Hi,

is it possible to have a persistent field of type InputStream mapped to a
CLOB database column?

Kind regards,
Frank

Minor correction: A BLOB column, of course!

Not really,
You should be able to map a java.sql.Blob as an attribute type, and
get a stream for it. However be careful in doing so, as a Blob requires a
live connection, and cannot be detached. If the Blob is too big to be
read, you may consider dealing with it directly through JDBC or a native
query, not mapping it to your object model.
