JNDI“无法实例化类:org.jboss.naming.remote.client.InitialContextFactory"

问题描述

我正在将 JBoss 服务器用于 EJB 我需要在控制台应用程序中使用 JNDI 来获取会话 bean 的引用，控制台应用代码看起来像这样

I'm using JBoss Server for EJB And I need JNDI in console app to get reference of session bean,console app code looks like this

import java.util.Properties;

import javax.naming.InitialContext;
import javax.naming.NamingException;


public class Program {

    public static void main(String[] args) throws NamingException {
        // TODO Auto-generated method stub
        Properties pr = new Properties();
        pr.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
        pr.put(InitialContext.PROVIDER_URL,"remote://localhost:4447");
        InitialContext ic = new InitialContext(pr);

    }

}

当我运行应用程序时出现异常

when I run the application I get exception

Exception in thread "main" javax.naming.NoInitialContextException: Cannot instantiate class: org.jboss.naming.remote.client.InitialContextFactory [Root exception is java.lang.ClassNotFoundException: org.jboss.naming.remote.client.InitialContextFactory]

推荐答案

您可以使用以下上下文进行连接.我已经尝试并测试来设置它.

You can use following context to connect.I have tried and tested to set up this.

import java.util.Properties;
import javax.naming.Context;
import javax.naming.NamingException;


public class Program {

    public static void main(String[] args) throws NamingException {
      Properties jndiProps = new Properties();
    jndiProps.put(Context.INITIAL_CONTEXT_FACTORY,
    "org.jboss.naming.remote.client.InitialContextFactory");
    jndiProps.put(Context.PROVIDER_URL,"remote://localhost:4447");
    jndiProps.put(Context.SECURITY_PRINCIPAL, "testuser");
    jndiProps.put(Context.SECURITY_CREDENTIALS, "testpassword");
    jndiProps.put("jboss.naming.client.ejb.context", true);
    Context ctx = new InitialContext(jndiProps);
    }

}

然后我得到这个错误

JBREM000200: Remote connection failed: javax.security.sasl.SaslException:
Authentication failed: all available authentication mechanisms failed - Could
not register a EJB receiver for connection to remote://localhost:4447
java.lang.RuntimeException: javax.security.sasl.SaslException: Authentication
failed: all available authentication mechanisms failed.

然后我使用 add-user.sh 添加了用户.

Then i added the user using add-user.sh.

握手成功消息来了.
