Question about jfreeChart in Linux

For details about jfreeChart in Linux, refer to general Linux technology-Linux technology and application information. Although the program yesterday solved the Chinese problem, the text in the charts generated by jfreeChart is still displayed as blocks, so I searched the internet again. There are many documents to discuss this problem, the solution is different, but most of them are different from my version. My system environment is Linux RedHat 9.0, tomcat5.5, and jdk1.5. Finally, the solution was found.

In jdk1.5, the order of loading the font configuration file is

(JavaHome refers to the root directory of JRE, the same below ):

JavaHome/lib/fontconfig. OS. Version. properties
JavaHome/lib/fontconfig. OS. Version. bfc
JavaHome/lib/fontconfig. OS. properties
JavaHome/lib/fontconfig. OS. bfc
JavaHome/lib/fontconfig. Version. properties
JavaHome/lib/fontconfig. Version. bfc
JavaHome/lib/fontconfig. properties
JavaHome/lib/fontconfig. bfc

1. First find the correct configuration file and find

Filename.-misc-zysong18030-medium-r-normal -- *-% d-*-c-*-iso10646-1 = ........

Make sure that the font file name and path are correct, for example:

Filename.-misc-zysong18030-medium-r-normal -- *-% d-*-c-*-iso10646-1 =/usr/share/fonts/zh_CN/TrueType/simsun. ttc

2. Rename the fontconfig file to fontconfig. RedHat. properties. Move all unnecessary files starting with fontconfig under $ JAVA_HOME/jre/lib to the newly created bak directory.

3. If there is no font, you can set the font file simsun. ttc (copy one copy from windows to linux, or use other fonts) copy to/usr/share/fonts/zh_CN/TrueType/(this path is the path specified in the configuration file above ).

4. edit the file fonts. dir in the JavaHome/jre/lib/fonts directory, add 1 to the number in the first line, and add the following to the last line:

Simsun. ttf-SungtiL GB-medium-r-normal -- 0-0-0-0-c-0-gb2312.1988-0

Save the file.

5. Restart the operating system.
