jsp中config.java文件的public String systemURL该怎么写

作者：未知 来源：月光软件站 加入时间：2005-5-13　月光软件站

我下了个jsp 网站的源代码上面说只修改config.java 和config,jsp就可以运行

我该了几次都不行。大家帮忙看看。

config.java源文件：

package myshop;

public class config {
 //--- 关于数据库的设置 ---
 public String DBdriver = "org.gjt.mm.mysql.Driver";
 public String DBname = "503room";
 public String DBuser = "503room";
 public String DBpwd = "503room";
 public String DBurl = "jdbc:mysql://localhost:3306/" + DBname + "?user=" + DBuser + "&password=" + DBpwd;

 public String systemURL =   "http://localhost:8080/myshop";
 public String systemFolder = "/myshop/";
}

运行的错误提示：
