在Java中可以使用如下判断支持的字体
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironm
ent();
String[] fontFamilies = ge.getAvailableFontFamilyNames();
for (String s : fontFamilies) {
System.out.println(s);
}
在jdk15以后,只需在~/jre/lib/fonts/下建一个fallback目录,把你想在java中使用的字体烤贝到这个目录中即可
以下方法在fc6下测试通过,假设用户的jre路径为 /usr/java/jdk1.6.0_03/jre/
#cd /usr/java/jdk1.6.0_03/jre/lib/fonts
#sudo mkdir fallback
将C:\WINDOWS\Fonts\simsun.ttc拷贝到 /usr/java/jdk1.6.0_03/jre/lib/fonts/fallback文件夹内 ok!

win7中没有,win2003 有simsun.ttc
