Local fix

Problem summary

• Contentsearch api function raises NullPointerException with
  anonymous user
  Use of the workspace.contentSearch() api method generates NPE
  with anonymous portal user.
  
  
  - - Create Site , SiteArea , Content , AT , PT and as JSP
  component and
  give anonymous access to all of the objects.
  
  - - Use following code in JSP point to above JSP component..
  
  <%@ page import="com.ibm.workplace.wcm.api.*"%>
  <%
  out.println (" <BR> Starting JSP ..<BR>");
  
  Workspace workspace = WCM_API.getRepository
  ().getAnonymousWorkspace();
  out.println (" Workspace .." + workspace);
  
  workspace.setCurrentDocumentLibrary
  (workspace.getDocumentLibrary("Test_Library"));
  
  DocumentId documentId = null;
  
  AuthoringTemplate AT = null;
  SiteArea SA = null;
  Document DOC = null;
  
  DocumentIdIterator AuthIt =
  workspace.findByName(DocumentTypes.AuthoringTemplate,"Test_AT");
  
  if (AuthIt.hasNext()){
  
  documentId = AuthIt.nextId();
  AT = (AuthoringTemplate) workspace.getById(documentId);
  out.println (" <BR> AuthoringTemplate ID .." + AT.getId());
  
  }
  
  DocumentIdIterator SiteAreaIt =
  
  workspace.findByName(DocumentTypes.SiteArea,"Test_SiteArea");
  if (SiteAreaIt.hasNext()){
  
  documentId = SiteAreaIt.nextId();
  SA = (SiteArea) workspace.getById(documentId);
  out.println (" <BR> SiteArea ID .." + SA.getId());
  
  }
  DocumentIdIterator contIt = workspace.contentSearch(AT.getId(),
  new
  DocumentId [] {SA.getId()}, new DocumentId [] {}, new String
  [0], true);
  while(contIt.hasNext())
  
  {
  documentId = contIt.nextId();
  DOC = (Document) workspace.getById(documentId);
  out.println (" <BR> Content title.." + DOC.getName());
  
  
  }
  
  %>
  
  - - Create anonymous page and LRP and configure above JSP
  component annd
  preview them.. It will gove list of the content and
  contentSearch API
  method seems to be working fine..
  
  
  install following IFixes:
  
  
  - - PK69894 and the 97 pre-req iFixes.
  PK67661
  PK67115
  PK70072 and all pre-req iFixes.
  
  - - Try to preview the above Page again , now the JSP does not
  work
  correctly and throws NPE in workspace.contentSearch Method.
  
  
  
  
  The following errors appear in SystemOut.log:
  Exception: java.lang.NullPointerException

  CoreQueries.buildXPathMenuQuery and
  CoreQueries.buildXPathMenuQueryForDraft get user principal info
  this way:
           PrincipalInformation principalInfo =
  PrincipalInformationManager.get(UserManagementUtils.getUser());
  
  but UserManagementUtils.getUser() returns null for anonymous
  user
  

Problem conclusion

• Should instead get user principal info this way:
            PrincipalInformation principalInfo =
  UserManagementUtils.getSessionPrincipalInfo();
  
  which returns correct principal info for anonymous user
