帮忙看看，在weblogic6.1上的部署文件是否正确？

[javaren]

<?xml version="1.0"?>

<!DOCTYPE weblogic-ejb-jar PUBLIC '-//BEA Systems, Inc.//DTD WebLogic 5.1.0 EJB//EN' 'http://www.bea.com/servers/wls510/dtd/weblogic-ejb-jar.dtd'>
<!--EJB部署说明文件-->
<weblogic-ejb-jar>
<weblogic-enterprise-bean>
<!--EJB名-->
<ejb-name>MyFirstEJB</ejb-name>
<!--定义EJB最大缓冲池-->

<max-beans-in-free-pool>100</max-beans-in-free-pool>
</caching-descriptor>
<!--定义EJB jndi名称-->
<jndi-name>HelloHome</jndi-name>
</weblogic-enterprise-bean>
</weblogic-ejb-jar>

我的第一个程序总调试不出来，我感觉是部署文件的事
尤其是
<!DOCTYPE weblogic-ejb-jar PUBLIC '-//BEA Systems, Inc.//DTD WebLogic 5.1.0 EJB//EN' 'http://www.bea.com/servers/wls510/dtd/weblogic-ejb-jar.dtd'>

基本上面的连接就可以完成了！！！

没有异常。编译通过，但就是用客户端测试时不行。

我把文件都出贴来，大家帮忙看看，非常简单是hello ejb！

hello.java

//本接口需要引入的类或接口
import javax.ejb.EJBObject;
import java.rmi.RemoteException;

//定义远程接口，必须继承EJBObject
public interface Hello extends EJBObject {
//定义业务逻辑方法
public String sayHello()
throws RemoteException;
}


HelloHome.java

//本接口需要引入的类或接口
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;

//定义主接口，必须继承EJBHome
public interface HelloHome extends EJBHome {
//定义EJB创建方法
Hello create() throws CreateException, RemoteException;
}


HelloBean.java

//本类需要引入的类或接口
import javax.ejb.CreateException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;

//实现业务逻辑，必须实现SessionBean接口
public class HelloBean implements SessionBean {
//这是个会话EJB，声明会话上下文
private SessionContext ctx;
//声明字符串
private String words;
//接口SessionBean中定义的方法，必须实现
public void setSessionContext(SessionContext ctx) {
this.ctx = ctx;
}
//接口SessionBean中定义的方法，必须实现
public void ejbActivate() {
}
//接口SessionBean中定义的方法，必须实现
public void ejbPassivate() {
}
//接口SessionBean中定义的方法，必须实现
public void ejbRemove() {
}
//和主接口定义对应的方法，必须实现
public void ejbCreate() throws CreateException {
words = "Hello World";
}
//供客户端调用的业务逻辑方法，这里只简单的打印字符串，并把字符串返回到客户端
public String sayHello()
{
System.out.println("I am in an EJB of Server ."+words);
return words;
}

大家帮忙看看，在线等待，200分相送！

[javaren]

运行结果：

c:\work\hello\client>java HelloClient t3://localhost:7001
客户端程序测试结束...

c:\work\hello\client>

为什么没显示结果？大家多多帮忙啦！一定给分
