How to get IPrincipal from IUser

Hi,

I wanted to know how to get a reference to an IPrincipal if I have the reference to IUser interface.

Basically I have IResourceContext.

IResourceContext m_context;

I can get IUser from it like

m_context.getUser();

But I have to get IPricipal for JCA (Connector Framework to invoke an ABAP rfc).

I'm unable to figure it out, Kindly help me.

Thanks and regards
