For example, following is the structure of an ear that has a web module and an ejb module.
The above Order.ear file contains two modules. One is OrderWEB.war file which is a web module and the other is OrderEJB.jar file which is an ejb module. The META-INF folder of Order.ear file contains the application deployment descriptor (application.xml) and the geronimo application deployment plan (geronimo-application.xml). The web application and the ejb application have packaged only their respective deployment descriptors. But the deployment plans for these modules are provided in the geronimo-application.xml.
The web application (OrderWAR.war) looks up stateless session bean in the OrderEJB.jar module to retrieve the order information. The RetrieveOrderInfoBean in OrderEJB.jar module uses JDBC connection to read the order information from a DB2 database. {
