Variants of JAVA

 The Java 2 Enterprise Edition (J2EE) is
 Multi-tiered architecture
 Implementing Enterprise-class applications
 Web based applications.
 Open and standard based platform for
 developing, deploying and managing
 n-tier, Web-enabled, server-centric, and component-
based enterprise applications.
J2EE

 Component based model
 Container provided services
 Highly Scalable
 Simplified Architecture
 Flexible security model
J2EE Features

 Application clients and applets.
 Java Servlet and Java Server Pages technology (Web
Container)
 Enterprise JavaBeans components (enterprise beans)
(EJB Container)
J2EE Components

 Used to develop Server-Side applications.
 Java Servlets
 Java Server Pages
 Java Server Faces
J2EE Uses

 JSP (Java Server Pages) :- Alternate way of creating servlets
 JSP is written as ordinary HTML, with merged Java.
 The Java is enclosed in special tag.
 JSP files must have the extension .jsp
 JSP is translated into a Java servlet, which is then
compiled
 Servlets are run in the usual way
 The browser or other client sees only the resultant HTML,
as usual
JSP

 JSP initialization
 The jspInit() method is executed at the start and only
once.
 If the JSP developer needs to perform
any JSP-specific initialization such as database
connections at the beginning this method can be specified.
 JSP execution
* public_service(HttpServletRequest req,
HttpServletResponse res)
{//code}
 JSP termination
<%! public void jspDestroy(){ . . . } %>
Architecture of JSP

 Struts is a set of cooperating classes, Servlets, and JSP
tags that make up a reusable MVC 2 design.
 Hence, Struts is a framework, rather than a library.
 Contains an extensive tag library and utility classes that
work independently of the framework.
Struts

 Object-relational mapping (ORM) solution for Java
 Data made persistent by storing in a database
 Hibernate takes care of this for us
Hibernate

 JDBC maps Java classes to database tables (and from
Java data types to SQL data types)
 Hibernate automatically generates the SQL queries.
 Hibernate provides data query and retrieval facilities and
can significantly reduce development time otherwise
spent with manual data handling in SQL and JDBC.
 Makes an application portable to all SQL databases.
Hibernate over JDBC
