Jsp 请教问题

Question

 Jsp才入门
我在网上下了个源码    一个Access+Jsp做的论坛
http://www.7880.com/download/Access-4700.html 有下载我装的是Eclipse6.5+Tomcat6.0+JDK1.6
（分别安装在
    C:\Program Files\MyEclipse 6.5；
   C:\Program Files\Apache Software Foundation\Tomcat 6.0；
   C:\Program Files\Java\jdk1.6.0_16；
）
环境变量也都设置了。
把这个源码加压放到
..\workspace\bbs下试了  
但是有两个页面中文出现乱码incdb.jsp和incpages.jsp，用Tomcat运行   首页出错了
还请指教一下。

Answer 1

Eclipse6.5几年后才会出呢。现在最新的发布版是Eclipse3.5。
注：放下MyEclipse，投向Eclipse阵营吧，用Eclipse3.5开发web应用更方便，更合法。

Answer 2

乱码一般是编码方式造成的，一般在网页开头有个meta，后面有UTF-8和GB2312编码方式

Answer 3

配置一下你的TOMCAT编码跟页面编码统一

Answer 4

统一一下编码，最好都用utf-8

Answer 5

晕  我打错了  我用的是MyEclipse 6.5；window-preferences-workspace-text file encodeing 选择gb2312
incpages.jsp页面还是出错；
加了<%@ page contentType="text/html;charset=gb2312" %>也没用；
以下是incpages.jsp代码：
-------------------------------------
第一句<%function writeNull(){%>
<div align="center">

第三<%}%>-----------------------------
第一句就说 syntax error on token"function",new expected;
          unknown tag(jsp:directive.)
第二那里: systax error on token"}",delete this token.
第三句，也就是末尾：systax error,insert";" to complete Statement;
                 systax error ,insert"}" to complete Block;

是不是servlet的问题.... 要在xml文件里面修改？
