How to configure JRE to run on specific font

Question

I've downloaded the java open source gui POS software and would like to change it to be able to display non-unicode font which include our local language.

I know that I can change the font of the gui components by component.setFont(new java.awt.Font("MyFont", 1, 14)) but there are a lot of components to change in order to make it display. Instead, I think changing the JRE default font will be a lot easy than changing the code.

According to Java Document, I've tried like the following so far - but it's not working.

Changed fontconfig.properties.src to fontconfig.properties under jre/lib/

In fontconfig.properties

Changed the font names to the one I want like this.

serif.plain.alphabetic=Times New Roman (=> serif.plain.alphabetic=MyFont)
sansserif.plain.alphabetic=Arial (=> serif.plain.alphabetic=MyFont)
monospaced.plain.alphabetic=Courier New (=> serif.plain.alphabetic=MyFont)
dialog.plain.alphabetic=Arial (=> serif.plain.alphabetic=MyFont)
dialoginput.plain.alphabetic=Courier New (=> serif.plain.alphabetic=MyFont)

and finally added this line.

filename.MyFont=MyFont.ttf

System Info:

Windows 7, jdk1.7.0

What am I doing wrong? Any advice would be very appreciated. Thank you :)

Solution

Also looking for a way to change the jre's default font, editing fontconfig.properties worked for me actually (oracle java 6, linux in my case):

• edit jre/lib/fontconfig.Ubuntu.properties

• To change the default font replace all DejaVu Sans with Ubuntu for example, and add the path to the font files:

  # Font File Names
  
  filename.Ubuntu=/usr/share/fonts/truetype/ubuntu-font-family/Ubuntu-R.ttf
  filename.Ubuntu_Bold=/usr/share/fonts/truetype/ubuntu-font-family/Ubuntu-B.ttf
  filename.Ubuntu_Oblique=/usr/share/fonts/truetype/ubuntu-font-family/Ubuntu-RI.ttf
  filename.Ubuntu_Bold_Oblique=/usr/share/fonts/truetype/ubuntu-font-family/Ubuntu-BI.ttf
  
  filename.Ubuntu_Mono=/usr/share/fonts/truetype/ubuntu-font-family/UbuntuMono-R.ttf
  filename.Ubuntu_Mono_Bold=/usr/share/fonts/truetype/ubuntu-font-family/UbuntuMono-B.ttf
  filename.Ubuntu_Mono_Oblique=/usr/share/fonts/truetype/ubuntu-font-family/UbuntuMono-RI.ttf
  filename.Ubuntu_Mono_Bold_Oblique=/usr/share/fonts/truetype/ubuntu-font-family/UbuntuMono-BI.ttf

Thank you for the answer. I search their forum and found out that pos is customized with look and feel. Does look and feel override the changes in code? I changed setFont method in java code but it did't take effect. Where am I start looking to change look and feel of that program?

I believe the look and feel sets the default, well, look and feel. For whatever reason, your code is having trouble changing the default.
