我很纠结 ，不知道是哪里的问题，感谢各位给予帮助，谢谢！！ --------------------编程问答-------------------- 你的reply.jsp页面里是不是没有页面跳转啊 --------------------编程问答-------------------- --------------------编程问答--------------------
<from action="replyDeal.jsp" method="post">
</from>
这里怎么写成from了？是form
另外，倒底是replyDeal.jsp？还是reply.jsp哩？ --------------------编程问答-------------------- <from action="replyDeal.jsp" method="post">
红色地方是不是写错了
应该是action="replyDe.jsp"页面吧 --------------------编程问答--------------------
楼主太粗心，而且出现错误的时候缺乏耐心检查代码 --------------------编程问答-------------------- 谢谢， 楼主说的是， 我还是初学者。我以后一定注意!! --------------------编程问答-------------------- 但是又出现问题了
An error occurred at line: 18 in the jsp file: /replyDeal.jsp
conn cannot be resolved to a variable
15: Connection c = DB.getConn();
16:
17: String sql = "insert into article values (null, ?, ?, ?, ?, now(), ?)";
18: PreparedStatement pstmt = DB.prepareStmt(conn, sql);
19: pstmt.setInt(1, pid);
20: pstmt.setInt(2,rootId);
21: pstmt.setString(3, title);
An error occurred at line: 29 in the jsp file: /replyDeal.jsp
conn cannot be resolved to a variable
26:
27:
28: DB.close(pstmt);
29: DB.close(conn);
30:
31: %>
32:
我还是检查不出来，谢谢各位帮忙检查一下！！ --------------------编程问答-------------------- Connection 连接失败，数据库jar包是否导入？ --------------------编程问答-------------------- PreparedStatement pstmt = DB.prepareStmt(conn, sql);
改成
PreparedStatement pstmt = DB.prepareStmt(c, sql);
因为你这里定义的变量名是 c : Connection c = DB.getConn(); --------------------编程问答-------------------- 不得行，谢谢了！！ --------------------编程问答-------------------- 我的现在已经行了，我什么也没改，就是重写了一遍就行了，我郁闷呀，花了我几个小时的时间!! --------------------编程问答-------------------- 问题解决了吗 --------------------编程问答-------------------- 问题解决了，谢谢！！
补充：Java , Web 开发
