A multitiered architecture for implementing enterprise-class applications and web based applications. This technology supports a variety of application types from large scale web applications to small client server applications. The main aim of J2EE technology is to create a simple development model for enterprise applications using component based application model. In this model such components use services provided by the container, which would otherwise typically need to be incorporated in application code.

By constantly extending our expertise in the latest technologies, MetaMontage Services' ( mmts) J2EE framework Focus Group helps customers achieve better return on their technology investments. Our J2EE framework platform for eBusiness delivers a suite of stable, secure, and reliable software product offerings for conducting eBusiness and developing new applications.

With a large team of experienced J2EE consultants and vast J2EE experience, MetaMontage Services is ideally placed to leverage the J2EE framework to deliver next generation eBusiness solutions.

One of the biggest advantages of J2EE architecture is "Write once and run anywhere". MetaMontage Services uses a multi-tier distributed application model for the development of J2EE based applications. Most J2EE web-based enterprise applications are split into four logical tiers, Presentation/Client Tier, Web Tier, Business Logic Tier, and Enterprise Information System Tier.

• The presentation tier focus at presenting the business information to the user and is implemented using Servlets, Applets, JSPs and HTML/WML.
• The web tier might include a JavaBeans class to manage the user input and send it to the enterprise bean classes running in the business tier for processing.
• The business tier is where the core business mechanisms are implemented and is usually encapsulated in EJBs (Enterprise Java Beans).
• The Enterprise Information System tier handles Enterprise Information System Software which includes enterprise infrastructure systems such as Enterprise Resource Planning (ERP), mainframe transaction processing, database systems and is usually accessed through the JDBC API and other standard interfaces provided by the J2EE Connector Architecture.
