KODO not reading object as BLOB

Question

I am using Kodo JDO 2.4.3, MS SQL Server 2000, and the pure java driver
com.jnetdirect.jsql.JSQLDriver (JSQLConnect.jar ).
I have a class with a serializable object as member variable. When this
class gets persisted the member object gets stored in database(as BLOB),
but it is not populated while reading it. This object is null when
accessed through its accessor method.
Is there something I am missing? Pls help.

Answer 1

Manoj-
Most of the warnings are expected and can be ignored (and are caused by
the MS JDBC driver inappropriately issuing warnings when they should be
log messages, and a known bug with their ResultSet.close() method).
However, I notice that you are getting the following error:
[Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]Violation of PRIMARY
KEY constraint 'PK__JDO_SEQUENCEX__2D7CBDC4'.
Cannot insert duplicate key in object 'JDO_SEQUENCEX'.Does this mean that anything is working at all for you under the MS
driver, or that your blob test case is completing without errors (and it
is just the case that the blob field is null)?
Also, can you post the .java and .jdo files, so we can take a look to
see if there is anything wrong with your configuration?

I tried with MS's driver too, with same result. Serializable object's data
is not loaded at all, when accessed through its getter method. I do not
see the relevant SELECT statement from KODO in the console.
With MS's driver, we see much more warnings and errors printed on the
console, not sure if they are serious but look scary. Below is the console
printout of the problem, when tried with MS's driver, storing first, and
then retrieving.

Manoj-
First, note that we do not test with the jnetdirect driver (we recommend
using the latest version of MS's own driver, which is free:
http://www.microsoft.com/sql/downloads/default.asp).
However, if you want to proceed with the jnetdirect driver, you
can check to see if this is a storage problem or a retrieval problem:
can you use the server tools to see if the row is ever populated with
the blob at all, or if it is null in the database.
