How do you call a pdf2txt dll from a java program to convert a pdf file to a text file

I am working with a product called pdf2txt from a company called verypdf.com This program allows you to convert pdf files into text files. The software really didn't come with much documentation. From my research I have found that I would need to write a wrapper program to use the dll provided with pdf2txt. Does anyone know how to call a pdf2txt dll from a java program.

Welcome to JavaRanch.

Several possible approaches are mentioned here: http://faq.javaranch.com/java/JavaIntermediateFaq#callingCom. I'd start by looking into JNA.

Thanks, I will look into JNI.
