Thanks Tilman,
Yes. I created the project from scratch and do not need to use logging at this
pointI found a tutorial on-line It has non-copyrighted sample scripts that one
can copy and use.
I am just trying to use the PDDocument.textStripper as a starting point.
Since I emailed the group yesterday, I managed to find some slf4j jar file(s)
and imported them to the project
Now that the slf4j files are imported, there appears to be some sort of new
dependency that seems cryptic to me.
Today, I will try to back out some of the jars I imported as they do not seem
necessary. And then trace through my project for other clues.
Thanks for your response.

Hi,
PDFBox does not require slf4j, so the import isn't needed unless you use
it yourself. Maybe something else uses it. The exception
NoClassDefFoundError means that slf4j jar file(s) is missing in your
class path. So you need to check your project whether it is there or not.
Did you create your project from scratch or did you find something on
the web?
