I successfully deployed a simple EJB 3. Here is the code: {code} package ejb; import javax.ejb.Remote; @Remote public interface HelloWorld {     public String sayHello(); } package ejb; import javax.ejb.Stateless; import ejb.HelloWorld; public @Stateless class HelloWorldBean implements HelloWorld {     public String sayHello()     {         return "Hello world...";     } } {/code] The deployment tells me about the following bindings: {code}   java:global/MyEJBProject/HelloWorldBean!ejb.HelloWorld   java:app/MyEJBProject/HelloWorldBean!ejb.HelloWorld   java:module/HelloWorldBean!ejb.HelloWorld   java:jboss/exported/MyEJBProject/HelloWorldBean!ejb.HelloWorld   java:global/MyEJBProject/HelloWorldBean   java:app/MyEJBProject/HelloWorldBean   java:module/HelloWorldBean {/code} Looking up from a standalone client works: {code} import java.util.Properties; import javax.naming.Context; import javax.naming.InitialContext; import ejb.HelloWorld; import ejb.HelloWorldBean; public class Client {     public static void main(String[] args) {         try {             Properties env = new Properties();             env.put(Context.INITIAL_CONTEXT_FACTORY,                     "org.jboss.naming.remote.client.InitialContextFactory");             env.put(Context.PROVIDER_URL, "remote://localhost:4447");             env.put(Context.SECURITY_PRINCIPAL, "xxx");             env.put(Context.SECURITY_CREDENTIALS, "xxx");             env.put("jboss.naming.client.ejb.context", true);             Context ctx = new InitialContext(env);             HelloWorld hello = (HelloWorld) ctx.lookup("MyEJBProject/HelloWorldBean!ejb.HelloWorld");             System.out.println("EJB says: " + hello.sayHello());         } catch (Exception e) {             e.printStackTrace();         }     } } {/code} But invocation from a servlet results in error messages due to unsuccessful lookups. I tried: {code} protected void doGet(HttpServletRequest request,         HttpServletResponse response) throws ServletException, IOException {     try {         response.setContentType("text/plain");         PrintWriter out = response.getWriter();         Context ctx = new InitialContext();         HelloWorld hello = (HelloWorld) ctx                 .lookup("MyEJBProject/HelloWorldBean!ejb.HelloWorld");         out.println("EJB says: " + hello.sayHello());     } catch (Exception e) {         e.printStackTrace();     } } {/code} Any idea? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/772525#772525] Start a new discussion in EJB3 at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
