Hi,

I am using Jboss 3.2.2RC4 / CMP with mySQL.
I have an CMP Bean with an CMP field
of type Object (I store images there) and SQL-type LONGBLOB.
I have no Problme storing the image as a byte[]
but when I try to get the Object I get the following
error:

java.sql.SQLException: Unable to load to deserialize result: java.io.StreamCorruptedException: invalid stream header

I'm sure the datebase containes the image (i can see it in mySQL-Front), but I cant get it out....
I have no clue what I am doing wrong, any
help would be appreciated!

Thanks
