I have added a font to my JAR file from eclipse and am trying to use the font within JTextFields. The setText isn't being drawn when I run the application, just a - in the JTextField. I based my code off Exporting font to jar in eclipse .
Below is my code:
//lets load the font
Font font = Font.createFont(Font.TRUETYPE_FONT, Main.class.getClassLoader().getResourceAsStream("Coalition_v2.ttf"));
font.deriveFont(Font.PLAIN, 14);
txtBrain = new JTextField();
txtBrain.setFont(font);
txtBrain.setText("BRAIN");
txtBrain.setHorizontalAlignment(SwingConstants.CENTER);
txtBrain.setEditable(false);
txtBrain.setColumns(10);
txtBrain.setBounds(521, 727, 90, 40);
contentPane.add(txtBrain);
I know the font is in the correct place as if I change the .getResourceAsStream to /Coalition_v2.ttf then I get the following error from the console:
java.io.IOException: Problem reading font data.
at java.awt.Font.createFont(Font.java:946)
The Font file is contained within /src/
Output of Jar -tvf as requested:

The code is being run from Main.class.
EDITED:
Code now looks like this:
Font font = Font.createFont(Font.TRUETYPE_FONT, this.getClass().getResourceAsStream("/Coalition_v2.ttf")).deriveFont(Font.PLAIN, 14);
System.out.println(font)
Sorted. Thanks for your help, and Andrew for your steer in the right direction.
Change
.. Main.class.getClassLoader().getResourceAsStream("Coalition_v2.ttf") ..
..to something more like..
.. this.getClass().getResource("/Coalition_v2.ttf") // note leading '/' ..
..for an URL then print it out to check it is found.
The leading /
means 'look for the root of the class-path' as opposed to from the current package or directory.
There is pretty strange exception handling in createFont method. If FontFormatException or IOException catched, then it just rethrown. In all other cases will be rethrown:
throw new IOException("Problem reading font data.");
So your actually issue is even not the IO problem.
First of all take a look at this point. There is such code in this method:
final File tFile = AccessController.doPrivileged(
new PrivilegedExceptionAction<File>() {
public File run() throws IOException {
return File.createTempFile("+~JF", ".tmp", null);
}
}
);
It tries to write into temp directory. You should check if your programm have access to do that.
Solution in case anyone finds this from google was:
Font font = Font.createFont(Font.TRUETYPE_FONT, this.getClass().getResourceAsStream("/Coalition_v2.ttf")).deriveFont(Font.PLAIN, 14);
System.out.println(font)
