This section explains the differences in the deployment descriptors of JBoss and JOnAS. As an example, we use a stateless session bean named SB_BrowseRegions and an entity bean called Region.The underlying database in called rubis. SB_BrowseRegions is used to retrieve the list of regions from the database.
In both JBoss and JOnAS, the deployment descriptors must be in the META-INF directory.
