After a clean install of NetBeans 8.1, I created a new project choosen in the category Samples/Java EE -> project Scrum Toys (Java EE 6) then run it on the glassfish server first the application is not displayed properly because of some minor bugs : in file : \web\.dashboard.todoTasks.xhtml line 46 : xmlns:c="http://java.sun.com/jstl/core" should be : xmlns:c="http://java.sun.com/jsp/jstl/core" -> no impact because not used file : \web\template.xhtml line 49 and 50 : <h:outputStylesheet library="css/1_1" name="#{skinManager.selectedSkin}"/> <h:outputStylesheet library="css/1_1" name="common.css"/> should be : <h:outputStylesheet library="css" name="#{skinManager.selectedSkin}"/> <h:outputStylesheet library="css" name="common.css"/> -> allows css files to be found line 64 : <scrum:menu image="#{resource['images/menu:barraSuperior-04.png']}" /> should be : <scrum:menu image="#{resource['images/menu/barraSuperior-04.png']}" /> -> allows header image to be displayed The biggest problem is that we cannot add a project. After displaying the form with the "Create New Project" button in the View Projects list we can enter the project name and the dates click the "Create Project" button. Then we return to the list of projects and it remains empty... No exception is found on the server log when creating a project, but one exception is displayed on the console when the application starts : Avertissement: java.lang.NullPointerException at org.eclipse.persistence.platform.server.ServerPlatformUtils.createServerPlatform(ServerPlatformUtils.java:99) at org.eclipse.persistence.sessions.factories.SessionManager.init(SessionManager.java:77) at org.eclipse.persistence.sessions.factories.SessionManager.<clinit>(SessionManager.java:71) at org.eclipse.persistence.internal.jpa.EntityManagerSetupImpl.removeSessionFromGlobalSessionManager(EntityManagerSetupImpl.java:558) at org.eclipse.persistence.internal.jpa.EntityManagerSetupImpl.undeploy(EntityManagerSetupImpl.java:2982) at org.eclipse.persistence.internal.jpa.EntityManagerFactoryDelegate.close(EntityManagerFactoryDelegate.java:268) at org.eclipse.persistence.internal.jpa.EntityManagerFactoryImpl.close(EntityManagerFactoryImpl.java:288) at org.glassfish.persistence.jpa.JPADeployer.closeEMFs(JPADeployer.java:414) at org.glassfish.persistence.jpa.JPADeployer.event(JPADeployer.java:405) at org.glassfish.kernel.event.EventsImpl.send(EventsImpl.java:131) at com.sun.enterprise.v3.server.ApplicationLifecycle.unload(ApplicationLifecycle.java:1067) at com.sun.enterprise.v3.server.ApplicationLifecycle.undeploy(ApplicationLifecycle.java:1099) at org.glassfish.deployment.admin.UndeployCommand.execute(UndeployCommand.java:412) at com.sun.enterprise.v3.admin.CommandRunnerImpl$2$1.run(CommandRunnerImpl.java:539) at com.sun.enterprise.v3.admin.CommandRunnerImpl$2$1.run(CommandRunnerImpl.java:535) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:356) at com.sun.enterprise.v3.admin.CommandRunnerImpl$2.execute(CommandRunnerImpl.java:534) I tried to add a project record directly in the derby database. The record is displayed and then it is possible to add sprints, stories and tasks, but nothing is written in the database. And we still cannot add another project. I have found a way to be able to add a project but it's weird : after launching the application in firefox I go to the glassfish admin console then I remove the password property from the jdbc properties (or rename it, is the same), then I am able to create project. but it's very slow because a lot of exceptions are thrown however the list of projects shows the new project added... when clean and build the project the following alert is displayed in the console (although the persistence file is in the META-INF folder) : Note: Creating static metadata factory ... Note: The persistence xml file [META-INF/persistence.xml] was not found. NO GENERATION will occur!! Please ensure a persistence xml file is available either from the CLASS_OUTPUT directory [META-INF/persistence.xml] or using the eclipselink.persistencexml property to specify its location. Note: Some input files use unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details.
"The biggest problem is that we cannot add a project. After displaying the form with the "Create New Project" button in the View Projects list we can enter the project name and the dates click the "Create Project" button. Then we return to the list of projects and it remains empty.." When a persistence context is created by calling EntityManagerFactory.createEntityManager () method where JTA is enabled , You must run EntityManager.joinTransaction() method to do the synchronization with the database the changes have no effect. Here is the Fixed AbstractManager class: (...) public abstract class AbstractManager { @PersistenceUnit private EntityManagerFactory emf; @Resource private UserTransaction userTransaction; protected final <T> T doInTransaction(PersistenceAction<T> action) throws ManagerException { EntityManager em = emf.createEntityManager(); try { userTransaction.begin(); em.joinTransaction(); T result = action.execute(em); userTransaction.commit(); return result; } catch (Exception e) { try { userTransaction.rollback(); } catch (Exception ex) { Logger.getLogger(AbstractManager.class.getName()).log(Level.SEVERE, null, ex); } throw new ManagerException(e); } finally { em.close(); } } protected final void doInTransaction(PersistenceActionWithoutResult action) throws ManagerException { EntityManager em = emf.createEntityManager(); try { userTransaction.begin(); em.joinTransaction(); action.execute(em); userTransaction.commit(); } catch (Exception e) { try { userTransaction.rollback(); } catch (Exception ex) { Logger.getLogger(AbstractManager.class.getName()).log(Level.SEVERE, null, ex); } throw new ManagerException(e); } finally { em.close(); } } protected static interface PersistenceAction<T> { T execute(EntityManager em); } (...) } the exception is displayed on the console is not a fatal exception. But it can be solved by modifying the "eclipselink.target-database" property in the "persistence.xml" file so that it correctly references the database used. Ex: <property name = "eclipselink.target-database" value = "Derby" />
