java - 实例化 InitialContextFactory 失败

Question

我尝试寻找无法实例化 InitialContextFactory 的解决方案，但他们的答案似乎不起作用，我尝试在 JBoss 6 EAP 和 JBoss 7 AS 上运行它，所以看来我做错了。

这就是我初始化InitialContext的方式:

public static Context getInitialContext( )
    throws javax.naming.NamingException {

        Properties p = new Properties( );
        p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
        p.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
        p.put(Context.PROVIDER_URL, "jnp://localhost:1099");
        return new javax.naming.InitialContext(p);
    }  

这是堆栈跟踪:

在应用服务器内，您所要做的就是new InitialContext()，不带任何参数。应用服务器已为 JNDI 预先配置了适当的属性。
