weblogic ejb3报错

Question

Bean类:package com.huawei.ejb;import javax.ejb.Local;
import javax.ejb.Remote;
import javax.ejb.Stateless;@Stateless(mappedName="HelloBean")
@Remote(Hello.class)
@Local(Hello.class)
public class HelloBean implements Hello {

public String say(String name) {
return "Hello " + name;
}}
客户端:package com.huawei.ejb.client;import java.util.Properties;import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;import com.huawei.ejb.Hello;public class HelloEjbClient {

public static void main(String[] args) throws NamingException{
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
properties.put(Context.PROVIDER_URL, "t3://127.0.0.1:7001");
Context context = new InitialContext(properties);
Hello hello = (Hello)context.lookup("HelloBean/remote");
String returnValue = hello.say("renci");
System.out.println(returnValue);
}}
weblogic已经部署成功但是执行就是报错Exception in thread "main" javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:

找到答案了,将WebLogic.jar放在classpath的第一位就可以解决这个问题但是现在又遇到问题了Exception in thread "main" javax.naming.NameNotFoundException: While trying to lookup 'HelloBean.remote' didn't find subcontext 'HelloBean'. Resolved '' [Root exception is javax.naming.NameNotFoundException: While trying to lookup 'HelloBean.remote' didn't find subcontext 'HelloBean'. Resolved '']; remaining name 'HelloBean/remote'

WebLogic已经部署成功了,而其配置的数据源都可以找到,ejb怎么就找不到呢???

问题搞定,原因是没有写weblogic-ejb-jar.xml
客户端也写错了/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */package ejbtest;import com.renci.ejb.Hello;
import java.sql.SQLException;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;/**

public class Main {
    public static void main(String[] args) throws NamingException, SQLException{
        Properties properties = new Properties();
        properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
        properties.setProperty(Context.PROVIDER_URL, "t3://127.0.0.1:7001");
        properties.setProperty(Context.SECURITY_PRINCIPAL, "weblogic");
        properties.setProperty(Context.SECURITY_CREDENTIALS, "renci418037077");
        Context context = new InitialContext(properties);
        Hello hello = (Hello)context.lookup("HelloBean#com.renci.ejb.Hello");
        String returnValue = hello.say("renci");
        System.out.println(returnValue);
    }
}

不太清楚，是配置开发环境还是Weblogic运行环境了。
         找到答案了,将WebLogic.jar放在classpath的第一位就可以解决这个问题
