* Reviewer: Sridatta
* -AuthRealmMbean's getFielRealm is chaged from creating of the new FileRealm object to gettting it from security pool - Realm.getInstance(name) with casting result to FileRealm.
* This approach will work only for PE because DAS and instance have the same auth-realms.
* -AdminContext expanded by two new methods getAdminMBeanResourcUrl() and getRuntimeMBeanResourcUrl() which used by MBeanRegistryFactory for initialization admin and runtime registries. So, they are become pluggable.
* -AdminContext also notifies MBeanRegistryFactory during its construction. So, AdminContext become "visible" to admin-core/admin classes.
* -Hardcoded output changed to appropriate logger calls.
*
* Revision 1.5 2003/07/29 18:59:35 kravtch
* MBeanRegistryEntry:
* - support for toFormatString();
* - instantiateMBean() method modified to instantiate runtime MBeans as well;
* MBeanRegistryFactory:
* - fixed bug in getRuntimeRegistry();
* MBeanNamingInfo:
* - less strict requirements for parm_list_array size in constructor (can be more then needed);
* BaseRuntimeMBean:
* - exception ClassCastException("Managed resource is not a Jsr77ModelBean") handling;
* ManagedJsr77MdlBean:
* - call managed bean bug fixed ( getDeclaredMethod()->getMethod())
* admin/dtds/runtime-mbeans-descriptors.xml - modified to represent new runtime mbeans;
*
* Revision 1.4 2003/07/18 20:14:44 kravtch
* 1. ALL config mbeans are now covered by descriptors.xml
