1 Software Development & Education Center Java Advance Frameworks (Struts Hibernate Spring)

2 STRUTS 2.0 Apache Struts is an open-source framework for creating Java web applications that use the MVC design pattern. The Struts framework is particularly useful for larger web applications. Although the Struts framework was popular early in the history of the Java language it has gradually been replaced in popularity with other Java web frameworks, particularly Java Server Faces, or JSF. For those looking to write Java web applications that will be deployed to more recent Java EE application servers training in JSF may be greatly beneficial. This course introduces the students to Struts. During the course, students will learn to design and develop Struts based applications. Students learn how to incorporate JSPs, servlets, EJBs and JavaBeans into their design. Corresponding to every chapter, there is a lab reinforcing the concept. Objectives Understand and explain the Struts framework Design and build Struts based applications Audience This course is intended for programmers and designers who want to design and develop applications using the Struts Model-View-Controller (MVC) framework. Prerequisites A good understanding of HTML. A good understanding of object-oriented programming using Java. Experience with JSPs and servlets with some understanding of JavaBeans or EJBs.

3 Detailed Curriculum Struts Architecture and Overview Introduction to Struts Objectives Review: MVC model What is Struts? Struts flow Components in Struts? The Model The View The Controller struts-config.xml The <data-sources> element The <form-beans> element The <global-forwards> element The <action-mappings> element Sample The role of web.xml for the application Configuring Struts in web.xml web.xml content Steps to configuring Struts in web.xml Sample Summary A Simple Struts Application The Goal of the Application The input form The struts-config.xml

4 The Form Bean class The Action class The result page Struts features in Eclipse Objectives Struts binary distribution Directory structure of Struts application Example Eclipse support for Struts Developing a web application using Eclipse features of Struts Struts Development Cycle Objectives Struts development cycle Gathering requirements Defining screen requirements Data vs. FormBean define FormBean Determining the screen flow Defining the ActionMappings in struts-config.xml Developing the FormBean The reset ( ) method Form validation using the validate ( ) method ActionError Define message key Developing Action Class Action and Action Class The execute() method

9 Hibernate 3.0/4.0 You Will Learn How To: Implement object persistence with Hibernate Map objects to databases using XML and annotations Optimize data access with Hibernate Query Language (HQL) Course Benefits Moving data back and forth from a database system and the object model of a Java application is harder than it seems to be. In this course, Java developers learn how to quickly build enterprise Java applications using the industry-standard Hibernate framework. Through intensive hands-on exercises, you learn how to bridge the gap between object-oriented domain models and relational database systems. Who Should Attend Architects, programmers, engineers, managers and those involved in the development of complex enterprise-level Java applications. Knowledge of Java at the level of Java Programming, plus real-world Java programming experience, is assumed.

10 Detailed Curriculum Introduction What is Hibernate? Object Relational Mapping JDBC v/s Hibernate Installing Hibernate Using Hibernate with an IDE Getting Started POJOs and Persistence Creating Hibernate Mappings Configuration Session Factory Session Working with Entities Transactions Queries Tying Everything Together Mapping with Annotations Introduction to Annotations Annotation Pros and Cons Using Annotations in Your Application Mapping Entities and Tables Mapping Columns and Data Types Mapping Associations Mapping Collections

11 Mapping with XML Mapping Entities and Tables Mapping Columns and Data Types Mapping Associations Mapping Collections Working with Persistent Objects Object states in Hibernate Common Hibernate Methods Working with Entities Working with Bidirectional Associations Flushing the Session Cascading Operations Orphans Lazy Associations Querying with HQL The Hibernate Query Language Retrieving Data Using Operators Sorting Results Using Aggregate Functions Grouping Results Using Joins Using Parameters Transactions Hibernate and Thread-Safety Introducing the Hibernate Util Class Committing and Rolling Back Transactions

12 SPRING The Spring Framework is a lightweight solution and a potential one-stop-shop for building your enterprise-ready applications. However, Spring is modular, allowing you to use only those parts that you need, without having to bring in the rest. Spring enables you to build applications from "plain old Java objects" (POJOs) and to apply enterprise services noninvasively to POJOs. This capability applies to the Java SE programming model and to full and partial Java EE. The Spring Framework 3.0 provides an option for configuration through annotations instead of XML and support for some of the latest Java EE 6 features. OBJECTIVES Upon completion of this course, you should be able to: Understand the need for the Spring framework Integrate Spring with the JPA ORM framework Use the Spring MVC web framework to develop flexible web applications Use Spring Web Flow to create conversational web applications Integrate Spring with JSF applications Use AJAX with Spring AUDIENCE Software designers, developers and programmers.

23 Skills Development Workshop Communication is something which all of us do from the very first day of our life, yet there is a question that haunts us most of the time Did I express myself correctly in such and such situation? The answer to this question is really tricky, because in some cases we leave our signatures and good impression but in some others we even fail to get our idea clearly. It happens mostly because we don t know how to act in certain situations. Every time we fail we don t lose completely, we do learn something, but prior knowledge of the same thing could be more beneficial because then we could have turned that failure into success. The course / workshop would focus at many aspects of personality, like: Building positive relationships with peers & seniors Building self-confidence & Developing clear communication skills Exploring and working on factors that help or hinder effective interpersonal communication Learning impacts of non-verbal behavior & Dealing with difficult situations and difficult people Workshops Consists of Following Activities: Personality Development Group Discussions & Debates Seminars & Presentations Case Studies & Analysis Corporate Communication Development HR & Interview Skills Management Games & Simulations Aptitude, Logical & Reasoning Assessments & Development
