Flying Saucer and CSS - css

Question

When using flying saucer to convert to xhtml to PDF, I'm getting the following exception:

I was able to view the content of the css file through the link: https ://.../file.css and I have create a keystore and certificate in JBOSS server and made sure ssl.conf is pointing to them (redhat). It seems there is an issue maybe with https, but have no idea how to tackle this. Has anyone experienced this issue before?
Thanks,

It's too late, but someone else may found it useful. Here's how I solved my issue:
Turned on the Logging (Turning on Flying Saucer java.util.logging Output)
System.getProperties().setProperty("xr.util-logging.loggingEnabled", "true");
XRLog.setLoggingEnabled(true);
Read the org.xhtmlrenderer.swing.NaiveUserAgent logs for
public String resolveURI (String uri){
/**/
}
(If you can remote debug it/run JBoss locally - put a breakpoint there and you'll see all the font/resource/css loading)
In my case it turned out the baseURL is wrong for the renderer. You can pass it to renderer while parsing document.
renderer.setDocumentFromString(generatedHtml, getBaseUrl());
And to get the valid baseURL on my env I've used:
"jndi:"+servletContext.getResource("/").getPath()
(turned out you actually can access static files in the deployed war with this "jndi:" prefix.)
