I'm not able to save a blob field in MS SQL database.

EJB-signature:

/**
* Returns the wob
*
* @return the wob
* @ejb.interface-method view-type="local"
* @ejb.persistent-field
* @ejb.persistence column-name="WOB"
*/
public abstract byte[] getWob();
/**
* Sets the wob
*
* @param wob
* the new wob value
* @ejb.interface-method view-type="local"
*/
public abstract void setWob(byte[] wob);

When the ejb is persisted i get the following error from the container:
------------------------
15:46:52,046 ERROR [Wob] Could not create entity
java.sql.SQLException: [DETROIT]String or binary data would be truncated.

Any help is appreciated
