ISchedulerTask and SAP JAVA call

Question

Hi All,
Has anyone made a JAVA call to a SAP RFC from the SchedulerTasks?
The SAP JAVA Connector code requires the IPortalComponentRequest for it to work.  However in the ISchedulerTask run() method, I believe that it can not be obtained.
I am interested to hear from other people with similar experiences or comments.
Cheers,
Vic

I have used ScheduleTasks to grab the data via BAPIs from BW. These requires you to write a portal service that executes the bapi and then the SchedulerTask calls the portal service.
Scheduler Task->Portal Service->RFC or BAPI
You still have one issue which is IPortalComponentRequest. Portal service doesn't have access to it but you can get around it by setting up a SAP system for usermapping and then mapping that userid to a generic userid. Example code:
private IConnection getConnection(
               String alias)
               throws Exception {
IUser user =
UMFactory.getUserFactory().getUserByLogonID("Administrator");     
IConnectorGatewayService cgService = (IConnectorGatewayService) PortalRuntime.getRuntimeResources().getService(IConnectorService.KEY);
ConnectionProperties prop = new ConnectionProperties(user.getLocale(), user);
return cgService.getConnection(alias, prop);
