Field Detail

s_jvmMBs

protected static final Map<MBeanServer,JvmMBMBean> s_jvmMBs

A map containing the MBean Server as key and the JvmMB as value.

Loader

public Loader()

Method Detail

getServer

public MBeanServer getServer()

Returns the MBean Server of this ApplicationContext.

Returns:

Returns the MBean Server.

setServer

public void setServer(MBeanServer server)

Sets the MBean Server of this ApplicationContext.

Parameters:

server - The MBean Server to set.

setJvmMB

protected void setJvmMB()
                 throws BaseException

Takes the JvmMB Bean from the MBean Server or creates a new JvmMB if no such bean is registered at the MBean Server. The JvmMBs have to be stored in a static map for later Application Contexts referring to the same MBeanServer.

Throws:

BaseException - in case the registration at the MBean Server failed

getObjectNames

public ObjectName[] getObjectNames(MBeanServer server,
                                   String domain,
                                   String keyProperty,
                                   String value)

Returns all object names of the beans in the domain "domain" and where "keyProperty"="name" which are registered on the MBeanServer server.

Parameters:

server - the MBean Server

domain - the domain of the wanted beans

keyProperty - the key property (e.g. name) as registered on the MBean Server

value - the value of the key property

Returns:

an array of object names satisfying the constraints

setApplicationContext

public void setApplicationContext(ApplicationContext applicationContext)

Returns:

The Application Context containing this loader object

isInitAfterPropertiesSet

public final boolean isInitAfterPropertiesSet()

Returns:

Returns the initAfterPropertiesSet.

setInitAfterPropertiesSet

public final void setInitAfterPropertiesSet(boolean initAfterPropertiesSet)

Parameters:

registerJdk15Mbean

protected static void registerJdk15Mbean(MBeanServer ms)

Registers JDK 1.5 MBeans.

Parameters:

ms - The MBeanServer.
