This is not an jboss problem but an informix config problem. To store blobs in informix you'll have to define on table creation in which dbspace the blob should be placed. If not giving the info, a config parameter will be used (SBSPACENAME). I prefer to use byte instead of blob. Data for byte is stored in the dbspace where the table/database lives.
