Hi Courtney,
Yes, I think I have found the problem, just yesterday.
Originally, I installed the Java Advanced Imaging (JAI) I/O tools and Imaging
API to our current jre at the time.
We run RHEL 5 and the auto (minor) updates to the jre did not bring across the
JAI installed libs. I'll be testing if this is the problem within the next
month but I'm pretty sure it is. I'll post back to the list with results. I
noticed that there is another way to install the JAI based on classpath rather
than directly into the jre - this may be the way to go to avoid future java
updates wiping out your setup.
Hope this helps.
Kind regards
Gary

Subject: Re: [Dspace-tech] Media Filter for TIFFs - NullPointer Exception
Did you ever find a solution to this? I'm experiencing the same
problem, though I know it worked last time I imported TIFF images into
the repo (a year ago).
