Discalimer: I know nothing about DB2. However, I do know that in MySQL that there are configuration settings that govern how large of a BLOB MySQL will handle. You should check the DB2 docs about how BLOBs are handled and regarding pertinent config settings. Also read the docs on the JDBC drivers to see if they have any BLOB-related settings or quirks. Sorry I could not be of more help. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4257892#...
