I have a class that extends HASingletonSupport. I use the startSingleton() to initiate some services as part of my application. But I am in need of calling some other apis within my HASingletonSupport class on the run from my session bean classes. How do i lookup for my HASingleton...

My bean class just extends HASingletonSupport. I havnt implelement any interface.

My HASingleton class is named InitBean and it has a method myMBeanMethod() with no arguments and no return value, that has to be invoked from my session bean.
I actually tied the following piece of code, but did not succeed...

ObjectName mBeanObject = new ObjectName("InitBean:class=com.test.akhil.init.ejb.InitBean");
Object[] valObj = {};
String[] typeObj = {};
MBeanServer server = MBeanServerLocator.locateJBoss();
server.invoke(mBeanObject, "myMBeanMethod", valObj, typeObj);

even tried

ObjectName mBeanObject = new           ObjectName("jboss.management.local:J2EEServer=Local,j2eeType=ServiceModule,name=system.sar,class=com.test.akhil.init.ejb.InitBean");

but no use..

Any help.
