IdentityService jbpm: Cannot create group, error while validating

This is what I get when debugging at my IdentityService variable ident:

ident    -> commandService = null
         -> commandService = RetryInterceptor(id=68)

In my jbpm.cfg.xml I have:

<jbpm-configuration>
...
 <import resource="jbpm.identity.cfg.xml" /> 
 ...
</jbpm-configuration>
//I tried using my own IdentityService class, but it didn't work...

Then I have a class where I use IdentityService, called simpleProcessService, with getter and setter.

public class SimpleProcessServiceImpl implements SimpleProcessService{
...
private IdentityService identityService;
...
public IdentityService getIdentityService()
    {

        return identityService;
    }
    public void setIdentityService(IdentityService identityService)
    {

        this.identityService = identityService;
    }

...
}

In my applicationContext-process I have:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
   ...>


    <bean id="transactionManagerJbpm"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">

    <property name="identityService"  value="#{processEngine.IdentityService}"/>
    </bean>
   ...

</beans>

In my test file, I have:

public void testGroups()
    {
         SimpleProcessService simpleProcessService =(SimpleProcessService)ctx.getBean("simpleProcessService");
         TaskService taskService = simpleProcessService.getTaskService();

         IdentityService ident = simpleProcessService.getIdentityService();

         fin开发者_Go百科al int nTasks = 1;
         List<Map<String, Object>> vars= new ArrayList<Map<String, Object>>(nTasks);

         System.out.println("executing process");

         String processKey = "";
         String internalURI = "";
         Map<String,Object> x = new HashMap<String,Object>();
         ProcessInstance processInstance =null;
         List<String> processInstanceIds = new ArrayList<String>();

         //Create nTasks for annotation
         for(int i = 0; i <nTasks ; i++)
         {
                 processKey = Long.toString(System.currentTimeMillis());
                 internalURI = "/videos/test"+i+".flv_" + processKey;

                 x = new HashMap<String,Object>();
                 x.put("internalURI", internalURI);
                 x.put("content", "good");
                 vars.add(i,x);

                 processInstance = simpleProcessService.startProcess("groups", vars.get(i), processKey);
                 processInstanceIds.add(processInstance.getId());

         }


         ident.createGroup("anotacion");

         ident.createUser("silver", "johndoe", "John", "Doe");
         ident.createMembership("silver", "anotacion");

         ident.createUser("david", "joesmoe", "Joe", "Smoe");
         ident.createMembership("david", "anotacion");

         ident.createUser("blanca", "joesmoe", "Joe", "Smoe");
         ident.createMembership("blanca", "anotacion");

....

}

The exception is thrown when I try to create a group, it seems that though ident is not null, it contains null objects...

Any ideas?

In my test class, I access IdentityService like this:

ProcessEngine processEngine = new Configuration().buildProcessEngine();
IdentityService id = processEngine.getIdentityService();

Having this in my applicationContext-process:

<bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine" />

And having implemented a class IdentityServiceImpl that basically calls to IdentityService methods:

public class IdentityServiceImpl extends UserServiceImpl implements IdentityService{


    public IdentityServiceImpl()
{
    //Load users and groups from the DB
}

public void createUser(String userId, String givenName, String familyName) {
    //throw new UnsupportedOperationException("Use method TODO name method");
    createUser(userId,givenName,familyName);
}

public void createUser(String userId, String givenName, String familyName,
        String businessEmail) {
    throw new UnsupportedOperationException("Use method TODO name method");
}

public User findUserById(String userId) {
    try{
        GenericUser gU = loadUser(userId);
        UserImpl user = new UserImpl(gU.getUsername(),gU.getFirstname(), gU.getLastname());
        return user;
    }
     catch (ValidationErrors e) {
        e.printStackTrace();
    } catch (ServiceExecutionException e) {
        e.printStackTrace();
    }

    return null;
}

public List<User> findUsers() {
    try {
        List<GenericUser> gUList = listUsers();
        List<User> userList = new ArrayList<User>();

        for(GenericUser gU : gUList)
        {
            userList.add(new UserImpl(gU.getUsername(),gU.getFirstname(), gU.getLastname()));
        }
        //If there are no users return null, otherwise return the users
        if(userList.size() == 0)
            return null;
        else
            return userList;

    } catch (ServiceExecutionException e) {
        e.printStackTrace();
    }

    return null; 
}

public void deleteUser(String userId) {
    throw new UnsupportedOperationException("Use method TODO name method"); 
}

public String createGroup(String groupName) {
    return createGroup(groupName);
    //TODO UserService 
}

public String createGroup(String groupName, String groupType) {
    return createGroup(groupName, groupType);
}

public String createGroup(String groupName, String groupType,
        String parentGroupId) {
    return createGroup(groupName, groupType, parentGroupId);
}

public Group findGroupById(String groupId) {
    return findGroupById(groupId);
}

public List<Group> findGroupsByUserAndGroupType(String userId,
        String groupType) {
    return findGroupsByUserAndGroupType(userId, groupType);
}

public List<Group> findGroupsByUser(String userId) {
    return findGroupsByUser(userId);
}

public List<String> findGroupIdsByUser(String userId) {
    return findGroupIdsByUser(userId);
}

public void deleteGroup(String groupId) {
    deleteGroup(groupId);   
}

public void createMembership(String userId, String groupId) {
    createMembership(userId, groupId);  
}

public void createMembership(String userId, String groupId, String role) {
    createMembership(userId, groupId, role);
}

public void deleteMembership(String userId, String groupId, String role) {
    deleteMembership(userId, groupId, role);        
}

}

In my cfg.jpdl.xml I just have this:

<?xml version="1.0" encoding="UTF-8"?>
<jbpm-configuration>
  <import resource="jbpm.default.cfg.xml" />
  <import resource="jbpm.tx.spring.cfg.xml" />

    <command-service name="newTxRequiredCommandService">

      <environment-interceptor policy="requiresNew" />
      <standard-transaction-interceptor />

    </process-engine-context>


    <transaction-context>
    <!--<object class="com.playence.platform.services.impl.IdentityServiceImpl" /> -->
    <hibernate-session current="true" />
  </transaction-context>


</jbpm-configuration>

I hope it helps
