为什么要写成那样那个的servlet呢？？
不如直接写个方法然后调用

----------------解决方案--------------------------------------------------------
你试一下：
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
String url="jdbc:mysql://localhost:3306/JavaWeb?useUnicode=true&characterEncoding=gb2312";
connection con=DriverManager.getConnection(url,"root","root");
Statement stmt=con.createStatement();

第十七行少了分号

现在是连接不上的问题。不要说方法好不

回复楼主 zacom

看我这个

//1、MySQL数据库
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1"
//myDB为数据库名
Connection conn= DriverManager.getConnection(url);
