Sorry folks, I hadn't seen this thread in awhile and no one PM'd me about the issues...
The zip comes with compiled Java .class files, but they are compiled for Java 5 and will not work on a prior Java version such as 1.4.2.
The code works with PDFBox 7.1 or 7.2. I haven't tried it with 7.3.
I'm bundling up the xpp3 and jpedal into a zip and attaching them.
I'll have a look at the Python code and see what kind of command line some folks like. It should be possible to remove the dependency upon Python.
