Currently when the resource of an XMBean is set, there is a reflective check to see if the resource supports a setMBeanInfo(MBeanInfo) method to allow it access to the ModelMBeanInfo instance. We have discussed exposing more injection points in the 5.0 kernel, but I would like to expand the existing 1.2 XMBean descriptor in 4.0 to allow for additional injection points described via a new injection element that specifies the mapping from the injection point type to resource setter method:

<xmbean>
...
 <injection id="MBeanServer" method="setMBeanServer" />
 <injection id="MBeanInfo" method="setMBeanInfo" />
 <injection id="ObjectName" method="setObjectName" />
</xmbean>
