Problems Getting Security Information

Question

SDK:  BI 4.0 SP6 - I have both the server and the client tools apps installed on my laptop.
I'm working on an application that pulls folder security information (among many other things!) and exports it to a .csv file so that we can analyze it.  However, it appears that the security info is not being pulled correctly.  Here are the various bits of code that I'm using:
CMS Query:
Select * from CI_INFOOBJECTS where SI_KIND = 'Folder' order by SI_NAME
For each folder returned in the above query, information is stored in a FolderInfo object (a class that I've written):
public FolderInfo (IInfoObject fldr, boolean doAdvanced, boolean favFldr) throws SDKException{
  id = fldr.getID();
  title = fldr.getTitle();
  kind = fldr.getKind();
  cuid = fldr.getCUID();
  folder = qh.getParentPath(fldr, "CI_APPOBJECTS");
  favorite = favFldr;
  loadSecurity(fldr, doAdvanced);
The loadSecurity() method is this (SecurityInfo is another class that I've created):
protected void loadSecurity(IInfoObject o, boolean doAdvanced) throws SDKException{
  ISecurityInfo2 si2 = o.getSecurityInfo2();
  IExplicitPrincipals ieps = si2.getExplicitPrincipals();
  for (int i = 1; i <= ieps.size(); i++){
    IExplicitPrincipal iep = ieps.get(i);
    SecurityInfo si = new SecurityInfo(iep, accessLevels, doAdvanced);
    hasAdvancedSec = hasAdvancedSec || si.hasAdvancedRights();
    security.add(si);
The problem that I'm running into is that getExplicitPrincipals() is frequently returning only one principal and that is null instead of containing the correct object principal information the security that has been assigned.
What am I doing wrong?  Thanks!

Hi,
I just took another look at this,
IEffectiveRoles eRoles = iep.getRoles();
for (int i = 1; i <= eRoles.size(); i++){
    IEffectiveRoleeRole = eRoles.get(i);
        if (eRole != null){
               roles.add(eRole.getTitle());
eRoles.get(i) - returns the access level with the given id not the access level at position i. So you'll need to use an iterator to loop through the results and extract the roles:
Iterator<IEffectiveRole> iRoles = eRoles.iterator();
while (iRoles.hasNext()) {
     IEffectiveRole role = iRoles.next();
The same applies to the original posting, IExplicitPrincipals.get(i) gets the principal with the specified id, not the principal at position i.
I should've picked up on this sooner but like you I assumed that .get(i) on the collection would return the object in the collection at position i.
I haven't tested the above - just going by the javadoc. If correct then we should probably raise a ticket in ideas.sap.com to get the methods renamed to something like getPrincipal(int id) getRole(int id) and leave the standard collection get(int position) method in place to get the object at position x.
Let me know how it pans out.
