JSP文件错误，哪里错了

Question

org.apache.jasper.JasperException: 无法为JSP编译类:

JSP文件：[/tj.jsp] 的第 [120] 行发生了一个错误
System.out cannot be resolved to a type
117: if(member==null)member=ipaddress;
118: String sql="select count(*) from keyword where member='"+member+"' ";
119: String sql2="select * from keyword where member='"+member+"' order by id desc";
120: System.out.println(sql2);
121: news.setEVERYPAGENUM(12);
122: int cou = news.getMessageCountSs(sql);//得到信息总数
123: String page1=request.getParameter("page");

Answer 1

找不到System.out，应该是项目jdk环境没有配置好，缺少jar包。
