生成exe文件后出现的问题

[CN40618]

各位大侠:

小弟的测试的过程中,
需要上传文件过数据库.
public class DBFactory {
private static String CLASSNAME =
"com.microsoft.jdbc.sqlserver.SQLServerDriver";
private static String databaseURL =
"jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=DatabaseName";
private static String user = "sa";

//private static String password = "";
private static String password = "";

private static DatabaseDAO factorydao = null;

//是否是第一次联接，做报错提示使用
public static boolean isfirstcon = true;

public static boolean stop = false;

static ConnectionFactory cf = null;
..........
}
测试程序运行没有问题,但是生成exe文件后,运行exe文件
就出现如下问题.提示是:
C:\Documents and Settings\hua\桌面\11111.txt
connection factory 创建！

jar文件路径的问题；exe默认exe文件所在的目录是当前目录，sqlserver的三个lib包的应该在当前目录下寻找
