Actually, there's a bug in iText when trying to create an Image using
getInstance( String )!
The method toURL in Image.java starts with the following rows:
public static URL toURL(String filename) throws MalformedURLException {
if (filename.startsWith("file:/") || filename.startsWith("http://";)) {
return new URL(filename);
}
You'll need to add an 'filename.startsWith("https://";)' in the if
statement to support loading images through a secure link. I fixed this
in my servlet by creating my own URL instance and feeding getInstance()
with that instead!
