J2EE

J2EE, Java2 Platform Enterprise Edition from Sun Microsystems, is a technology that is used to minimize complexities of the design and implementation of enterprise applications. Enterprise application frameworks are used in web technologies, security, transaction processing, multithreading, n-tier architectures and component based software development. J2EE is a flexible software, allowing the programmer to deploy J2EE to any application server with minimal changes. J2EE is a reliable and standardized software architecture, guaranteeing longevity of applications and supporting decrease in future costs of development.

J2EE platform supports four-tier application model, including client tier, web tier, business tier and enterprise application model (EIS) tier. J2EE server or application server usually includes business and web tiers. J2EE’s application components from web client or application client exist within the client tier.

J2EE architecture uses containers to separate the complex services of an enterprise application. Transaction and state management, resource pooling and multi-threading are the low level services that J2EE separates from the application logic through their implementation in containers.

IT Professionals can use existing tutorials in the J2EE section to heighten programming skills and development capabilities within Java 2 Platform, Enterprise Edition in Application Development. J2EE articles are excellent tools for any J2EE engineer specializing in J2EE Software Development, Architecture, Web Developer or Consultant.
