How to Call RFC from PortalService using a ServiceUser

Question

Hi,
I have some code that calls an RFC using JCO.
(I have other code I wrote using JCA to connect from a portlet, but that requires a Session and uses an IProfile)
Our security team wants me to use a Serviceuser instead. But I can't seem to figure out how to use a ServiceUser to call an RFC.
If I can just get an IConnection, i can use the rest of my JCA code to call the RFC. But I'm stuck getting the connection
The closes I've gotten is this:
com.sapportals.portal.security.usermanagement.IUser user = WPUMFactory.getServiceUserFactory().getServiceUser("myserviceuser");
IConnectorGatewayService cgs=PortalRuntime.getRuntimeResources().getService (IConnectorGatewayService.KEY);
ConnectionProperties cp=new ConnectionProperties(new Locale(),user);
IConnection conn=cgs.getConnection("mySAPsystemalias",cp);
There are two problems with this (or maybe more)
The connectionproperties takes an IProfile not an IUser
I also thought I needed a com.sap.security.api.IUser, not the one above.
Can someone point out what is wrong or a different way?
thanks

Chris,
You could always use a JCO JNDI connection, in which case you dont need anything other than a HashMap of the the following properties
client
messageserverHost
systemLangauge
group
type
systemType
systemId
serverPort
username
password
The username and password you supply can be a service user or a normal logon user as far as I know.
Cheers,
