Java.lang.NullPointerException in LabSolution02.java

Question

Hi,
I am getting this java.lang.NullPointerException while running LabSolution02.java.
We have only Content services and Records Manager installed. My folder structure is
Site--> container --> library --> files
Code is failing at this point after authentication..
log("Looping through user's requested attributes ...");
returnedAttributes = user.getRequestedAttributes();
int len = (returnedAttributes == null) ? 0 : returnedAttributes.length;
for (int i = 0; i<len; i++)
NamedValue nv = returnedAttributes;
log("found NamedValue pair "
nv.getName() " type: "
+ nv.getValue().getClass().getName());
basically nv.getName() is returning "PERSONAL_WORKSPACE:ID"
but nv.getValue() is returning null. thats why its giving nullpoint exception.
any reason why its not returning any value?

Hi ,
The "Library" item you see in the Content Services Web UI is actually internally named in our product (from an API perspective) as a Workspace.
Do not confuse this Content Services Workspace Item with the Oracle Workspaces product - it is just pure unfortunate conincidence.
Oracle Workspace has its own set of Web Services.
oracle.workspaces.ws.AdministrationService
oracle.workspaces.ws.AnnouncementsService
oracle.workspaces.ws.AttachmentsService
oracle.workspaces.ws.AuthenticationService
oracle.workspaces.ws.DiscussionService
oracle.workspaces.ws.HomeService
oracle.workspaces.ws.InboxService
oracle.workspaces.ws.LibraryService
oracle.workspaces.ws.MeetingsService
oracle.workspaces.ws.S2SAuthenticationService
oracle.workspaces.ws.TasksService
oracle.workspaces.ws.TemplateService
oracle.workspaces.ws.UsersService
oracle.workspaces.ws.ViewsService
oracle.workspaces.ws.WorkspacesService
Whereas the Content Services / Content DB Web Services are:
oracle.ifs.fdk.ArchiveManager
oracle.ifs.fdk.AuditManager
oracle.ifs.fdk.CategoryManager
oracle.ifs.fdk.CommonManager
oracle.ifs.fdk.ContainerManager
oracle.ifs.fdk.DomainManager
oracle.ifs.fdk.FileManager
oracle.ifs.fdk.GroupManager
oracle.ifs.fdk.LockManager
oracle.ifs.fdk.PagingManager
oracle.ifs.fdk.ProgressManager
oracle.ifs.fdk.QuotaManager
oracle.ifs.fdk.RecordsManager
oracle.ifs.fdk.RemoteLoginManager
oracle.ifs.fdk.RequestManager
oracle.ifs.fdk.SearchManager
oracle.ifs.fdk.SecurityManager
oracle.ifs.fdk.ServiceToServiceLoginManager
oracle.ifs.fdk.SessionManager
oracle.ifs.fdk.SortManager
oracle.ifs.fdk.SystemConfigurationManager
oracle.ifs.fdk.TrashManager
oracle.ifs.fdk.UserManager
oracle.ifs.fdk.VersionManager
oracle.ifs.fdk.VirusManager
oracle.ifs.fdk.WorkflowManager
oracle.ifs.fdk.WorkspaceManager
Oracle Workspaces actually leverages the Content Services WorkspaceManager web service in order to create the Library (aka internally workspace) in Content Services that is used as part of the collaboration.
So to clarify things:
Library (UI) = Workspace (API)
Site (UI) = Domain (API)
And Workspace in Content Services API has nothing to do with Oracle Workspaces.
cheers
Matt.
