PERSISTENCE LOB WITH JPA

Question

Hi, Folks. I have this problem using JBOSS, EJB3 and MSSQL Express . i'm trying to persist an entity with an Blob attribute which was converted into a byte[], apparently it create the entity perfectly, no error was logged at jboss's console. but when i check into database the column is null. i already checked the Object to byte[] method and it is fine. i tried assigning Image and varbinary(Max) data type to this column. so i really don't know what it happening, why the column is not inserted into database.

thanks a lot.

@javax.persistence.Lob
@javax.persistence.Column(name = "BUSINESS_OBJECT", insertable = true, updatable = true)
public byte[] getBusinessObject() { return businessObject; }
