We have column type Clob in db2 database. Since we can't handle java.sql.Clob on java side, I changed property type from Clob to String in hibernate mapping file and also in POJO from Clob to String. Still in db2 column type is Clob. After this modification I successfully inserted relatively small size string into database. However when I try to insert large string I get following exception.

Can anyone advise how do I handle this? keeping Clob in db2 and String in hibernate side. or is there any other way to achieve this? or is there a way to use Clob on java side? insert text in Clob from hibernate , how?

I forgot to paste half of the exception :
