    How to use @Startup annotation?

    surajmundada Newbie

      Hi,

      I want to execute a method of bean which brings some static data from a text file and store it in database.

      This should happen only once and at the time of starting the app server.

      I could do it successfully when I mapped the method in pages.xml. But then this method gets executed each time when the page is rendered which is not what I want.

      I read about @Startup annotation and assume that this would serve my purpose.

      I tried to implement that but my method is not getting executed.

      Can some one help me getting a sample example showing the use of @Startup ?

      Regards,

      Suraj

          @Name( "xxx" )
          @Scope( ScopeType.APPLICATION )
          @Startup
          public class MyClass
          {
           @Create
           public void create()
           {
           // init stuff here
           }
          }
          


          The key things are:

          @Startup is only valid with application and session, in your case you want application scope.

          Using @Create to have initialisation code run when the component creates. In this case the component is created on application startup.

          HTH.

          Mike.

            Thanks for the help.

            But it's giving me the problem of illegal state.

            stripDSImpl is DAO in my application.

              post your code. You probably have something else which is SESSION scoped in there. Same thing happened to me when I tried to inject the Messages map into an application scoped component.

                Thanks for the reply.

                Here is the code.

                
                 @Startup
                 @Scope(ScopeType.APPLICATION)
                 @Name("populateCommercialStripsListener")
                 public class PopulateCommercialStripsListener
                 {
                
                 private Logger logger = Logger.getLogger(PopulateCommercialStripsListener.class);
                 private LoggingHelper helper = LoggingHelper.getInstance();
                
                 private StripTypePE stripTypePE;
                
                 @Create
                 public void populateCommercialStrips()
                 {
                 try
                 {
                 // Initialize different modules we reuse from ATB new application.
                 QatbApplicationControl.initQATBComponents();
                
                 // Get the complete list of commercial strips - It returns a map containing the strip names as keys and strip code as values.
                 // We have chosen to put the strip names as keys because the calling program will get the strip description from its name.
                 Map listOfStrips = QATBCommercialStripsManager.getInstance().getListOfStripNames();
                 Iterator iteratorOnStripNames = listOfStrips.keySet().iterator();
                
                 stripTypePE = new StripTypePE(MiscellaneousConstants.COMMERCIAL_STRIP_TYPE,
                 MiscellaneousConstants.COMMERCIAL_STRIP_TYPE_NAME,

                 Long id = MiscellaneousConstants.COMMERCIAL_STRIP_INITIAL_PK;
                
                 StripDS stripDSImpl = (StripDS)Component.getInstance("stripDSImpl",true);
                
                 while (iteratorOnStripNames.hasNext())
                 {
                 String stripName = (String) iteratorOnStripNames.next();
                 String stripCode = (String) listOfStrips.get(stripName);
                 ATBStripDescription strip = QATBCommercialStripsManager.getInstance().getCommercialStrip(stripCode);
                
                 if(stripDSImpl.getStripPE(id) == null)
                 {
                 StripPE objStripPE = createCommercialStrip(strip,id);
                
                 if(objStripPE != null)
                 {
                 populateStripInfo(strip,id,objStripPE);
                 }
                 }
                
                 id++;
                 }
                 }
                 catch ()
                 {
                 ........
                 }
                 }
                
                


                StripTypePE is an EJB3 enitity with Session scope.
                stripDSImpl is DAO with Session scope.

                
                @Stateless
                @Name("stripDSImpl")
                @Scope(SESSION)
                public class StripDSImpl implements StripDS
                {
                 ........
                 ........
                }
                
                
                @Entity
                @Table(name = "STRIP_TYPE", uniqueConstraints =
                { @UniqueConstraint(columnNames ={ "NAME" }) })
                @Name("stripTypePE")
                @Scope(SESSION)
                public class StripTypePE implements Serializable
                {
                 ........
                 ........
                }
                


                is the Session scope of these two classes the root of the problem of "No session context active"?

                  Mike Quilleash Newbie

                  You cannot use a session scoped component from within the @Create method of an application scoped component that has @Startup. If you think about it your create method is getting run as soon as the web application starts up. At this point there will never be an active session scope. The session scope is only available during a client/JSF request.

                  You need to have a look at your components and what purpose they have. Something is definately wrong with your scoping or component interaction.

                  Cheers.

                  Mike.

                    Thanks for all the help.

                    Will try creating new components instead of reusing session scoped components.
