hi ,
i got in project i call the ejb this way
|
| Properties props = new Properties();
|
props.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
| props.setProperty("java.naming.provider.url", "jnp://192.168.0.10:1099");
| props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");
| props.setProperty("jnp.socket.Factory",
"org.jnp.interfaces.TimedSocketFactory");
| Context context = new InitialContext(props);
|
| TraxManager TraxManager =
(TraxManager)context.lookup("TraxService/remote");
|
the problem is that i got this line:
| TraxManager TraxManager =
(TraxManager)context.lookup("TraxService/remote");
|
instanciated in each of my managed bean .... (i'm using jsf) , it's not optimal
like solution
so i have created a generic class :
| package com.voipover.utils;
|
| import java.util.Properties;
|
| import javax.naming.Context;
| import javax.naming.InitialContext;
| import javax.naming.NamingException;
|
| public class EJBHomeFactory {
|
|
|
| public static Object lookup(String jndiName) {
| Context context = null;
| try {
| Properties props = new Properties();
|
props.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
|
props.setProperty("java.naming.provider.url", "jnp://192.168.0.10:1099");
|
props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");
| props.setProperty("jnp.socket.Factory",
"org.jnp.interfaces.TimedSocketFactory");
| context = new InitialContext(props);
| //context = new InitialContext();
| return context.lookup(jndiName);
| } catch (NamingException ex) {
| throw new IllegalStateException("Cannot connect to
bean: " + jndiName + " Reason: " + ex, ex.getCause());
| } finally {
| try {
| context.close();
| } catch (NamingException ex) {
| throw new IllegalStateException("Cannot close
InitialContext. Reason: " + ex, ex.getCause());
| }
| }
| }
|
| }
|
so now i'm trying to call my service like that :
| TraxManager TraxManager = (TraxManager)
EJBHomeFactory.lookup("TraxService/remote");
|
but when i test receive the following error :
| Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad
