i defined a table including one blob column as follows:
create table contact(
id     number(22) primary key not null,
lastupdated date not null,
lastwriter_id number(22) not null,
contacttype_id number(22) not null,
notice varchar2(2000),
attachment blob,
attachmentname varchar2(255))
tablespace users
storage (initial 2M pctincrease 0)
lob (attachment) store AS (
tablespace users
storage (initial 10M)
enable storage in row
          pctversion 5
          chunk 1
index lob_attachment_idx (tablespace users storage (initial 1M)));
now i fill this table from a java application using hibernate.
small files (for example 2700 chars) are ok, the pass into the attachment column.
larger files dont go there. i receive no errormessage.
