We upgraded ORACLE to 11g and so I switched to the 11g driver. But
now we started getting these exceptions:

I suspect it is related to BLOB fields because it happens right
after EOF issues SQL to insert into a table with a BLOB field. The
SQL looks something like this:
INSERT INTO MIME_CONTENT(DEFAULT_DOWNLOAD_FILE_NAME, MIME_TYPE,
CREATION_DATE, MIME_CONTENT, MIME_CONTENT_ID) VALUES (?, ?, ?,
EMPTY_BLOB(), ?)" withBindings:
1:"BasicAdHocReport.csv"(defaultDownloadFileName), 2:"text/comma-
separated-values"(mimeType), 3:2010-05-11 11:17:00(creationDate),
4:496737(mimeContentID)
SELECT t0.MIME_CONTENT FROM MIME_CONTENT t0 WHERE t0.MIME_CONTENT_ID
= ? FOR UPDATE" withBindings: 1:496737(mimeContentID)
SELECT ... FOR UPDATE usually means that WO has gotten totally
confused. It should probably be doing something like
UPDATE MIME_CONTENT SET MIME_CONTENT = .... where MIME_CONTENT_ID =
496737
See http://www.google.ca/search?q=SELECT+%22FOR+UPDATE%22+webobjects&;
Often this indicates a difference between your prototypes and the
name / case of the data type that the JDBC driver is returning.

Switching to the old driver makes the exception go away. Any wild
guess if this is an EOF problem or a driver problem?
For reference, the version of the oracle jdbc driver is 11.2.0.1.0.
Thanks for any help,
Ricardo
