insert over one CLOB column error ORA-01461

inseHi guys

I'm getting this error message when I'm doing a inert thrh ojdbc 6 driver

org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [INSERT INTO TSYUSER.BBG_DETALLE_ENVIOS (ID_DETALLE_ENVIO,PORTAFOLIO,TIPO_MOV,SECURITY,FECHA_OPERACION,DET_ERROR,COMENTARIO,FEC_ENVIO,HORA_ENVIO,INFO_ENVIO,RESULTADO_ENVIO,FEC_ACT,HORA_ACT,TRADER,TICKET_NUMBER) values (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)]; SQL state [72000]; error code [1461]; ORA-01461:

Note the column its CLOB; it shouldn't have any issue to do insert bigger than 4K

Any idea on where it could be the issue
