一。文本校验，因为要工作在window,linux,所以用java写app

package com.cttmis;

import java.io.*;
import java.util.*;
import java.text.SimpleDateFormat;

/**
因为客户导入的数据经常有一些错误，为了自动检查文件而开发
20070907
parm:文件所在路径 体积限制(M为单位)
cmd: java com.cttmis.checktxt 目录 体积限制(300)
异常一：行数据不完整。校验逗号分隔符号(,)的数量是否一致。(中间折行的也能校验出)
异常二：存在空行
我现在发现的错误是字符字段切断形成乱码而造成的。

二。bat批处理(window下)

1. 不输出文本，只作屏幕显示：

@@echo off

set path = "%path%;C:/Program Files/Java/j2re1.4.2_04/bin"

java -classpath "%classpath%;." com.cttmis.checktxt E:/FTPFILE
pause

2. 作检查并输出到err.log

@@echo off

set path = "%path%;C:/Program Files/Java/j2re1.4.2_04/bin"

java -classpath "%classpath%;." com.cttmis.checktxt E:/FTPFILE >>err.log
pause

//Note: "%classpath%;." 后面的点代表当前路径，这样不用关心class文件的路径名。

//这是一个习作，是学习java的第一个程序。也许有不足的地方。
