Subject fox:external-document problems
Date Sun, 25 Nov 2012 23:32:46 GMT
Hello,

I am trying to use fox:external-document to include pdf files using FOP 1.1.

I am doing this embedded, but have reproduced the problems in a stand-alone test case.

The embedded problems appear on Apple Java 1.6.0_37 64 bit and Oracle Java 1.6.0_34 on Windows
64.  The stand-alone test case was only run on the Apple Java (listed above).


The first problem was previously mentioned on the mailing list: The fop-pdf-images JAR being
required.  If this is required, it should be included or documented clear as day (especially
on the extensions.html documentation page for fox:external-document).


After including all four .jars from the fop-pdf-images download, I get the following exception:

Exception in thread "main" java.lang.VerifyError: (class: org/apache/fop/render/pdf/pdfbox/PDFBoxAdapter,
method: cloneForNewDocument signature: (Ljava/lang/Object;Ljava/lang/Object;Ljava/util/Collection;)Ljava/lang/Object;)

Is there anything I can do to make this work?

Thank you,

Jonathan
