JBuilder＋weblogic6.1＋EJB出现问题，EJB已经成功部署，但运行客户端程序报错，请高手帮忙！

[caserry80]

我已经将JBulier和weblogic6.1连接了起来，我做了一个会话EJB的简单的例子，就是为了输出helloworldEJB已经成功编译成了JAR文件，并部署到了weblogic上，但是我在用客户端程序调用的时候，运行有错误，有如下提示：

Exception in thread "main"


我的客户端程序如下：
package com.learnweblogic.examples.ch8.helloworld;

import javax.naming.Context;
import javax.naming.NamingException;
import javax.rmi.PortableRemoteObject;

public final class HelloWorldClient extends BaseClient {

private Context ctx;

HelloWorldClient(String [] argv)
throws NamingException
{
super(argv);

ctx = getInitialContext();

}

public void runClient()
throws Exception
{

HelloWorldHome home = null;

try {
Object h = ctx.lookup("HelloWorld");

home = (HelloWorldHome)
PortableRemoteObject.narrow(h, HelloWorldHome.class);
} catch (NamingException ne) {
System.err.println("Unable to lookup the HelloWorld EJB.");
System.err.println("Please make sure that the bean has been deployed"+
", and the client's classpath has been set correctly.");

throw ne;
}

try {
HelloWorld hw = home.create();

System.out.println("Say Hello to EJB.");

String ejbSays = hw.helloWorld();

System.out.println("The EJB said: "+ejbSays);
} catch (Exception e) {
System.err.println("Received an unexpected exception " + e
+ " while using the HelloWorldEJB.");

throw e;
}
}

public static void main(String[] argv)
throws Exception
{
HelloWorldClient hwc = new HelloWorldClient(argv);

hwc.runClient();

}
}
请问是哪里错了？？

Cause(错误引起的原因)
The test client is unable to communicate with WebLogic server.

Solution（解决方案）
Note that the PROVIDER_URL to connect to WebLogic server is hardcoded in the test client.
The hardcoded value is t3://localhost:7001. If you have started your WebLogic server
in another hostname or port number, for any reason, change this value to match the new
values.

没有得到WebLogic上下文环境所致。解决方案同楼上所示。

被楼上抢先了。

没有连上数据源

没有连上数据源?
---不会吧，HelloWorld还要数据源，老兄昨天没睡好吧！哈哈！

是jndi的问题，
加上这个：

Context.INITIAL_CONTEXT_FACTORY
"weblogic.jndi.WLInitialContextFactory"
Context.PROVIDER_URL
"t3://127.0.0.1:7001"
