    access to other ejb in preDestroy of Singleton causes Component is stopped

    inet_gbo

      Hi,

       

      I'm using jboss 7.0.2.

      When I try to access a stateless ejb in preDestroy method of Singleton ejb the following exception is thrown:

          at sandbox.singleton.MySingleton.ejbRemove(MySingleton.java:25)

       

      The Singleton:

       

      {code}

      package sandbox.singleton;

      import javax.annotation.PostConstruct;

      import javax.annotation.PreDestroy;

      import javax.ejb.EJB;

      import javax.ejb.Singleton;

      import javax.ejb.Startup;

       

      @Singleton

      @Startup

      public class MySingleton {

       

          @EJB

          MySessionBean mySessionBean;

         

          @PostConstruct

          public void ejbCreate() {

              System.out.println("MySingleton ejbCreate");

          }

         

          @PreDestroy

          public void ejbRemove() {

              System.out.println("MySingleton ejbRemove start");

              mySessionBean.doSomething();

              System.out.println("MySingleton ejbRemove end");

          }

      }

      {code}

       

      The other stateless ejb I want to call:

       

      {code}

      package sandbox.singleton;

      import javax.ejb.Stateless;

       

      @Stateless

      public class MySessionBean {

       

          public void doSomething() {

              System.out.println("MySessionBean doSomething()");

          }

      }

      {code}

       

      Is this a bug or normal EJB 3.1 behaviour?

      How can I call an other ejb in preDestroy?

       

      Many thanks

      Günther

          As I normally do, I turned to the EJB spec to find out what is supposed to happen.

           

          Stateless beans are not permitted to access their enterprise beans from @PostConstruct or @PreDestroy.

           

          On the other hand, both Stateful and Singleton beans are.

           

          Therefore, this sounds like a bug in 7.0.2. Are you able to try on 7.1CR1b and see if it does the same thing?

            Hi Stephen,

             

            in 7.1CR1b it's the same problem.

              Hi all,

               

              I have quiet a similar setup on JBoss 7.1.0.Final, but same problem here. I'm accessing a stateless bean from the postConstruct of a singleton bean. The strange part is, I do multiple calls on that stateless. The first call works as expected. On the second call I get the following exception:

               

              {code}

                You are seeing that error in @PostConstruct? What does your code look like?

                  Hi and thanks for the response.

                   

                  Well my code is quiet the same as the opening post

                   

                  {code}

                   

                  @Singleton

                  @Startup

                  public class Singleton {

                   

                  @Inject

                  private PropertiesDAO properties;

                   

                  private String value1;

                  private String value2;

                   

                  @PostConstruct

                  public void setUp() {

                   

                       value1 = properies.read(property1);

                       value2 = properties.read(property2);

                       ...

                   

                  }

                   

                  }

                   

                  {code}

                   

                  and

                   

                  {code}

                  @Stateless

                  public class PropertiesDAO {

                   

                       @persistencecontext

                       EntityManager em;

                   

                       ...

                   

                  }

                   

                  {code}

                   

                  I started JBoss in debug mode and set a breakpoint at the first properties call. The DAO is initialised. The strange part is that the first and even second call sometimes succeeds and the value variables are set. Sometimes the Exception comes up on the first call.

                   

                  This is blocking me extremely right now, but I don't want to exclude the possibility of me doing something wrong ;-)

                          Try a newer version, such as WildFly 8.0.

                           

                          Alternatively you can checkout and build any of the newer 7.x versions as well.
