java.sql.SQLException: Smart-large-object error.

[ROMANGELOV]

Hi all,
I use trial version of Informix 9.4,
I use Java and this piece of code for store my information:

Connection conn = session.connection();
IfxCblob clob = new IfxCblob(conn, document);

this.tsod_store_date = new Date();

if (lrn_mrn != null) {
if (lrn_mrn.length() == 22) {
this.tsod_lrn = lrn_mrn;
} else {
this.tsod_mrn = lrn_mrn;
}
}

this.setTsod_msg_type(msgType);
this.tsod_document = clob;
this.cnt_sid = cnt_sid;
this.is_pdf = isPDF;
session.save(this);
session is org.hibernate.Session...
But my application work strange...there is a exception with trace like this:
java.sql.SQLException: Smart-large-object error.

and I don't know the reason for this error because, it's throwed when the DB is with a few record, if the DB is empty there isn't this error. Can you help me ?
