I installed java-6-sun jdk and made it the default, but I am still getting the
error with the index, though it now references the sunJDK instead of the
OpenJDK. However, when I run a list of open files, I see several files opened
by jsvc (with dspace as the user) that are from the openjdk library. I don't
understand why it would still be using those .jar and .so files if the sunjdk
is the default.

Hi Joshua,
The error message below suggests that you are running the openjdk. Instead,
try installing the official Sun JDK:

This will hopefully help.
