J2EE is an extremely popular platform when it comes to developing web-based Enterprise Solutions and E-Commerce Portals. Large scale enterprise projects have great demands from system architects and developers for features like flexibility and extensibility in design, maintainability of code for a prolonged period, scalability for increased access and to include new functionality, etc. In recent times, the J2EE platform has emerged as a preferred platform for building such enterprise applications. The J2EE platform provides web services, component model, management, and communications APIs that make it the industry standard for implementing enterprise class service-oriented architecture (SOA) and Web 2.0 applications.

InterraIT has vast expertise in developing portable, robust, scalable and secure server-side Java applications based on the J2EE platform. The company has delivered innovative next generation ebusiness applications in J2EE using SOA framework tailored to the specific needs of the industry segment. The company has expertise in architecture design, business modeling, development and testing, application support as well as legacy migration to J2EE platform.

One of the biggest advantages of J2EE architecture is "Write once and run anywhere". InterraIT 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 aims 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. Web components running in the client tier rely on containers to support such things as client requests, responses and enterprise bean lookups.
• 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.
