我的文件目录:

project/src/m2mcom/entities/AutomatedTelnetClient.java
           /web/Simple.java           
           /org/apache/commons/net/telnet/TelnetClient.java 

Simple.java的源代码:

package m2mcom.web;
import m2mcom.entities.AutomatedTelnetClient;
import java.util.*;
import java.io.*;

public class Simple {
    public static void main(String [] args) {
        try {
            AutomatedTelnetClient telnet = new AutomatedTelnetClient();
            String answer = telnet.request();
            System.out.println(answer);
        } catch (Exception e) {
            System.err.println("Error");
        }
    }
}

当我执行Simple.class,没有任何编译错误时,我收到此错误消息:

C:\Users\Victor\Desktop\project2\src\m2mcom\web>java Simple
Exception in thread "main" java.lang.NoClassDefFoundError: Simple (wrong name: m
2mcom/web/Simple)

有谁知道如何解决这个问题？

我想看看MSGTEXT表中重复多少次MMOUTBOUND.为此,我使用以下查询:

SELECT 
    MSGTEXT, 
    COUNT(*) TotalCount 
FROM MMOUTBOUND 
GROUP BY MSGTEXT 
HAVING COUNT(*)>1;

但是我收到错误,因为ntext数据类型无法进行比较或排序.如何为ntext数据类型实现此目的？

我有以下源代码:

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
s.bind(('', 9800))
try:
    while True:
        data, addr = s.recvfrom(256) #buffer size is 256 bytes
        print data, adrr
finally:
    s.close()

当我执行它时,我收到以下错误:

Traceback (most recent call last):
   File "socket.py", line 1, in 
     import socket
   File "C:\Users\Victor\Desktop\socket.py", line 3, in 
     s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
AttributeError: 'module' object has no attribute 'AF_INET'

我怎么解决这个问题？
