EJB applications are packaged as JAR files referred to as EJB JAR files. An EJB application is synonymous with the standalone EJB module (which is not packaged in an EAR). Geronimo provides the ability to deploy standalone EJB modules. The deployment descriptor ejb-jar.xml
is packaged in the META-INF
directory in the JAR file. As we will see later in this section, ejb-jar.xml
may not be required, and the meta information in this case is derived from the annotations. Geronimo integrates OpenEJB to provide EJB3 support. Geronimo/OpenEJB fully supports Container Managed Persistence (CMP), although JPA is considered to be a better approach in Java EE. In this section, we focus on session- and message-driven EJBs.
