Chris, thanks for the anaswer!!

The findMembershipsGroupsMember is a private method... So I cannot call it.

I tried to call findMembership, which is public, but I get the error:

java.lang.RuntimeException: Membership must be immediate!

Hi *,

I'm writing an interface upon the Grouper Java Objects (namely the VOOT connector).

Within this interface I need, at some point, to retrieve the Membership object of a Subject within a specific Group.

For this purpose, I've so far user the following snippet of code:


Membership membership = MembershipFinder.findImmediateMembership(grouperSession, theGroup, theSubject, false);



This works perfectly right, but only retrieves direct membership (as the method name suggest really strongly).

I was wondering how I could retrieve direct and indirect membership.

I suppose I have to use the MembershipFinder.findEffectiveMemberships method... but it has some parameters which makes it not completely clear to me how I could achieve my goal...


Has someone already solved a similar problem (the UI solves this problem, for instance) and is able to share a snippet of code to do obtain the membership of a user to a group (direct or indirect)?


Thank you very much!
