This figure shows the hierarchy of the MBeans for JDBC objects. DomainMBean is at the top. Underneath DomainMBean is JDBCSystemResourceMBean and underneath that is a gray box containing JDBCDataSourceBean with JDBCDriverParamsBean, JDBCConnectionPoolParamsBean, JDBCDataSourceParamsBean, and JDBCXAParamsBean underneath it. Text in the box reads "JavaBean representations of JDBC descriptor elements."
