WPUMFactory.getUserFactory returning NullPointerException

Question

Hi All,
I am trying to do an application for creating a folder in KM repository.
I have written as follows.
public class KMAbstractComp extends AbstractPortalComponent
    public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
          try
     com.sapportals.portal.security.usermanagement.IUser user = WPUMFactory.getUserFactory().getEP5User(request.getUser());
          catch (Exception e)
     response.write(e.toString());
But this statement is returning NullPointerException can anyone help me in this regard to resolve this issue.
Thanks,

Hi Marcel,
Thanks for the reply!!!! 
I have written my code like this.
import com.sap.security.api.*;
import com.sapportals.portal.prt.component.*;
import com.sapportals.wcm.repository.*;
import com.sapportals.wcm.util.uri.RID;
import com.sapportals.wcm.util.usermanagement.WPUMFactory;
public class KMAbstractComp extends AbstractPortalComponent
    public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
          try
               IUserFactory iuf = UMFactory.getUserFactory();
               IUser u =iuf.getUserByUniqueName("user");
               com.sapportals.portal.security.usermanagement.IUser user = WPUMFactory.getUserFactory().getEP5User(u);
               ResourceContext ctxt = new ResourceContext(user);
               RID rid = RID.getRID("/documents");
               IResource resource = ResourceFactory.getInstance().getResource(rid,ctxt);
               ICollection collection = (ICollection)resource;
               IResourceList reslist = collection.getChildren();
          catch (Exception e) {
               response.write(e.toString()
But it is showing NullPointerException.
I tried to juz print the
WPUMFactory.getUserFactory()
. But actuall its is printing null. This might be the problem, i guess. Can u plz tell me the way to resolvve this??
Thanks,
