Target Unreachable, identifier (OBJECT) resolved to null

[codemonkey010101]

We cannot get past this error:

Target Unreachable, identifier '(OBJECT)' resolved to null

OBJECT is any class we implement with SEAM.  When referenced by the web form, it dies and dumps this error.  Here's an example not including the entity classes.  It's just implementing a simple search routine over a database object named Tcompany.  Currently, it's returning all rows from the Tcompany for testing.

Class:

@Stateful
@Name("TcompanyPersonList")
@Scope(ScopeType.SESSION)
public class TcompanyPersonList implements Serializable{
     
    @PersistenceContext
    EntityManager em;
    
    @DataModel
    List<Tcompany> searchResults;

    @DataModelSelection
    Tcompany selectedCompany;
    
    String searchString;

   
        
    public String getsearchString() {
        return searchString;
    }
    
    public void setsearchString(String searchString) {

         this.searchString = searchString;
    }

    @Begin(join = true)
    public String doSearch() {
         
         updateResults();
         return "";
         
    }
    
    private void updateResults() {
        
         try {
              
              List<Tcompany> results = em.createNativeQuery("from Tcompany c").getResultList();
              searchResults = results;
              
         } catch (Exception e) {
              searchResults = null;
         }        
    }
        
    
    @End
    public void reset() { }

    @Destroy
    public void destroy() { }
    
     
}

Anything type of object we implement returns the error.

I don't really understand where is your problem.

You SFSB must implements a Business Interface at least.
Don't you have an error telling you that ?

[codemonkey010101]

Yeah.  Let's throw out this thread.  I'm not getting consistant results with my configuration, as is.

Thanks for the reply.

You are defining a StateFul Session Bean (SFSB) Tcompanypersonlist.
Using SFSB forces you to declare a java interface.

interface Tcompanypersonlist {
   public doSearch() {.. what ever you need to to }
}

The interface should list all the methods you'd like to use in your web form.
By the way your get/set methods do not comply with the JavaBeans specification. The first letter after get/set should be uppercase.

Maybe this helps.

Same problem here, exposed in another thread.

My app was seam-Generated, giving the suitable getters/setters, and it also links the SFSB to its interface. It should work fine, exactly as the working examples, but it doesn't. I get that identifier 'whateverSFSB-name' resolved to null Error at every try...

Does anybody figured out what can be the problem for both of us ?

SEAMingly similar issue was solved : TargetUnreachableIdentifierDonorHomeResolvedToNull

SEAMingly similar issue was solved : TargetUnreachableIdentifierDonorHomeResolvedToNull

No, the solution there does not work.

No one knows a soluton to this issue?

This issue seems similar to what I'm experiencing with EntityQuery and have been posting in this forum for months about.

Seems that you placed the Seam Component class under the web project generated by the seam-gen, in which case the seam runtime did not recognized your components. if you place under the ejb project, it might work, at least, it works for me.
