only call response.getWriter() when we are about to send text/xml to the client, otherwise we end of calling both getWriter() and getOutputStream() - resulting in an illegal state.

uncomment the other test cases and make sure we do the clean up when the tests are complete (delete the uploaded documents)

copy, compile, and run the test classes using UTF-8 encoding since they contain special characters

use detected XML encoding when reading/writing files
use UTF-8 as default when performing queries in the DB (assume DB is using UTF-8)
remove as many PrintWriters (uses system default character encoding only) as possible and construct OutputStreamWriters where explicit encoding can be given....
