Hello,
I'm running DSpace 1.5.2 XMLUI on a Linux system, and I've been trying to
install the XPDF tools for PDF thumbnails, following the recommendation of a
user on this list. I followed the instructions to install the tools in the
1.5.2 documentation and believe I've successfully installed the jai_imageio jar
and set the configuration correctly. But when I try to run the filter-media
command, I'm getting errors with pdfoppm.
The documentation mentions that a POM in the dspace-api module needs to be
edited, but it doesn't specify which POM, and what element needs to be added.
I've included a sample of the errors below. Thanks for any help you can
provide.
Error:

I have verified that the XPDF tools, including pdftoppm, are in the /usr/bin
directory.
Cheers,
Eric
