I've been working with the Oracle 9i JDBC driver and a Blob column. 
With both the UserType and a blob column mapping, I receive a "fetch out
of sequence" exception:
    java.sql.SQLException: ORA-01002: fetch out of sequence

The driver version is 9.2.0.4.0.

When I debug through the UserType above, I only see the sqlTypes and
returnedClass methods being invoked.  Neither the set nor the get are used.

Suggestions?
