this is my code:
public class ConsultaAtivoImpl implements ConsultaAtivo {
    private String qfundo=null ;
    private String qativo=null ;
    private String qop=null ;
    private String qdata=null ;
    private Dbconn conn ;
    private EntityManager em ;
    private SimpleDateFormat format=new SimpleDateFormat( "dd/MM/yyyy");
    //Query query ;
    private String strq="select a from Ativos a ";
    private CriteriaBuilder qb ;
    private CriteriaQuery<Ativos> query ;
    private Root<Ativos> ativos;
    
    public ConsultaAtivoImpl(){
        //conn = DbconnImpl.getInstance();
        conn = Installer.getEm();        
        em = conn.getConn();        
        qb = em.getCriteriaBuilder();
        query = qb.createQuery(Ativos.class);
        ativos = query.from(em.getMetamodel().entity(Ativos.class)); // <==== here is the point happen the problem 
        
    }
Comment 2 Marian Mirilovic 2010-11-19 13:01:20 UTC 
This is not a NetBeans code : 

java.lang.NullPointerException
        at
br.com.thinkit.editor.PainelTopComponent.<init>(PainelTopComponent.java:37)
Comment 3 obrienmi 2011-03-03 19:27:07 UTC 
The workaround for DI 101 and bug# 338837 to fix the IAE issue for Criteria/Metamodel users attempting to use an EntityType that is not found is to specify the location of the classes (usually not required for Java EE environments)
This environment will exist in Java SE, Spring and certain implementations of Java EE 6 Web Profile.

Exception in thread "main" java.lang.IllegalArgumentException: The type [null] is not the expected [EntityType] for the key class [class org.eclipse.persistence.example.distributed.collatz.model.UnitOfWork].

20110303: We have reproduced this issue in bug# 338837 in a Java SE environment. We have two workarounds and will be modifying the code to warn about the actual cause - which is a not fully specified data model in persistence.xml. 

The following specification mandated JPA 2.0 IllegalArgumentException occurs because entity classes were not processed because they are missing from the search path or not specified. 
This usually occurs in Java SE environments only. 
This is the result of an incomplete specification of the entities in persistence.xml for Java SE RESOURCE_LOCAL environments and possibly Java EE 6 Web Profile JTA environments. 
Occurs when running JPA 2.0 Criteria or Metamodel code where we require an EntityType like the following 
EntityType unitOfWork_ = getEntityManager().getMetamodel().entity(UnitOfWork.class);
        Root<UnitOfWork> root =  getEntityManager().getCriteriaBuilder().createQuery().from(UnitOfWork.class);DDLGenerationClient [Java Application]

Result is OK with either fix

Solution: 
There are two ways into this problem. 
1) We specify no entities at all and also do not specify 
<exclude-unlisted-classes>false</exclude-unlisted-classes> 
- the result of this is a completely empty metamodel 
2) We specify only part of the entities via <class> properties 
- the result of this is selective IllegalArgumentException errors thrown when we attempt to use the missing EntityType classes - likely in a Criteria API query 
We need to warn both for no (0) entities found and later that a specific type was not found - possibly as a result of a missing class reference 
1) warn the user that no entities were found during the predeploy so the deploy iterates nothing during metamodel.initialize - actually nothing is done during initialize 
MetamodelImpl@21350241 [ 0 Types: , 0 ManagedTypes: , 0 EntityTypes: , 0 MappedSuperclassTypes: , 0 EmbeddableTypes: ] 
or in 
protected void initializeCanonicalMetamodel(Metamodel model)

            EntityManagerFactoryImpl.getMetamodel() line: 531    
            DDLGenerationClient.initialize(String) line: 137    
            DDLGenerationClient.doQuery() line: 453    
            DDLGenerationClient.main(String[]) line: 444    
Descriptors map is empty - we need to warn the user about this 
this    MetamodelImpl  (id=37)    
    session    ServerSession  (id=40)    
        descriptors    HashMap<K,V>  (id=61)    
            size    0    
2) Change the IAE for a single missing entity to suggest that the entity class may not have been found or specified (it may be on purpose) 
Security note: A search for a non-existent entity class may come through a user-generated query and may be a way of testing the system for hidden classes 
- we may want to not print the name 
The error message needs to change from 
The type [null] is not the expected [EntityType] for the key class [class org.eclipse.persistence.example.jpa.server.business.Cell].
to something like 
No [EntityType] was found for the key class [class org.eclipse.persistence.example.distributed.collatz.model.UnitOfWork] in the Metamodel 
- please verify that the Entity class was referenced in persistence.xml using a specific
<class>org.eclipse.persistence.example.distributed.collatz.model.UnitOfWork</class>
property or a global <exclude-unlisted-classes>false</exclude-unlisted-classes> element.


Just a note that the fix for 338837 will be to help the user figure out why they are missing entity classes during deployment (they were not found) - by adding more warnings only.  The search path for entities will still be user or EJB-container (in the case of Java EE 5) controlled.
The user may wish to split entities among persistence units - this is why control is at the user level and where we do not want the API to pick up everything (unless specified) - however it is the cause of this unfortunate situation where you attempt to use something that is not known.
In the words of a certain public figure "it is unfortunate that we don't know what we don't know"
