MBeanFactory (IBM WebSphere Application Server, Release 8.5)

```
public interface MBeanFactory
```
The MBeanFactory creates and registers the MBeans that are the management interfaces for the runtime components in the server. It also unregisters the MBeans upon request. It is a singleton object within each Websphere process.
It receives requests from the runtime environment (activateMBean) to create and register MBeans that represent the WAS server runtime components whenever a new runtime object is deployed.
It also receives requests from the runtime environment (deactivateMBean) to unregister the MBean.
There are also utility methods on the MBeanFactory to access the JMX MBeanServer, obtain a configuration identifier for an Object, and use a configuration identifier to find its associated MBean.

```
    Create and register an MBean.
    A runtime object invokes this method to create and register a ModelMBean that represents it. The runtime object attributes and operations are exposed as a management interface accessible through the WebSphere AdminService API. The MBeanFactory loads the MBean XML Descriptor, creates an instance of the MBean, and register it with the MBeanServer. This version of the activateMBean API requires four parameters.
    
    Parameters:
    type - the type of the MBean.
    collaborator - the RuntimeCollaborator object that has responsibility to bind the ModelMBean with the runtime object(s) such that calls on the management interface are delegated to the appropriate methods of the runtime object(s).
    configId - the String used by the configuration system to identify the configuration data for the managed runtime object.
    descriptor - the file name of the MBean XML descriptor file. If null is specified, the default is MBean type.xml.
    
    Returns:
    the JMX ObjectName for the newly created MBean.
    
    Throws:
    
    AdminException - the parent type for several exceptions that can occur

    Create and register an MBean.
    A runtime object invokes this method to create and register a ModelMBean that represents it. The runtime object attributes and operations are exposed as a management interface accessible through the WebSphere AdminService API.

    Parameters:
    type - the type of the MBean.
    collaborator - the RuntimeCollaborator object that has responsibility to bind the ModelMBean with the runtime object(s) such that calls on the management interface are delegated to the appropriate methods of the runtime object(s).
    configId - the String used by the configuration system to identify the configuration data for the managed runtime object.
    descriptor - the file name of the MBean XML descriptor file. If null is specified, the default is MBean type.xml.
    keyProperties - An optional Properties set that will be added to the JMX ObjectName created for the MBean.
    
    Returns:
    the JMX ObjectName for the newly created MBean.
    
    Throws:
