卡卡的梦

  原先，我的从sql中读shu据的java程序可以正常运行，当我重新配置了weblogic下的application时，再编译我的這个java程序（在命令窗的環境zhong），打出三个"cannot resolve symbol"的错误.我在classpath中已设置了类路徑:c:\myjava,放openSql类的dbbean包就在myjava中.并且数据源也配好了(同yuan来一样).各位高手,能帮我分析一下原因吗?谢谢!
cannot resolve symbol
symbol：class openSql
location：package dbbean
import dbbean.openSql;

cannot resolve symbol
symbol：class openSql
location：myjava.rdrzdtj1
openSql c=new openSql();
cannot resolve symbol
symbol：class openSql
location：class myjava.rdrzdtj1
openSql c=new openSql();
原程序:

package myjava;
import java.io.*;
import java.util.*;
import java.util.Date;
import java.text.*;
import dbbean.openSql;
import java.sql.*;
public class rdrzdtj1
{
public static void main(String[] args){
     try{
String[]strSQL=new String[23];
      
strSQL[0]="SELECT Zdz From drzdtj WHERE Ycxh='1'";
strSQL[1]="SELECT Zdz From drzdtj WHERE Ycxh='2'";
strSQL[2]="SELECT Zdz From drzdtj WHERE Ycxh='3'";

    int i;
