Subject: FOP 0.93: Cannot load fonts/NullPointerException
|
I’m using the DocBook 1.72 XSL stylesheets with FOP 0.93. I followed the Apache FOP instructions for regenerating font metrics files, and I updated the FOP configuration file to the new format. When I run FOP, I get the following exception.
SEVERE: Exception java.lang.RuntimeException: Cannot load font: failed to create Source from metrics file SY______.xml
It didn’t seem to be loading any of the fonts. The <font-base> in the configuration file was correct, so I don’t know why it couldn’t load the files. I decided to update the configuration file to use relative URLs based on the <base>. When I ran FOP again, I got a NullPointerException:

Any idea what could be wrong?
