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.
