Constructor Detail

RequiredModelMBean

public RequiredModelMBean()
                   throws MBeanException,
                          RuntimeOperationsException

RequiredModelMBean

public RequiredModelMBean(ModelMBeanInfo info)
                   throws MBeanException,
                          RuntimeOperationsException

Constructs a RequiredModelMBean object using ModelMBeanInfo passed in. As long as the RequiredModelMBean is not registered with the MBeanServer yet, the RequiredModelMBean's MBeanInfo and Descriptors can be customized using the setModelMBeanInfo(javax.management.modelmbean.ModelMBeanInfo) method. After the RequiredModelMBean's MBeanInfo and Descriptors are customized, the RequiredModelMBean can be registered with the MBeanServer.
