    Dasari Prasad Newbie

      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;

        }
