    Injecting PortalObjectContainer into servlet

    Jeroen Koek Newbie

      Version JBOSS 2.4 (latest)

      I want to use the PortalObjectContainer in a servlet.
      I have tried to retrieve it from a context but no luck.

      I want to use it to
      - create portals/pages based on username
      - update portal pages (add/remove/update windows)
      - store user specific settings per portlet.

      I'm already able to use the PortalObjectContainer from out of a portlet, but that means that the complete is updated everytime the user changes
      something.
      Because I'm using AJAX/JSON I want to minimize the updates as possible.



      Can anyone help me?

          you need to inject it in the servlet context using the declarative injection in the file jboss-portlet.xml.

            Julien,

            I tried it.
            I'm getting now a PortalObjectContainer object but I'm not able to retrieve the context. This context makes it possible for me to createPages and Windows.

            Underneath the code that I have used and the jboss-portlet.xml that is part of my servlet deployment.


            Can you give me a new hint?

            Thanks,

            jeroen.

            try
            {
            MBeanServer mbeanServer = MBeanServerLocator.locateJBoss();
            container = (PortalObjectContainer)
            MBeanProxy.get(PortalObjectContainer.class,
            new ObjectName("portal:container=PortalObject"),
            mbeanServer);
            }
            catch (Exception e)
            {
            log.error("Cannot get interceptor stack", e);
            throw new IllegalStateException("Cannot get interceptor stack");
            }
            if (container == null) {
            System.out.println("No portal object container");
            }
            else
            {
            System.out.println( "We got the portal object container" );
            Context ctx = null;
            try {
            ctx = container.getContext();
            }
            catch ( Exception ex ) {
            System.out.println( "Failed to get context" );
            }
            if ( ctx == null ) {
            System.out.println( "PortalObjectContainer context is empty!" );
            }
            }

            <portlet-app>
            <!-- Service injected in the portlet context. -->

            <service-name>PortalObjectContainer</service-name>

              you need to wrap the portal object container usage is a JTA transaction.

                Yes, Thanks.
                It works.
                Now I'm off to the next step and that is making the pages user specific.

                To share the knowledge hereby the code.
                In case someone has improvements please suggest.

                TransactionManager tm = null;
                try {
                InitialContext ic = new InitialContext();
                tm = (TransactionManager) ic.lookup("java:/TransactionManager");
                } catch (NamingException ex) {
                System.out.println("Failed to find transactionmnager" );
                }

                try
                {
                tm.begin();
                try {
                MBeanServer mbeanServer = MBeanServerLocator.locateJBoss();
                container = (PortalObjectContainer)MBeanProxy.get(PortalObjectContainer.class, new ObjectName("portal:container=PortalObject"), mbeanServer);
                Context ctx = container.getContext();

                PortalObject po = ctx.getDefaultPortal();
                out.print("PortalNode " + po.getName());
                System.out.println( "Portal retrieved!" + po.getName() );

                ++loop;
                Portal portal = (Portal) po;
                portal.createPage( "JBOSS rocks!" + loop );
                portal.createPage( "JBOSS rocks again!" + loop );
                portal.createPage( "JBOSS rocks and again!" + loop );
                }
                finally {
                tm.commit();
                }
                }
                catch ( Exception ex ) {
                ex.printStackTrace();
                }

                  Thanks to the injection hint I was able to make my custom NavigationPortlet work which was missing the service injections in the jboss-portlet.xml for the PortalObjectContainer... and:

                  <service-name>PortalAuthorizationManagerFactory</service-name>
                  <service-class>org.jboss.portal.security.spi.auth.PortalAuthorizationManagerFactory</service-class>
                  <service-ref>:service=PortalAuthorizationManagerFactory</service-ref>

                      Hi,

                      In JBOSS portal 2.4 it works. We are trying to use JBOSS portal 2.6 and the Context Class is not in portal-core-lib.jar. Where did it move to? How do I find out.

                      Thanks you very much.
