I have a session bean

@Stateless

public class SampSess implements SampLocal, SampRemote {

    @PersistenceContext(unitName="mydb")

    EntityManager em;

    private ProductDTO toDto(ProductTO prod){

      ProductDTO ret = new ProductDTO();

      ret.setProdId(prod.getProdId());

      ret.setProdName(prod.getProdName());

      ret.setProdCost(prod.getProdCost());

      return ret;

    }

    private ProductTO toTo(ProductDTO prod){

        ProductTO ret = new ProductTO();

        ret.setProdId(prod.getProdId());

        ret.setProdName(prod.getProdName());

        ret.setProdCost(prod.getProdCost());

        return ret;

    }

    @Override

    public boolean saveProduct(ProductTO prod) {

        boolean ret = false;

        ProductDTO forSave = this.toDto(prod);

        try{

         em.persist(forSave);

         ret = true;

        }catch(Exception e){

           e.printStackTrace();

        }

        return ret;

    }

    @Override

    public ProductTO searchProduct(int prodId) {

        ProductTO ret = new ProductTO();

        try{

          ProductDTO dto = em.getReference(ProductDTO.class, new Integer(prodId));

          ret = this.toTo(dto);

        }catch(Exception ex){

          ex.printStackTrace();

        }

        return ret;

    }

    public SampSess() {

    }

    public String hello(String str) {

       return "Hello hi "+ str.toUpperCase();    

    }

}

deployed as a part of ear

and web delegate looking up for this

String deployName = "java:global/myProj/SessEx/SampSess!htcejbs.SampLocal";

  public SampLocal getSampLocal(){

    SampLocal  local = null;

    try{

        final Properties jndiProperties = new Properties();

        jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

        final Context ctx = new InitialContext(jndiProperties);

        local = (SampLocal)ctx.lookup(deployName);

    }catch(Exception ex){

         ex.printStackTrace();

    }

    return local;

  }

but in running shows an error

java.lang.ClassCastException: htcejbs.SampLocal$$$view2 cannot be cast to htcejbs.SampLocal
