    How can I get the user information in a GateIn portlet?

    Jozsef Szalai Newbie



      I tried to write a simple portlet, which shows me the information (name, username, e-mail address, etc.) of the currently logged in user. I found this in the GateIn documentation, but I don't know how can I use it (which packages/classes do I need to import, and which .jar files do I have to add to the webproject properties).


      Can anybody show me a whole .java file, which works?


      Thanks a lot,

          Hello Jozsef Szalai,


          If I were you, next time, I would first search this forum or the GateIn doc or both for answers before posting a question – then you wouldn't have to wait. Anyway here is some information:


          import org.exoplatform.container.PortalContainer;

          import org.exoplatform.portal.application.PortalRequestContext;

          import org.exoplatform.services.organization.OrganizationService;

          import org.exoplatform.services.organization.User;


          //  Method to retrieve User details


          User portletUser = null;

          PortalRequestContext portalRequestContext = PortalRequestContext.getCurrentInstance();


          // Get the id of the current user logged in

          String remoteUserName = portalRequestContext.getRemoteUser();

          OrganizationService organizationService = (OrganizationService)PortalContainer.getInstance().getComponentInstanceOfType(



          if (remoteUserName != null) {

          portletUser = organizationService.getUserHandler().findUserByName(remoteUserName);




          You would then find the user details you need in the  portletUser. See  org.exoplatform.services.organization.User.

          There also another way of doing it which the GateIn doc will tell you.

            Hello Benjamin,


            Thanks for your hints it helped a lot, but I still got a null pointer exeption at the PortalRequestContext portalRequestContext = PortalRequestContext.getCurrentInstance(); line. I attached the error log, and the java and jsp files.


            Do you have any idea?

              This is an old post, but it needs correcting. The method:




              appears to not be in the API anymore. I found an alternate way to obtain a PortalRequestContext instance:


              PortalRequestContext context = Util.getPortalRequestContext();


              where Util is in the org.exoplatform.portal.webui.util package.


              This needs to be fixed in the Reference Guide as well. The remainder of the code works fine. FWIW, if you're using Eclipse/JBDS you need to add the following JAR files to your build path:
