ok, here is the code:

public interface Bean2 {

    public List<TaskInstance> searchTasks(TaskSearchEvent event, String column, boolean ascending, int firstRow, int pageSize);
    

public class BeanFactory{
    
    public static Bean2 getBean(TaskSearchEvent searchEvent) {        

        if( searchEvent.getTaskAssignment() == TaskAssignment.ASSIGNED_TO_ACTOR ) {
            // assigned tasks
            return (Bean2)JNDIUtil.lookup(Bean2Impl.JNDI_NAME_LOCAL);
        } else ..
    }
    
}

@Stateless
public class Bean2Impl extends AbstractBean implements Bean2ImplLocal{

    public static final String JNDI_NAME_LOCAL = "blabla";
    
    @Override
    protected GenericEntityQuery createInitialEntityQuery(String selectSegment, AssignmentValues actors) {
...
           }
    
}

public abstract class AbstractBean implements Bean2 {
                
    protected abstract GenericEntityQuery createInitialEntityQuery(String selectSegment, AssignmentValues actors);
        
    public List<TaskInstance> searchTasks(TaskSearchEvent event, String column, boolean ascending, int firstRow, int pageSize) {
        if( event != null ) {
            
            GenericEntityQuery q = createInitialEntityQuery("select distinct ti from", actors);
          
            Query query = hibernateSession().createQuery(q.getQueryString());        
            setParametersToQuery(query, q);
            query.setFirstResult(firstRow);
            query.setMaxResults(pageSize);  
            
            return query.list();
        } else {
            return Collections.emptyList();
        }
    }
