Current User info lookup

[fhomasp]

Hey,

I need to lookup the firstname and lastname of the current user, using SDK.  The user logs on normally, has some out-of-the-box functionality but he/she can also go to a custom JSF - Bean page to adjust info.  However, I need to automatically lookup his first and last name so the Alfresco repo (using web service api) can lookup the specific info and populate the bean.  The user should only be able to view/adjust his/her own info.


This might be solved rather easy.  However I have written some kind of class that resolves in an ExceptionInInitializer exception when I redraw the page. I don't really know why and I'd like to know, as I want to learn a bit about Spring in the process.  So if anyone can enlighten me, by all means don't hold back 😉

Getting the current username from the current user proved to be no problem.  Getting that persons properties like Firstname and lastname is.
I can get an ID just fine, a QName as well, but personproperties…  I really can't find it.  And I need it.

And so I have found it, after a long period of searching.  I wasted half a day figuring out what I was doing wrong.  It seems that for fetching User Info from the current user I required a started Transaction.
Why this is required for such a simple operation is beyond me.  That's why I suspect there is a simpler way to do this, and if so, by all means let me know.

Anyway, here is the code, which works.

public void setUp(){
   
      FacesContext context = FacesContext.getCurrentInstance(); 
      ServiceRegistry serviceRegistry = Repository.getServiceRegistry(context); 
      AuthenticationService authenticationService = serviceRegistry.getAuthenticationService(); 
        String username=authenticationService.getCurrentUserName();
        this.username=username;
        System.out.println(username+" \t—> from AuthCheck!!!!!!!!!");

        UserTransaction tx = null;
        try
        {
           //Start the transaction.  Why this is required for such a simple operation is beyond me.
           TransactionService txs = (TransactionService) FacesContextUtils.getRequiredWebApplicationContext(context).getBean("transactionComponent");
           tx = txs.getUserTransaction();
           tx.begin();
            
              PersonService personService = (PersonService)FacesContextUtils.getRequiredWebApplicationContext(context).getBean("personService");
              NodeService nodeService = (NodeService)FacesContextUtils.getRequiredWebApplicationContext(context).getBean("nodeService");
              PersonService ps = serviceRegistry.getPersonService();
                                                 
             System.out.println("\t"+ ps.getUserIdentifier(username));
             NodeRef nr = personService.getPerson(username);
          
        
             String firstName = (String)nodeService.getProperty(nr, ContentModel.PROP_FIRSTNAME);
             String lastName = (String)nodeService.getProperty(nr, ContentModel.PROP_LASTNAME);
       
             System.out.println(firstName +" " +lastName+ " From the Repo!!!!!!!!!!!");
             tx.commit();
             
        }catch (Exception err)
        {
            try { if (tx != null) {tx.rollback();}
            } 
            catch (Exception tex) {tex.printStackTrace();}
            err.printStackTrace();
         }
         finally {
            //Normally I'd end the transaction, but it doesn't seem to feature such a method.
         }
   }
