Hi Scott, I had the same problem some days ago. It happened because I forgot the -Pxpdf-mediafilter-support when running Maven. As a consequence the ImageIO JARs weren't included and the read() call returned null. Check for the following JARs in [dspace]/lib/ in case they are missing for some reason: jai_core-1.1.2_01.jar jai_imageio-1.0_01.jar Cheers, Àlex ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
