An error occurred at line: 7 in the generated java file Syntax error on token "import", Identifier expected after this token An error occurred at line: 9 in the generated java file Syntax error on token "import", Identifier expected after this token 源代码如下：<%@ page language="java" import="java.util.*,,java.sql.*," pageEncoding="gbk"%>
<%@ page import="dao.DBConnection" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

PreparedStatement pstmt=null;
ResultSet rs=null;

   boolean flag=false;
   request.setCharacterEncoding("gbk");
   String id=request.getParameter("id");
