 abstract void createLeafMBean(Descriptor descriptor) throws MBeanException
Create jsr77 mBean for the leaf object
The leaf mBean correspond to the child object of rootMBean.
For an ejb stand-alone module it will be ejb
and for a web stand-alone module it will be servlet
and for a connector stand-alone module it will be resource adapter |
abstract void createLeafMBeans() throws MBeanException Create jsr77 mBeans for components within root mBean
The leaf mBeans correspond to the child objects of rootMBean.

and for a web stand-alone module it will be servlets
and for a connector stand-alone module it will be resource adapters |
abstract void createRootMBean() throws MBeanException Create jsr77 root mBean
The root mBean corresponds to either an application
or stand-alone module depending on j2ee type |
abstract void deleteLeafAndRootMBeans() throws MBeanException Delete jsr77 mBeans for the root and its' components |
abstract void deleteLeafMBean(Descriptor descriptor) throws MBeanException Delete jsr77 mBean for the leaf object
The leaf mBean correspond to the child object of rootMBean.
For an ejb stand-alone module it will be ejb
and for a web stand-alone module it will be servlet
and for a connector stand-alone module it will be resource adapter |
abstract void deleteLeafMBeans() throws MBeanException Delete jsr77 mBeans for components within root mBean

The root mBean corresponds to either an application
or stand-alone module depending on j2ee type |
abstract boolean doLoad(boolean jsr77) Loads a deployed application or stand alone module.

failed attempts to load classes from the module).
