[Dspace-tech] Media Filters not generating thumbnails

[Thomas A McGee]

From the command line I get this:
# ./filter-media -vi 123456789/191

Which somehow fails to clarify things for me. What am I missing?

Looks like you might be running the Media Filter with the GCJ version of
Java. Have you tried using a JDK from Sun? They're available here:
http://java.sun.com/javase/downloads/index.jsp

Also, you seem to be running gcj with the Java version set to 1.4.2.
StringBuilder (the class it's complaining about being unable to find)
is new in Java 1.5.
