- Elimination of the requirement for EJB component interfaces for session beans. The required business interface for a session bean can be a plain Java interface rather than an EJBObject, EJBLocalObject, or java.rmi.Remote interface.
- Elimination of the requirement for home interfaces for session beans.
- Encapsulation of environmental dependencies and JNDI access through the use of annotations, dependency injection mechanisms, and simple lookup mechanisms.
- Introduction of Java metadata annotations to be used as an alternative to deployment descriptors.
Deployment Plans
The structure of the deployable should look like the following:
| No Format | ||
|---|---|---|
| ||
|- calculator-stateless-ear-2.0-M2.ear
|- META-INF
|- application.xml
|- geronimo-application.xml
|- calculator-stateless-ejb-2.0-M2.jar
|- calculator-stateless-war-2.0-M2.war
|
application.xml: The JAR file is referenced to provide the functionality of this deployable. The WAR file is referenced in order to show the usage of this deployable through a web based interface. The context-root is set to be /calculator-stateless so that the URL for this application will be http://<hostname>:<port>/calculator-stateless.

geronimo-application.xml: Information about the project (e.g. module's unique identification, any dependencies) is described inside the <environment> tag. In this case, there are no dependencies so there is nothing to be listed. However, it is a good idea to give this module some sort of unique identification, so that it can later be referenced by some other deployable application.
