HHH015011: Unable to locate static metamodel field

K A Newbie

Hi,

 

I started porting an JEE5 application from JBoss 4.2 to JBoss 7.1.1 today. Everything has gone quite nice but one thing; when I am deploying the application I get an error log saying something like:

 

HHH015011: Unable to locate static metamodel field : com.myapp.MyEntity_#mMyField

 

The class is annotated with @MappedSuperclass and looks something like this:

 

@MappedSuperclass

public class EternalEntity {

 

   @Basic

   @Column(name="active")

   private String mMyField;

  

   public String getMyField() {

      return mMyField;

   }

 

   public void setMyField(String myField) {

      mMyField = myField;

   }

}

 

Everything works ok in JBoss 4.2. Has anyone seen this error before and knows how to solve it?

 

Thanks in advance

 

/KA

    Hi Everyone,

    Exacty the same thing is happening to me.

    Moreover,

    Also this happens with @Embeddables objects mapped within @Entities.

    Please attach the entire exception callstack for this.

    Please attach the  exception callstack for the @Embeddables case also.

    Hi, Scott

    These are the issues we are facing with criteria/metamodel APIs and Jboss-as-7.1.0

     

    As you can see from the attached example (zip file), we are extending an @Entity (TaxAgent) from a @MappedSuperclass (Agent)

    Agent has an @Embedded attribute (document), and this generates two errors:

     

    1. When deploying there "Unable to locate static metamodel field" errors. Note that this errors act at two levels, first the document field cannot be found in TaxAgent_ but also, the documentType field cannot be found inside our embeddable, Document_.

     

    2. When trying to create a path expression from the root object (taxAgent) to TaxAgent_.document an exception is thrown (which is below).

     

    3. Also, we've found this:

    https://hibernate.onjira.com/browse/HHH-5024 (which is similar but a different hierarchy @Embeddable extending a @MappedSuperclass)

     

    4. At "deploy" time the logger error message as below:

    17:15:01,452 ERROR [MetadataContext] Unable to locate static metamodel field : agents.TaxAgent_#document

    17:15:01,457 ERROR [MetadataContext] Unable to locate static metamodel field : stuff.Document_#documentType

     

    5. At query time:

    public final List<TaxAgent> getList(final String description)

    {

        List<TaxAgent> taxAgentList = null;

        try

        {

            final CriteriaBuilder cb = em.getCriteriaBuilder();

            final CriteriaQuery<TaxAgent> cq = cb.createQuery(TaxAgent.class);

            final Root<TaxAgent> taxAgent = cq.from(TaxAgent.class);

     

            // <- This is the exception line: at service.manager.ejb.TaxAgentManagerEJB.getList(TaxAgentManagerEJB.java:61) [:]

            final Path<Document> document = taxAgent.get(TaxAgent_.document);

     

            //    final Path<Document> document = taxAgent.get("document"); // <- This works (just in case you were asking)

            final Path<String> documentNumber = document.get(Document_.documentNumber);

            final StringBuilder sb = new StringBuilder();

     

            sb.append("%").append(description.trim().replaceAll(" ", "%")).append("%");

            cq.where(cb.like(cb.upper(cb.trim(documentNumber)), sb.toString().toUpperCase()));

     

            // Gets data.

            final TypedQuery<T> tq = em.createQuery(cq);

            taxAgentList = tq.getResultList();

        }

        catch (Throwable t)

        {

            throw new EJBException(t.getMessage());

        }

        return taxAgentList;

    }

    Hi Mariano,

     

    Did you attach the wrong exception callstack above?  That looks like a null pointer exception instead of an "Unable to locate static metamodel field" error.

     

    Also, see if you can reproduce with the nightly AS7 build.

    Hi Scott,

    I've attached both:

     

    1. Error al deploy time (see point 4 about "Unable to locate static metamodel field")

    2. Error at execution/query time (see point 5,6)

     

    Kind Regards !

  • 8. Re: HHH015011: Unable to locate static metamodel field
    Scott Marlow Master

    So, the "Unable to locate static metamodel field" appears during deployment?  Could you attach or paste some output from deployment that shows that.

  • 9. Re: HHH015011: Unable to locate static metamodel field
    Mariano Kocalka Machala Newbie

    Thoughts,

     

    About errors at deploy time (static metamodel fields not found), seems like the app server is complaining when either:

    a. Class "B" extends class "A" and class "A" is defined as @MappedSuperClass

    b. Class "B" embed a property of type "X" where "X" is defined as @Embeddable.

     

    No matter with that, the application server log these errors (at deploy time) but the EAR application keep up and running.

     

    Therefore, the thing is:

    a. We want to build jpa2 criterias queries filtering by those missing fields (see attached code: Agent, TaxAgent, Document, DocumentType and also see sample query code at point 5)

    b. If path expresions are built over static metamodel properties the query throws a NPE (and makes sense since at deploy time the appserver has signaled that some static metamodel fields were missing)

    c. If path expresions are built over "strings" (bypassing static metamodel properties) the query is executed without errors (but this is just a fix/workaround and should not be used in this way)

     

    Hope this help in order to describe the issue we are facing.

     

    Let me know your thoughts,

    Regards !

    I'm not sure of the cause.  I asked about this problem and there are a few issues (some related to HHH-5024). 

     

    From a recent IRC discussion about this:

    Part of the problem is that there are just lots of incorrect mappings that crop up there.  People trying to override mapping information incorrectly.  More defensive checking is really what is needed there.

     

    I suspect that it might be easier for you to help contribute a Hibernate patch/fix to add the defensive error checking.

    Hi Scott,

    Sorry for the delay.

    Thank you very much for the suggestion, im affraid this could be the only way, the thing is that issue is opened since 2010.

    Regards!

    Hi Mariano,

     

    If you are interested in helping with a Hibernate patch, you could subscribe to https://lists.jboss.org/mailman/listinfo/hibernate-dev and ask for guidance on where the code changes should go.

     

    The short term plans for further metamodel development are discussion in an IRC meeting here (from #hibernate-dev on freenode).

    Thanks again Scott,

    I'll follow the hibernate dev list as soon as possible.

    cheers!
