Chapter 16. CDI Integration

Procedure

1. When running in a JEE environment such as JBoss Application Server, ensure that the mbean satisfies all requirements of the jbpm-kie-services:

   public class EnvironmentProducer {
   
       @PersistenceUnit(unitName = "org.jbpm.domain")
       private EntityManagerFactory emf;
   
       @Inject
       @Selectable
       private UserGroupCallback userGroupCallback;
   
       @Produces
       public EntityManagerFactory getEntityManagerFactory() {
           return this.emf;
       }
   
       @Produces
       @RequestScoped
       public EntityManager getEntityManager() {
           EntityManager em = emf.createEntityManager();
           return em;
       }
   
       public void close(@Disposes EntityManager em) {
           em.close();
       }
   
       @Produces
       public UserGroupCallback produceSelectedUserGroupCalback() {
           return userGroupCallback;
       }
       @Produces
   
       public IdentityProvider produceIdentityProvider {
           return new IdentityProvider() {
                // implement IdentityProvider
           };
       }
   }

2. Configure the deployments/business-central.war/WEB-INF/beans.xml file to change the current settings of the new usergroupcallback implementation:

   <beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://docs.jboss.org/cdi/beans_1_0.xsd">
   
   <alternatives>
     <class>org.jbpm.services.task.identity.JAASUserGroupCallbackImpl</class>
   </alternatives>
   
   </beans>

   Note

   org.jbpm.services.task.identity.JAASUserGroupCallbackImpl is just an example here to demonstrate the settings of the application server regardless of what it actually is (LDAP, DB, etc).
