It is said that Java has bought life to the web applications. True. It has the power to deal with all complexities with grace, which is the main reason for its survival in the ever so competent, and progressive, IT World. J2EE: An understanding J2EE web programming is a known form of Java. The J2EE platform is mainly used for the development of enterprise-level applications, which involves mission-critical systems that support the various business processes of the organization. J2EE is not a programming language. It is a specification for writing enterprise applications (distributed computing). Like the best part of Java is code portability, J2EE specification complaint-code is also portable between J2EE-complaint application servers. Challenges in the enterprise Enterprise systems cater to an extremely broad spectrum of applications. It encompasses of systems such as ERPs, Customer Resource Management, Billing Management System, Decision Support systems, Point-of-Sale, Payroll, Stock and Resource Management, etc. Engaging in web development for enterprises brings forth challenges from various directions. In this section, we shall discuss the challenges for building enterprise applications, and how we shall overcome those through J2EE web application development: Security All corporate has security policies in place. This, in itself, communicates the importance of secure applications for enterprises. Enterprises have tight security to protect confidential information from leaking out, due to a million reasons such as unauthorized access, SQL injections, lose code, attacks on web applications, etc. Operational efficiency Corporate consists of thousands of employees and users, globally accessing information. In such a scenario optimized performance and speed over which the app is delivered becomes a challenge. Operational efficiency also covers aspects such as high availability, reliability and scalability, which should be at par while delivering enterprise applications. Enterprise resources Enterprises are often cluttered with resources, which must be carefully negotiated. The system that runs by applying high interoperability with corporate resources, such as data warehouses, integration brokers and content management systems, results in purpose fulfillment. Transaction support The transaction is a fundamental business activity, which presents a real-time challenge. Many of today’s database vendors have offered support to the enterprise level transactions, but true global transactions involve many databases and disparate information systems. J2EE web programming practice helps overcome these challenges. It offers some real-time benefits and simplifies the process of creating robust enterprise systems. In the next section, we’ll see benefits of J2EE web development. J2EE: A Preferred Choice The J2EE platform efficiently develops and deploys distributed and multitier systems for large scale enterprises. J2EE easily eliminates all the challenges occurred during developing an efficient enterprise system through a rich set of services based around object distribution, security, transaction management and so on. J2EE is made to reduce the developer effort significantly. It also reduces the cost overhead by providing a robust architectural infrastructure. There is a lot more that J2EE web application development practice offers. Work with it to experience the difference.
