websphere jfreechart中文字体显示问题

Websphere jvm 设置中文试一下
-DLANG=zh_CN -Ddefault.client.encoding=GBK -Dfile.encoding=GBK -Duser.language=zh -Duser.region=CN

在基于WebSphere做Web开发的时候大多情况下会使用JFreeChart作为Web报表生成工具，但是在Unix平台上经常会出现中文输出乱码或者一个个小方块的情况。这个问题的解决方法如下：

1、JVM参数设置

     -Djava.awt.headless=true -Duser.language=zh -Duser.region=CN -Dfile.encoding=GBK -Dclient.override.encoding=GBK

2、用以下内容替换WebSphere自带的Java包（在java/jre/lib目录下）中的字体属性文件(font.properties)中的内容，但替换之间别忘记首先备份一下。

另外这个字体文件只适用于HP Unix系统。

以上方法同样适用于基于JFreeChart的JPivoit包的中文显示问题。
