/**
* FactoryBean that obtains a specified WebLogic {@link javax.management.MBeanServer}
* reference through a WebLogic MBeanHome obtained via a JNDI lookup.
* By default, the server's local MBeanHome will be obtained.
*
* Exposes the MBeanServer for bean references.
* This FactoryBean is a direct alternative to {@link MBeanServerFactoryBean},
* which uses standard JMX 1.2 API to access the platform's MBeanServer.
*
*
Note: There is also a more general {@link WebLogicMBeanServerFactoryBean}
* for accessing any specified WebLogic MBeanServer,
* potentially a remote one.
*
*
NOTE: This class is only intended for use with WebLogic 8.1.
* On WebLogic 9.x, simply obtain the MBeanServer directly from the JNDI location
* "java:comp/env/jmx/runtime", for example through the following configuration:
*
*
* <bean class="org.springframework.jndi.JndiObjectFactoryBean">
* <property name="jndiName" value="java:comp/env/jmx/runtime"/>
* </bean>
