    Problem getting Object form BLOB

    joda Newbie

      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
