Constructor Detail

ProxyInvocationHandler

public ProxyInvocationHandler(JmxServiceObj jso)
                       throws java.lang.Exception

Creates new ProxyInvocationHandler If the JmxServiceObj contains a non-null MBeanServer, it will be set as the proxy's MBeanServer. Otherwise it will try to establish a connection to the remote adaptor described by the the JmxServiceObj.

Throws:

java.lang.Exception

ProxyInvocationHandler

public ProxyInvocationHandler(JmxServiceObj jso,
                              MBeanServerInt mbs)
                       throws java.lang.Exception

Creates new ProxyInvocationHandler It set's the proxy MBeanServerInt to the one passed in.

Throws:

java.lang.Exception

Method Detail

setMBeanServerInt

public void setMBeanServerInt(MBeanServerInt mbsi)

Over writes the current MBeanServerInt with the new one. Any connections would either have to be explictly closed first, or left to the garbage collector as this method simply over writes.

getMBeanServerInt

public MBeanServerInt getMBeanServerInt()

setJmxServiceObj

public void setJmxServiceObj(JmxServiceObj jso)
                      throws java.lang.Exception

Sets the JmxServiceObject to this new one. It then over writes the current MBeanServerInt with the new one from the JmxServiceObject. Any connections would either have to be explictly closed first, or left to the garbage collector as this method simply over writes.

Throws:

java.lang.Exception

getJmxServiveObj

public JmxServiceObj getJmxServiveObj()

disconnect

public void disconnect()

If the remote connection to the agent represented by the JmxServiceObj is not null, then close the current one.

connect

public void connect()
             throws java.lang.Exception

Use the JSO to rebuild the MBeanServerInt and get a new connection

Throws:

java.lang.Exception

createNewInstance

public JmxServiceObj createNewInstance(java.lang.String name)
                                throws java.lang.Exception

create a new instance of the MBean described in the JmxServiceObj.getClassName() on the proxied agent.

Throws:

java.lang.Exception

unregisterMBean

public void unregisterMBean()
                     throws java.lang.Exception

unregister the instance of the MBean described in the JmxServiceObj.getObjectName() on the proxied agent.

Throws:

java.lang.Exception

getObjectInstance

                                                  throws java.lang.Exception

If there is an ObjectInstance in the JmxServiceObj, it will return this, else it will try to aquire an ObjectInstance from the MBeanServerInt via the jmxServiceObj.getObjectName(), else it will return a null

Throws:

java.lang.Exception
