If I had to guess, I'd say that there's a mismatch between the column
capitalization that your database is returning and the ones that you're
using in your expressions (e.g., "proj_name" versus "PROJ_NAME"). JSTL is
currently case-sensitive in this regard, although we're actively
considering whether (and how) to make it case insensitive.
One easy way to tell for sure if column-name mismatches are at the root of
your problem is to use 'result.rowsByIndex' instead of 'result.rows' and
then to access column numbers instead of names.

Similar to what Jan said, this sounds just like the tag isn't finding your
bundle. (As Jan said, the name for the parameter/attribute changed.)
