Java Technology

Java technology is a portfolio of products that

are based on the power of networks and the

idea that the same software should run on

many different kinds of systems and devices

J2SE (Java 2 Standard Edition)

Core Technology The essentials: Objects, strings, threads, numbers, input and output, data

structures, system properties, date and time, and so on.

Applets: The set of conventions used by applets.

Networking: URLs, TCP (Transmission Control Protocol), UDP (UserDatagram Protocol) sockets, and IP (Internet Protocol) addresses.

Internationalization: Help for writing programs that can be localized forusers worldwide. Programs can automatically adapt to specific locales andbe displayed in the appropriate language.

Security: Both low level and high level, including electronic signatures,public and private key management, access control, and certificates.

Software components: Known as JavaBeansTM, can plug into existing

component architectures. Object serialization: Allows lightweight persistence and communication

via Remote Method Invocation (RMI).

Java Database Connectivity (JDBC): Provides uniform access to a widerange of relational databases.

J2MEJava 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 applicableto constrained devices, such as AWT and other features.

J2ME defines configurations and profiles.

2 Configuration CLDCConnected Limited Device Configuration,

Device with 160

512 KiloByte memory, Part of J2SE feature, prosesor16 or 32 bit

CDCConnected Device Configuration Minimum memory 2 Mbyte, Full J2SE features, Prosesor 32 bit

Profile : MIDP, FP, Personal, RMI Profile, PDA Profile.

JAVA Card

Java Card technology provides a secure environmentfor applications that run on smart cards and otherdevices with very limited memory and processingcapabilities.

Multiple applications on a single card, and new onescan be added to it even after it has been issued to theend user.

Applications written in the Java programming

language can be executed securely on cards fromdifferent vendors

Many used with Java Security

JINI Network Technology

Jini network technology, which includes JavaSpacestechnology and Jini extensible remote invocation (JiniERI), is an open architecture that enables you tocreate network-centric services--whetherimplemented in hardware or software--that are highlyadaptive to change. You can use Jini technology tobuild adaptive networks that are scalable, evolvable,and flexible, as typically required in dynamic

computing environments

Network Controller

Example : Monitoring temperatur via web

a set of Java technology APIs that enable the

rapid development of Java based next

generation communications products and

services for the Java platform

JXTA

You can use JXTA technology to create peer-to-peer(P2P) applications based on Java technology.

JXTA technology is a set of open protocols thatenable any connected device on the network, ranging

from cell phones and wireless PDAs to PCs andservers, to communicate and collaborate in a P2Pmanner.

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 arebehind firewalls and network address translations(NATs) or on different network transports.

OSS & Java

The OSS through Java Initiative ("OSS" stands for"Operations Support Systems") produces a standard set of Javatechnology-based APIs to jump-start the implementation ofend-to-end services on next-generation wireless networks, and

leverage the convergence of telecommunications and Internet-based solutions.

OSS/J (www.ossj.org) focusing on the business needs ofService Providers and the broader OSS/J community: ISVs,NEPs, and system implementation providers, as well as

telecommunications analysts, consultants and associations.This site (java.sun.com/products/oss) will remain focused onmeeting the needs of Java developers serving thetelecommunications industry.

Java DMK

Java Dynamic Management Kit (Java DMK) is a Javatechnology based toolkit that allows developers to rapidlycreate smart agents based on the Java Management Extensions(JMX) specification. T

he power of the JMX framework is that it supports multipleprotocol access to management information residing in theagent.

The latest release of Java DMK, conforms to JMX v.1.2 andJMX Remote API 1.0. The JMX specification defines a three-level management architecture:

The instrumentation level makes resources manageable as Javaobjects

The agent level exposes these objects for management

The distributed services level allow remote access and security


17/17

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 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
