Re: [Dspace-tech] Filtering errors with XPDF Tools

[Larry Stone]

These errors imply that the JVM cannot access the executable file. Since the file exists, make sure the user under whose UID the JVM is running has read and execute access to the file /usr/bin/pdftoppm (as well as the /usr and /usr/bin directories, although those are usually world-rx). Better yet, use "su" or "sudo" to assume the UID under which the JVM is running and make sure you can actually run that command.

Java IOExceptions have a way of conflating all file-access errors to "no such file or directory", even when there's e.g. a permission problem, which makes it more of a challenge to discover what is really wrong.
