4. INTRODUCTION TO J2EE AND EJBs • J2EE Environment • What is Enterprise Java Bean (EJB) • Basic EJB Environment • Types of EJBs • Why EJBs

5. INTRODUCTION TO J2EE AND EJBs J2EE Environment • J2EE Server Overview • The J2EE platform is essentially a distributed application server environment – a Java environment that provides the following • A runtime infrastructure for hosting applications • A set of Java extension APIs to build applications

6. INTRODUCTION TO J2EE AND EJBs What is Enterprise Java Bean (EJB)? • Enterprise Java Bean (EJB) • Enterprise JavaBeans (EJB) is architecture for server-side component based distributed applications written in Java. • It provides an environment in which components from several manufacturers can be assembled into a working application. • Enterprise beans are specialized components that can encapsulate session information, workflow, and persistent data. • The EJB specification provides a solution for a clear separation of the business logic and the details

7. INTRODUCTION TO J2EE AND EJBs Basic EJB Environment • The EJB components run inside the container of an EJB server. • The container has the connection to the database or to other components • An EJB client can access the EJBs from the same Java Virtual Machine (JVM) or from another JVM over remote interfaces • The EJB home component is comparable to a factory for the EJB objects. • The EJB objects retrieved from the home components can be also local or remote objects

8. INTRODUCTION TO J2EE AND EJBs Basic EJB Environment • An enterprise bean has three parts: • The home interface is used by the client to create and discard beans. • The remote interface is used by the client to execute the bean’s business methods. • The implementation or bean class is where the bean’s business methods and callback methods are implemented. The client never invokes these methods directly; they are invoked by the bean container

10. INTRODUCTION TO J2EE AND EJBs Why EJBs? • ISSUE: • The application developers are confronted with many challenges. Some of the most important ones are managing concurrency, persistence and transactions. As a result, the developers have to either develop proprietary code or buy supporting frameworks. • SOLUTION: • These problems are solved by using enterprise beans. The use of enterprise beans allow developers to focus on the business logic and release them from coding infrastructure and middleware logic, and developers become more productive and efficient. • As with most other technologies, enterprise beans do not provide the unique solution to all problems. Using enterprise beans has advantages and disadvantages. However, the advantages outweigh the disadvantages, especially for more complex applications that require a sophisticated robust and distributed persistent model.

11. WHY APPLICATOIN SERVERS? • Application servers offer server-side support for developing and deploying business logic. • Business logic that may be located on the server or, more often, partitioned across client and server. • Enterprises rely daily on server-side business processing, ranging from mainframe transaction systems to client/server DBMS stored procedures.

12. WHY APPLICATOIN SERVERS? • Running business processes on the server provides the following: • Re-use: • A variety of client applications (HTML-only, Java applets, COM+ components, etc.) can share the same business logic • Intellectual property protection: • Sensitive business logic often includes or manages trade secrets that could potentially be reverse engineered. • Security of business logic: • By leaving the logic on the server, user access can be controlled dynamically, revoked at any time. • Security of network communications: • Application servers allow use of internet-standard secure protocols like SSL or HTTPS in place of less secure proprietary DBMS protocols

13. WHY APPLICATOIN SERVERS? • Manageability: • Server-side applications are easier to monitor, control, and update. • Performance: • Database intensive business logic will often perform much better when located near the database, saving network traffic and access latency. • Download time: • I*Net (intranet + extranet + internet) clients most often require access to many different business processes that could require substantial network bandwidth and client memory to download all logic to the client. • Compute load: • Running compute-intensive applications on servers saves client cycles.

40. COST COMPARISON Sybase EAServer 4.2 • Enterprise Edition: • $20,000 ($28,000 UNIX) Concurrent and per CPU pricing • Advanced Edition: • $7500, ($11,250 UNIX) Concurrent and /CPU pricing. • Small Business Edition: • $2995 /Server pricing only.

41. COST COMPARISON Concurrent User License Vs per CPU / processor license • Per CPU license: • license is based on per processor, if you have dual(2)  processor system then you need to buy two licenses, if you have quad (4) processor powerful machine then you need to buy 4 licenses. • Concurrent User license: • start with 50 concurrent users and then increments. • If you have powerful dual(2) or quad (4) processor machine and #'s of users are not too many then concurrent Users license is preferred. • for example. • For a QUARD (4) processor system Advance Edition license: per CPU for 100 users = 4 x 7,500  == $30,000 Concurrent USER license for 100 users = 2 x 7,500 == $15,000

46. SUMMARY / CONCLUSION Conclusion • It can’t be said that which application server is the best and which server a company should used for J2EE Application Development because all offers full J2EE platform support and selection depends on different other factors like: • What existing technical skills developers have? • How much budget company has to spend on software purchase? • How much hardware resources are available to the developer? • What is the existing development platform? • What is the time frame for project completion? • and many more …
