BASIC CONCEPTS

3 Tiers

A 3-tier architecture is an application architecture that splits the user interface

(presentation layer) from the application logic. An "application server" handles

the application logic and interacts with the database. This architecture scales

better and is less complex. Also, new user interfaces can be added easily

without changing the application or database tiers.

application servers, content management systems, and similar tools that

support application development and delivery

A Java virtual machine is software that is implemented on

virtual and non-virtual hardware and on standardoperatingsystems. A JVM provides an environment in which Java

bytecode can be executed

A servlet is a Java program that executes on the server,

accepting client requests and generating dynamic responses

The Java Development Kit (JDK) is an OracleCorporation product aimed at Java developers. Since the

introduction of Java, it has been by far the most widely used

Java Software Development Kit (SDK).

JavaServer Pages (JSPs) are HTML documents that are embedded with special

tags to insert Java code, thereby providing dynamic content. When the user

makes a request on a JSP, the server executes the Java code and generates an

HTML documentJar Java Archive : a java class archive files.

War Web Archive : Web modules which contains Servlet class files,JSP

Files,supporting files, GIF and HTML files are packaged as JAR file with .war( web

achive) extension

Ear Enterprise Archive : All above files(.jar and .war) are packaged as JAR file

with .ear ( enterprise archive) extension and deployed into Application Server or

WeblogicEJBs make it possible for relatively new programmers to develop useful parts of

highly complex, transaction-aware, and scalable enterprise applications, it relays

on Weblogic , etc

The JDBC specification defines an interface for Java programs to use and

an interface for which database vendors can develop custom drivers, two

types of JDBC drivers:

Thick JDBC drivers built on top of the C-based Oracle Net client

Thin (pure Java) JDBC driver to support downloadable applets

JNDI (pronounced jenn-dee) is an API and a standard that Java programs use to

access existing naming or directory services. It is not a naming or directory service.

It is merely the mapping. Different naming and directory services store objects in

different ways.

enterprise applications. By combining Java technology with enterprise

messaging, the JMS API provides a tool for writing enterprise applications thatcommunicate with each other asynchronously.Producer
