[jboss-user] [JNDI and Naming] - Re: lookup a session bean inside a servlet

stefano bertozzi [http://community.jboss.org/people/bertoz84] created the discussion "Re: lookup a session bean inside a servlet" To view the discussion, visit: http://community.jboss.org/message/603275#603275 -------------------------------------------------------------- Here's my BookShop ( EJB project ) structure:      - Book entity bean      - Utenti entity bean ( in english: Users )      - OperazioniUtenti stateless session bean ( in english: UsersOperations )      - OperazioniLibri stateless session bean ( in english: BooksOperations )      - Carrello stateful session bean ( in english: Cart )      - AccessoUtente stateful session bean ( in english: UserAccess ) this is the code: +package bookshop.library.sessionbean;+ +import java.util.Iterator;+ +import java.util.List;+ +import javax.ejb.Stateless;+ +import javax.ejb.TransactionAttribute;+ +import javax.ejb.TransactionAttributeType;+ +import javax.persistence.EntityManager;+ +import javax.persistence.PersistenceContext;+ +import bookshop.library.entitybean.*;+ +@Stateless+ +public class OperazioniUtenti implements OperazioniUtentiLocal{+ +          @PersistenceContext+ +          EntityManager em;+ +          public static final String RemoteJNDIName =  OperazioniUtenti.class.getSimpleName() + "/remote";+ +          public static final String LocalJNDIName =  OperazioniUtenti.class.getSimpleName() + "/local";+ +          public OperazioniUtenti() {+ +          }+ bla bla bla.... i have no problem in looking up it in my BookShop project ( inside AccessoUtente bean or in a simple testing java client ) Now again my somethingServlet inside my Web project: +package webinterface.servlet;+ +import java.io.IOException;+ +import java.io.PrintWriter;+ +import javax.naming.Context;+ +import javax.naming.InitialContext;+ +import javax.naming.NamingException;+ +import javax.servlet.RequestDispatcher;+ +import javax.servlet.Servlet;+ +import javax.servlet.ServletException;+ +import javax.servlet.http.HttpServlet;+ +import javax.servlet.http.HttpServletRequest;+ +import javax.servlet.http.HttpServletResponse;+ *+import bookshop.library.entitybean.*;+* *+import bookshop.library.sessionbean.*;+* +public class somethingServlet extends HttpServlet+ +implements Servlet {+ +           static final long serialVersionUID = 1L;+ +           static Context context;+ +           static OperazioniUtenti opUser;+ +           static Utenti user;+ +          public somethingServlet() {+ +                         super();+ +          } + +protected void doPost(HttpServletRequest request, HttpServletResponse response)+ +throws ServletException, IOException {+ +                    try+ +                    {+ +                                   context = new InitialContext();+ +*                                   System.out.println(OperazioniUtentiLocal.class.toString());* // print successfully INFO  [STDOUT] interface bookshop.library.sessionbean.OperazioniUtentiLocal+ *+                                   opUser = (OperazioniUtenti) context.lookup("/BookShop/OperazioniUtenti/local");+* +                    } catch (NamingException e) {+ +                                   e.printStackTrace();+ +                    }+ bla bla bla... ( ....I switched to Local from Remote....). Lookup returns a null pointer because it can't find BookShop. I read a lot about this problem but the best answer i found says to put my BookShop.jar inside MYWEBPROJECTPATH/WebContent/WEB_INF/lib and be sure to have it in the java build path of the web project ( that's what i did ).
