The code now starts the service explicitly , and print the state - verifying that it is running...

		ObjectName objName = new ObjectName(oName);
		if (clientClass != null)  {
		   Object obj = Class.forName(clientClass);
		   SimpleServiceFactory fact = new SimpleServiceFactory(obj);
		   
		   kernel.loadService(objName, 
		   		fact,  obj.getClass().getClassLoader());
	
		   kernel.startService(objName);
		   
		   System.err.println("***Service State is : " 
		   		+ kernel.getServiceState(objName));
		   	
		     KernelBridge kernelBridge = new KernelBridge("geronimo.server");
		     
		     if (kernelBridge == null)
		     	System.err.println("** no kernelBridge!");
		     kernelBridge.invoke(
        	    objName,
			    "main"
		        );
		   }

I used the whipped-up object-name of:

geronimo.client:J2EEApplication=null,J2EEModule=org/apache/geronimo/Client,J2EEServer=client,j2eeType=GBean,name=ClientApplication

... but by the time the invoke() is executed - the service is in STOPPED or illegal state... msg follows..
