4.3.5 and 4.3.6 portal fails deploy-undeploy-deploy sequence


    • Bug
    • Status: Closed
    • Minor
    • Resolution: Fixed
    • 4.3.6
    • 4.3.7, 4.4.0
    • None
    • None
    • Liferay 4.3.5. bundled with JBoss and Tomcat


      The portal fails the deploy-undeploy-redeploy sequence for any simple portlet. To reproduce:
      1. Use any portlet (one that extends GenericPortlet) packaged in a war
      2. Deploy the portlet
      3. Add the portlet to a Liferay page
      4. Query the page with the browser - the portlet should work ok
      5. Undeploy the portlet
      6. Query the page with browser - the protlet should write - Portlet is temporarily unavailable
      7. re-deploy the porltet
      8. Query the page with browser - the portlet sould write - Portlet is temporarily unavailable

      Depending on the environment sometimes the whole page fails and a Java error page is rendered instead.

      The cause is that after undeploy of the portlet the com.liferay.portal.service.impl.PortletLocalServiceImpl class keeps a reference to the original class. This should be patched in the portlet undeploy process.

      My solution for the bug:
      1. com.liferay.portal.deploy.hot.PortletHotDeployListener.invokeUndeploy(HotDeployEvent event) add a line:
      Iterator itr = portlets.iterator();

      while (itr.hasNext())

      { Portlet portlet = (Portlet)itr.next(); ... // Insert this line: PortletLocalServiceUtil.removePortlet(portlet); }

      2. Add the referenced method to the PortletLocalServiceUtil class where we delegate the cal to the implementation:
      public static void removePortlet(Portlet portlet)

      { PortletLocalService portletLocalService = PortletLocalServiceFactory.getService(); portletLocalService.removePortlet(portlet); }

      3. In the implementation class (com.liferay.portal.service.impl.PortletLocalServiceImpl):
      public void removePortlet(Portlet portlet)

      { Object removed=_getPortletsPool().remove(portlet.getPortletId()); clearCaches(); }

      Where clearCaches() is the two lines that are present in the initEAR and initWAR methods:
      private void clearCaches()

      { // Refresh security path to portlet id mapping for all portlets _portletIdsByStrutsPath.clear(); // Refresh company portlets _companyPortletsPool.clear(); }

      These patches have solved the undeploy-deploy problem for me
