Hi,
I'd like to store files in he database (SQL-Server). The File data itself is
stored in a array byte[]. The entity attribute is an Object. The database
column type is image.
I have no problem with storing the data. But when reading the entity data from
the database I get the following exception
2004-12-08 14:59:27,453 ERROR [org.jboss.ejb.plugins.LogInterceptor]

What JDBC_TYPE do I have to configure in jbosscmp_jdbc.xml for the column. I
already tryed BLOB, but this type wasnt supported by the driver.
