- 1. Enterprise Java Unit-1 Chapter-1 • What is an Enterprise Application? • What is java enterprise edition? • Java EE Technologies • Java EE evolution • Glassfish server By Prof. SandeepVishwakarma
- 2. What is an Enterprise Application • The Java EE platform is designed to help developers create large-scale, multi-tiered, scalable, reliable, and secure network applications. because these applications are designed to solve the problems encountered by large enterprises. • Enterprise applications are not only useful for large corporations, agencies, and governments, however. • The benefits of an enterprise application are helpful, even essential, for individual developers and small organizations in an increasingly networked world.
- 3. Continue… • The features that make enterprise applications powerful, like security and reliability, often make these applications complex. • The Java EE platform reduces the complexity of enterprise application development by providing a development model, API, and runtime environment that allow developers to concentrate on functionality. • Enterprise as work means communities and organizations. Therefore we can say enterprise applications respond to the requirements of organizations, enterprise problems and focuses these.
- 4. Features of Enterprise Applications • Persistent Data - Enterprise applications usually involve persistent data. The data is persistent because it needs to be around between multiple runs of the program— indeed, it usually needs to persist for several years. Also during this time there will be many changes in the programs that use it. • Lots of Data - There's usually a lot of data, a moderate system will have over 1 GB of data organized in tens of millions of records—so much that managing it is a major part of the system • Access Data Concurrently - Usually many people access data concurrently. For many systems this may be less than a hundred people, but for Web-based systems that talk over the Internet this goes up by orders of magnitude
- 5. Continue… • Lot of User Interface Screens - With so much data, there's usually a lot of user interface screens to handle it. It's not unusual to have hundreds of distinct screens. • Integrate with other Enterprise Applications - Enterprise applications rarely live on an island. Usually they need to integrate with other enterprise applications scattered around the enterprise. The various systems are built at different times with different technologies, and even the collaboration mechanisms will be different.
- 6. Java Enterprise Edition The Java EE stands for Java Enterprise Edition, which was earlier known as J2EE and is currently known as Jakarta EE. It is a set of specifications wrapping around Java SE (Standard Edition). The Java EE provides a platform for developers with enterprise features such as distributed computing and web services. Java EE applications are usually run on reference run times such as microservers or application servers. Examples of some contexts where Java EE is used are e- commerce, accounting, banking information systems.

- 11. Java EE Evolution Java EE was formerly called Java 2 Platform, Enterprise Edition (J2EE) until name was changed to Java EE in version 5. o Java EE categorized in to following version Java EE5 Java EE6 Java EE7
- 12. Java EE5 • It is introduced in May 11, 2006 by Oracle. • The aim of the Java EE 5 platform is to provide developers a powerful set of APIs while reducing development time, reducing application complexity, and improving application performance.
- 13. Java EE 5 SDK Features • First robust, commercial, compatible Java EE 5 implementation. • EJB 3.0 support for POJOs means less to learn, less to code, and less to maintain. • JavaServer Faces 1.2 facilitates building Web 2.0 applications with Ajax. • Higher throughput, faster response time, and improved management features to streamline deployment. • Web services performance increased up to 5 times. • Provides a visual SOA development and deployment environment with integrated
- 14. Java EE6 It is introduced in December 10, 2009. The most important goal of the Java EE 6 platform is to simplify development by providing a common foundation for the various kinds of components in the Java EE platform. Developers benefit from productivity improvements with more annotations and less XML configuration, more Plain Old Java Objects (POJOs), and simplified packaging
- 15. Features of Java EE6 • Java EE 6 platform introduces a lightweight Web Profile targeted at next-generation web applications, as well as a Full Profile that contains all Java EE technologies and provides the full power of the Java EE 6 platform for enterprise applications. • New technologies, including the following: o Java API for RESTful Web Services (JAX-RS) o Managed Beans o Contexts and Dependency Injection for the Java EE Platform (JSR 299), informally known as CDI o Dependency Injection for Java (JSR 330) o Bean Validation (JSR 303) o Java Authentication Service Provider Interface for Containers (JASPIC)
- 16. Java EE7 This technology is introduced in May 28, 2013. The most important goal of the Java EE 7 platform is to simplify development by providing a common foundation for the various kinds of components in the Java EE platform. Developers benefit from productivity improvements with more annotations and less XML configuration, more Plain Old Java Objects (POJOs), and simplified packaging.
- 17. Features of Java EE7 • Batch Applications for the Java Platform • Concurrency Utilities for Java EE • Java API for JSON Processing (JSON-P) • Java API for WebSocket • Implement the enhancements in JSF and JSP in your code. • Implement the enhancements in CDI and Bean Validation in your code. • Implement the enhancements in EJB and JPA in your code. • Update existing applications to EE 7
- 18. Glassfish Server GlassFish is a Java application server project created by Sun Microsystems that allows many developers to generate enterprise technologies that are convenient and scalable, as well as additional services that can be installed based on preference. GlassFish Server Open Source Edition is an open source application server built within the GlassFish community. It is a free, dual-licensed software under the GNU General Public License (GPL) and the Common Development and Distribution License (CDDL). GlassFish was acquired by Oracle in 2010.
- 19. Glassfish Server…Continue GlassFish was developed based on a source code that was released by Sun and Oracle’s TopLink persistence system. The project was launched in 2005 and the first version that supported Java EE 5 was released in 2006. Oracle GlassFish Server provides a server for the development and deployment of Java Platform, Enterprise Edition (Java EE platform) applications and web technologies based on Java technology.
- 20. Features of Glassfish Server GlassFish Server 4.1 provides a server for the development and preparation of Java Platform Enterprise Edition (Java EE) and dynamic and scalable HTML5 applications. Key features include applied science Java seven compatibility, modularity, and rapid repetitive development. Java API for processing JSON (JSON-P) Java EE Competency Utilities Java Message Service (JMS) 2.0
