pdf to txt

I found this library that work in B4A made by @MarcoRome https://www.b4x.com/android/forum/threads/pdf-to-text.81449/ I would like to know if works in B4J too, because i test it and no results. Thanks.

I would like to extract text raw from a PFD. I have looked briefly at the jPDFjet library but it seems like a heavyweight option aimed primarily at the finer points of PDF authoring rather than engineering in the opposite direction. Is there a simpler option I have missed? Any suggestions?
