Container Model - V
Components and homes are deployed into containers by using configuration and deployment metadata.
Container communicates with the component a set of callback interfaces similar to SessionBean and EntityBean.
Components communicates with the container a set of internal interfaces similar to the EJBContext.
Transient objects are created but they do not need a finder pattern.
Persistent objects support either the factory or finder pattern based on component category.
CORBA components support single (serialize) and multiple threading. Component deployment descriptor specifies the threading model. EJB has a single thread model.
