J2EE Example

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.

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.

Java DMK Java Dynamic Management Kit (Java DMK) is a Java technology based toolkit that allows developers to rapidly create smart agents based on the Java Management Extensions (JMX) specification. T Java Dynamic Management Kit (Java DMK) is a Java technology based toolkit that allows developers to rapidly create smart agents based on the Java Management Extensions (JMX) specification. T he power of the JMX framework is that it supports multiple protocol access to management information residing in the agent. he power of the JMX framework is that it supports multiple protocol access to management information residing in the agent. The latest release of Java DMK, conforms to JMX v.1.2 and JMX Remote API 1.0. The JMX specification defines a three- level management architecture: The latest release of Java DMK, conforms to JMX v.1.2 and JMX Remote API 1.0. The JMX specification defines a three- level management architecture: The instrumentation level makes resources manageable as Java objects The instrumentation level makes resources manageable as Java objects The agent level exposes these objects for management The agent level exposes these objects for management The distributed services level allow remote access and security The distributed services level allow remote access and security

Why use Java DMK Device vendors and application developers can use any technology they want: as long as management applications communicate through a Java dynamic management agent, they can access any resource Device vendors and application developers can use any technology they want: as long as management applications communicate through a Java dynamic management agent, they can access any resource Management services deployed in agents can interchange resources dynamically, allowing new services to be downloaded and plugged into smart agents as and when they become available Management services deployed in agents can interchange resources dynamically, allowing new services to be downloaded and plugged into smart agents as and when they become available
