Subject Re: generating data url external-graphic in PDF

```Yes, I am able to verify that the property is set
before and after the PDF generation
(System.getProperty("java.protocol.handler.pkgs") =
"org.apache.fop.util.protocols").

What do you mean by registering the protocol handler?
with the two classes in my Java Source (I am using
WebSphere) and the classes get generated in my
WEB-INF/classes.  I overwrote another FOP class the
same way (as a test) and my version definitely gets
executed.  Interesting thought though, looking at the
FOP source and the classes from the JAR file, I cannot
see the org.apache.fop.util package or classes.
