jfreechart在linux下出现乱码，求解决办法

[yx580tnt]

用jfreechart显示的中文在中文linux下变成乱码，网上此问题的解决办法都是要改动linux下的文件，方法都比较复杂，有没在程序里直接改动的简单办法？
实在没有的话，有没通用点的办法？

[PoemCode]

这是linux版本JDK/JRE缺乏中文字体（支持）的缘故。（即便是最新的JDK1.5也是如此，真是奇怪SUN居然可以容忍这种问题一直延续到现在）。
以下是最简单的解决方法：
在JRE/lib/fonts下新建一个目录，命名为fallback,将winows下simsun.ttf字体拷贝到这个目录下。

谢谢，好像sun不怎么关心中国程序员的反馈，jdk文档官方翻译也是中国最后开始的。
我试试你的方法。

修正jre的font.conf文件也可以

[china2001ok]

怎么样?可以解决问题?

[yx580tnt]

PoemCode(诗意代码之魔数) 的方法中的simsun.ttf 没找到 只找到个微软的simsun.ttc ，试过不行，不知是不是什么地方还有问题

china_yx(笨木) 你说的font.conf我没找到阿，具体要改此文件的什么?

china2001ok(插花插花*不会插花) 我看不出什么错误，我把我的方法写出来吧

-----------------------
1) 找一个能在linux下用的中文字体，这里我找的是gbsn00lp.ttf
2) 把它放到jdk目录的jre/lib/fonts目录里
3) 修改/usr/j2sdk1.4.2_04/jre/lib/fonts/fonts.dir
a. 把第一行的数字加一 （如果是72就改为73）
b. 在最后新增一行
gbsn001.ttf -SungtiL GB-medium-r-normal--0-0-0-0-c-0-gb2312.1988-0
4) 修改/usr/j2sdk1.4.2_04/jre/lib/font.properties文件
把含有iso8859-1行从等号后面全部改为-SungtiL GB-medium-r-normal--0-0-0-0-c-0-gb2312.1988-0
（含有“CharToByteISO8859_1”的可以不改）

[china2001ok]

奇怪了 我重新换台机器 中文就能显示没问题的

不错，就是这个simsun.ttc，按照我的方法应该没有问题。在一些发行版中jre是可以找到中文字体。
