/**
* FactoryBean that obtains a specified WebLogic {@link javax.management.MBeanServer}
* reference through WebLogic's proprietary Helper /
* MBeanHome API, which is available on WebLogic 6.1 and higher.
*
* 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 {@link WebLogicJndiMBeanServerFactoryBean} for
* accessing the WebLogic MBeanServer instance through a WebLogic
* MBeanHome obtained via a JNDI lookup, typical a local one.
*
*
NOTE: This class is only intended for use with WebLogic up to 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>
