myeclipse下的web应用
有一个登录注册功能，登陆的时候读取数据库可以，
但是注册要写入进去就不行
register.jsp

String sql = "use jsgl;insert into jsgl.user values('"+name+"','"+account+"','"+pswd1+"','"+pswd2+"')";
System.out.println("执行到了");
Connection conn=DB.getConn();
System.out.println("执行到了");
Statement stmt = DB.createStmt(conn);
System.out.println("执行到了");
int n = DB.executeUpdate(stmt, sql);
response.sendRedirect("index.jsp");
System.out.println("执行到了");
}
