   Java isa computer programming language  object-oriented  "write once, run anywhere" (WORA)  Developed by James Gosling and team at Sun Microsystems  Released in 1995. JAVA – A brief Introduction

   The Java2 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

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

   Used todevelop Server-Side applications.  Java Servlets  Java Server Pages  Java Server Faces J2EE Uses
• 10.
   JSP (JavaServer 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

  Life Cycle ofJSP
• 12.
   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
• 13.
   Struts isa 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
• 15.
   JDBC mapsJava 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
