This gave me a NullPointerException, because the Driver only sets the StreamRenderer on the FOTreeBuilder when calling one of the two render() methods. (Which is not necesarry when using the ContentHandler instead.) Therefore I used the following hack to make things work:
StreamRenderer streamRenderer = new StreamRenderer(new FileOutputStream("c:\\baz.pdf"), driver.getRenderer());
((FOTreeBuilder)handler).setStreamRenderer(streamRenderer);
But I still get a NullPointerException. I cannot, however, see where it is thrown, as Xalan eats all original exceptions.
If serialize the excact same series of SAX events into a file and run FOP as a command-line program on this file - everything works dandy.
So what this boils down to is: I can get FOP to process the XML as long as it comes from an XMLReader (Xerces), but it won't process the excact same XML when it comes from Xalan.
I suspect that the problem could be namespace-related. But what can I do differently with the Driver/FOTreeBuilder?
