What is EJB architecture(components)?

Enterprise beans
An enterprise bean is a non-visual component of a distributed, transaction-oriented enterprise application. Enterprise beans are typically deployed in EJB containers and run on EJB servers.

There are three types of enterprise beans: session beans, entity beans, and message-driven beans.
Session beans: Session beans are non-persistent enterprise beans. They can be stateful or stateless. A stateful session bean acts on behalf of a single client and maintains client-specific session information (called conversational state) across multiple method calls and transactions. It exists for the duration of a single client/server session. A stateless session bean, by comparison, does not maintain any conversational state. Stateless session beans are pooled by their container to handle multiple requests from multiple clients.

Green Skyscraper

Expected to be the first LEED Platinum skyscraper,

the 945-foot- (288-meter-) tall Bank of America Tower is located at 42nd Street and 6th Avenue in Manhattan, opposite Bryant Park.

The 2.2 million-square-foot (204,000-square-meter) high-rise tower was developed as a joint venture between the Durst Organization and the Bank of America, and was designed by Cook + Fox Architects, with executive architect Adamson Associates Architects. Bank of America will occupy three-quarters of the building as its New York headquarters.

The base of the tower creates a variety of important public spaces, including the restored Henry Miller Theater on 43rd Street. It also provides three times the public circulation space of a typical as-of-right office building, including an urban garden room and a new entrance to the Times Square subway station.

The integrated strategies for this high-rise building focus on daylighting and indoor air quality, which foster human comfort and employee productivity. The double-glazed envelope consists of floor-to-ceiling low-iron, low-E glazing for maximum transparency and thermal performance.
