Role Updation-FDI api

Question

Hi all,
i am trying to update the existing role through Java FDI api(albpmfdi.jar) .I use FuegoFDIAdmin.admin.addRolesToUser(soeId, roles, fuegoParameter, 95) to addroles to user.I dont find any similar utilities to update the existing role.I want to update the permission alone in the existing role.
DirHumanParticipant.getRolesAssignment() returns a string array which comprises of permission value.But it is a final variable so no new assignment could not be made.
I tried FuegoFDIAdmin.admin.addRolesToUser(soeId, roles[i], fuegoParameter, 255) again to see if that updates the existing role.But that throws exception since role already exists.
can anybody find a way out and can explain me what DirHumanParticipant.addpermission(int) will do .I tried this also but it doesnt have any impact.What is a user permission and permission added to a person with role ,How these both various.I will be grateful if somebody explains the user permission since i know what the later is meant for("XSARFGP")
Thanks,
Madhanagopal Kumar

Rubén,
Thanks for ur timely reply.But i couldnt replicate the same stuff whatever u did in ALBPM with the FDI Java api's or papi.My code look like this.
We tried the insert and other stuffs which u proposed(see the commented lines below),But unfortunately those utilities are not available in any of the jars like fuegofdi.jar,fuego-papi client.jar ect.can u please help in finding the exact jar where all such stuffs are available to update the permission alone in the existing role and its implementation if possible.Once again my overwhelming thanks for the post.
