[EJB/JBoss] - EntityManager remove does not remove?

by jvojtek

In my application I need to persist data of plan modeled in memory to database. First data of previous instance of plan is deleted and then inserted the new one (I do not want to perform update for some reason). But if I perform checking before persisting new data, method findAll returns also data that has been just deleted by the same instance of EntityManager. I am not able to successfully call method PlannerFacadeEJB.savePlanVersion :-( OS: MS Windows XP JAVA: 1.6 JBoss 4.2.2.GA (the same behaviour on 4.0.5) Situation: | @Entity(name = "DBPlanVersion) | @Table(name = "PLAN_VERSION") | @NamedQueries({ | @NamedQuery(name = DBPlanVersion.findAll, query = "SELECT a FROM DBPlanVersion a"), | @NamedQuery(name = "DBPlanVersion.findByPlanId, query = "SELECT a FROM DBPlanVersion a WHERE a.planId = :planId") | }) | public static DBPlanVersion implements Serializable { | public static final String findAll = "DBPlanVersion.findAll"; | public static final String findByPlanId = "DBPlanVersion.findByPlanId"; | | private int planVersionId; | private int planId; | private String description; | | public DBPlanVersion() { | } | | | @Id | @Column(name = "PLAN_VERSION_ID", nullable = false, length = 10) | @SequenceGenerator(name = "PLAN_VERSION_SEQ", sequenceName = "PLAN_VERSION_SEQ", allocationSize = 1) | @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "PLAN_VERSION_SEQ") | public int getPlanVersionId() { | return planVersionId; | } | | public void setPlanVersionId(int planVersionId) { | this.planVersionId = planVersionId; | } | | @Basic | @Column(name = "PLAN_ID", nullable = false, length = 10) | public int getPlanId() { | return planId; | } | | public void setPlanId(int planId) { | this.planId = planId; | } | | @Basic | @Column(name = "DESCRIPTION", nullable = true, length = 50) | public String getDescription() { | return description; | } | | public void setDescription(String description) { | this.description = description; | } | | public boolean equals(Object o) { | if (this == o) return true; | if (o == null || getClass() != o.getClass()) return false; | | DBPlanVersion that = (DBPlanVersion) o; | | if (planVersionId != that.planVersionId) return false; | | return true; | } | } | | | @Stateless(name = "PlannerFacadeEJB") | @Remote(PlannerFacade3.class) | @Local(PlannerFacade3.class) | public class PlannerFacadeBean implements PlannerFacade3 { | | @PersistenceContext(unitName = "xxx") | EntityManager em; | | public void savePlanVersion(int planId, String description) { | em.setFlushMode(FlushModeType.COMMIT); | planVersionFacade3.deleteByPlanId(planId); | planVersionFacade3.addPlanVersion(planId, description); | } | } | | @Stateless(name = "PlanVersionFacadeEJB") | @Local(PlanVersionFacadeLocal) | public class PlanVersionFacadeBean implements PlanVersionFacadeLocal { | | @PersistenceContext(unitName = "xxx"); | EntityManager em; | | public void deleteByPlanId(int planId) { | // Lets find DBPlanVersion with specified planId | DBPlanVersion dbPlanVersion = findByPlanId(planId); | | if (dbPlanVersion != null) { | log.info("Delete: planId=" + dbPlanVersion.getPlanId() + ", planVersionId=" + dbPlanVersion.getPlanVersionId()); | | // ... delete children records in another entity, code omitted | | // Delete plan versionId itself | em.remove(planVersion3); | } | log.info("DeleteByPlanId: Instance of EntityManager is " + em); | } | | public DBPlanVersion findByPlanId(int planId) { | Query q = em.createNamedQuery(DBPlanVersion.findByPlanId); | q.setParameter("planId", planId); | try { | return (DBPlanVersion) q.getSingleResult(); | } catch (NoResultException e) { | return null; | } | } | | public Collection<DBPlanVersion> findAll() { | return em.createNamedQuery(DBPlanVersion.findAll).getResultList(); | } | | public DBPlanVersion addPlanVersion(int planId, String description) { | DBPlanVersion newDBPlanVersion = new DBPlanVersion(); | newDBPlanVersion.setPlanId(planId); | newDBPlanVersion.setDescription(description); | // Lets check whether plan version with the same plan id already exists | for (DBPlanVersion pv : findAll()) { | if ((pv.getPlanId() == newDBPlanVersion.getPlanId()) && (!pv.equals(newDBPlanVersion))) { | throw new RuntimeException("Unable to insert plan version with the same planId = " + pv.getPlanId()); | } | } | em.persist(newDBPlanVersion); | return newDBPlanVersion; | } | } | Vital questions: . how is possible that EntityManager does not know about removed entity in findAll method? . is there any possibility to use caching? . what is difference between caching queries and EntityBeans? . if em.setFlushMode is set to AUTO, findAll does not return just deleted entity and new data can be persisted. But there are many SQL called (can see in JProfiler) - is this the only way of solution?

[JBoss Portal] - IdentityLoginModule not found

by loucs

hi, I'm a jboss portal noob and i want to write my own custom loginmodule extending UsernamePasswordModule. i read the nm-156 thread, and by extending the AbstractLoginModule class, he still need to use the portal IdentityLoginModule in login-config.xml. i'm thinking that it's caused by some missing actions done by the IdentityLoginModule. My current problem is that i can't find any LoginModule class in portal src. I downloaded the 2.6.4 GA version. additionally, I'm struggling to find the jar containing UsernamePasswordLoginModule i may look stupid but any help would be very nice :) regards, -- Lucas Montes View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4146426#4146426 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4146426

[JBoss jBPM] - Re: is it possible to force the token jump from one node to

by pieter＠TA

Hello syedtaj, I'm affraid your proposed piece of code does not do the job for me. Where with my piece of code, the jump to the new node exactly happens when the exception handler catches the exception, with your piece of code the jump happens after other nodes have been executed, which is not the desired effect.
