What is the full form of J2EE?

Answer 1

"Java" refers to both a language and a platform. The runtime and libraries that comprise the platform are based on the Java language and come in 3 flavors: Java SE (Standard Edition): Formerly J2SE but renamed to Java Standard Edition when the Java 2 convention was dropped with the release of Java 5 (formerly J2SE 1.5). It contains a good all-around mix of general purpose libraries including JDBC (Java Database Connectivity), JNDI (Java Naming Directory Interface), RMI (Remove Method Invocation), AWT, and Swing. Java EE (Enterprise Edition): Formerly J2EE (see above). It includes Java Standard Edition plus most of the other Java technologies including JavaMail, Activation, JAXB (Java API for XML Binding), Servlets, JSF (Java Server Faces), JMS (Java Messaging Service), EJB (Enterprise Java Beans), and others. Most of the APIs are very component-oriented and are intended to provide pluggable interfaces for business components to form robust, distributed internet applications. Java ME (Micro Edition): Formerly J2ME. It includes most of Java SE and some additional APIs for handheld devices. Java Enterprise Edition is based on Java, but includes a larger set of libraries than Java Standard Edition, which to most people is synonymous with the word "Java." Note that many of the technologies featured in Java Enterprise Edition are available separately and can be added to the Java Standard Edition platform as needed. Hi! Java is a language and j2ee is a plateform which implements java language. Java can be divided into 3 categories
1.core java
2.advanced java
3.J2EE
core java and advanced java are the standard editions of java where as J2EE is the enterprise edition
witout completing core and advanced java u will not be able to understand J2EE

Answer 2

J2EE: Java 2 Platform Enterprise Edition is basically used for web-based applications or network-based applications.

J2ME: Java 2 Platform Micro Edition version is used for small mobile devices, is a subset of J2SE.

J2EE stands for Java 2 enterprise edition for applications which run on servers, for example web sites.

J2ME stands for Java 2 micro edition for applications which run on resource constrained devices (small scale devices) like cell phones, for example games.

Answer 3

Core Java refers to the core or basic features of java like object orientation, inheritance, classes, objects, threads, etc. It is used to create simple java applications.

J2EE stands for Java 2 Enterprise Edition. It uses features like Servlets, JSPs, Struts, Hibernate etc which are all advanced J2EE concepts that are built on top of java. It is used to create enterprise class applications

Answer 4

J2EE components are JAR-style archives with a strict internal structure. All compiled Java classes of a J2EE application is packaged in J2EE components, which execute within containers inside a J2EE application server. In general, J2EE components consist of sets of compiled Java classes, any required resources (images, libraries etc.), and required XML configuration documents (known as deployment descriptors). As JAR-style archives contain a mandatory top-level directory (META-INF) holding a manifest file (MANIFEST.MF), J2EE components use that directory structure to contain the deployment descriptors. For web applications, the configuration directory is called WEB-INF instead of META-INF.

There are four types of J2EE component:

1. Enterprise Applications. These components provide a top-level structure which contains any number of other J2EE components (except other J2EE Enterprise Applications). The JAR file holding an enterprise application has the suffix .ear, so Enterprise Applications are frequently referred to as EARs.
2. Web Applications. These J2EE components may contain Servlets, Java ServerPages, Tag Library Definitions and plain Java classes or resources as required for proper operation. The documents and Java classes of Web Applications frequently create markup language (HTML, WML, XML, etc.) responses to requests from Web Browsers or business applications. The JAR file holding a Web application has the suffix .war, so WebApps are frequently referred to as WARs.
3. Enterprise JavaBean Applications. These components hold server-side business logic packaged within Enterprise JavaBeans.
4. Resource Applications. These J2EE components hold Java classes that act as drivers or communication gateways to Enterprise Information Systems (EISs). It is highly likely that the manufacturer of an EIS packages its driver into a J2EE resource archive (RAR).

Answer 5

J2EE stands for Java 2 Enterprise Edition. It is used to create enterprise class web applications that can be used by large enterprises and corporations. Most websites of major companies are created using j2ee. Some of the technologies used in J2ee are:

a. Struts

b. Hibernate

c. JSP

d. Servlets

e. Spring

f. etc

there is no difference between java2 and java. its same.

Answer 7

That is short for Java 2, Enterprise Edition. It includes many classes required for large-scale work in larger companies.

Answer 8

Java 2 Platform, Enterprise Edition.
