByte memory, Part of J2SE feature, prosesor 16 or 32 bit CDC – Connected Device Configuration Minimum memory 2 Mbyte, Full J2SE features, Prosesor 32 bit Profile : MIDP, FP, Personal, RMI Profile, PDA Profile.

14. JXTA You can use JXTA technology to create peer-to-peer (P2P) applications based on Java technology. You can use JXTA technology to create peer-to-peer (P2P) applications based on Java technology. JXTA technology is a set of open protocols that enable 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 technology is a set of open protocols that enable 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 network address translations (NATs) or on different network transports.
