create a task vsphere sdk

Hi all ,

We are working on the vSphere plugin and currently got stuck with creating a tasks in the vSphere webclients recent tasks.

we need to add a task to the recent tasks tab for any operation we do on the plugin we are developing .

My code looks like this :

    UserSession userSession = _userSessionService.getUserSession();
    ServerInfo[] sinfo = userSession.serversInfo;
    String sessionCookie = sinfo[0].sessionCookie;
    String serviceUrl = sinfo[0].serviceUrl;
    ServiceContent serviceContent = getServiceContent(sinfo[0].serviceGuid);
       
    ManagedObjectReference extensionReference = serviceContent.getExtensionManager(); 
    _taskMgrReference = serviceContent.getTaskManager();
   _vimPort.createTask(extensionReference,_taskMgrReference,"Rakesh","Bandari",true,"Administrator","TestFault");

this code doesn't work for me .Can some one please let me know how can i create a cutom task in the vPsphere plugin .

Thanks,

RakeshBandari
