| StudentFasade bean = (StudentFasade) ctx | .lookup("StudentFasadeBean/remote"); | for (int i = 0; i < 10; i++) { | StudentBean stbean = new StudentBean(); | stbean.setName("Paata"); | stbean.setSurname("Lominadze"); | stbean.setAge(new BigDecimal(24)); | | GroupsBean gbean = new GroupsBean(); | gbean.setFaculty("Economic with Informatics"); | gbean.setGroupnumber(new BigDecimal(108940)); | gbean.setSpecial("Programming"); | | Integer retID = bean.addStudent(stbean, gbean); | System.out.println(retID); | } | } catch (NamingException e) { | e.printStackTrace(); | } | but i want run my client in other machine on the network using tomcat client code : | Properties jndiProps = new Properties(); jndiProps.setProperty(Context.INITIAL_CONTEXT_FACTORY, | "org.jnp.interfaces.NamingContextFactory"); jndiProps.setProperty(Context.URL_PKG_PREFIXES, | "org.jboss.naming:org.jnp.interface"); | jndiProps.setProperty(Context.PROVIDER_URL, "jnp://192.168.9.6:1099");
