Hi John,
I don't think there is a 1-to-1 relationship between EJBOBjects and bean
instances; this issue is vendor-specific, but I'm sure most server pool and
reuse EJBObjects just like they do bean instances. The reason why
EJBObjects can be pooled and recycled is because they don't contain cli

If you are doing SQL INSERT and do not want to supply a value to a column

John,
I suggest that you embed the primary key into your client object references
(for a CORBA-based server, embed the primary key within the object_key part
of the IIOP profile). You might want to add to that a per-client unique id
to allow multiple clients to have distinct references to the 'sa
How about omitting the column from your insert statement, i.e. instead of:
insert into table (myKey, myColWithDefault) values (123, null)
do:

If you are using CMP you will need to check with BEA whether this is possible.

Kumar,
You should change:
book = (lafpackage.Book)bRef; //Exception occures here
to:
book = (lafpackage.Book)PortableRemoteObject.narrow(bRef, lafpackage.Book);
This is required for portable code, and clearly your container needs
it to be done portably.

You must design your EJB to avoid to load all the images
data in the AS memory.
To do that you can create a RemoteIterator which stream
data on a chunks-per-chunk basis from the database
to the EJB and then to the client.
The Remote Iterator is a stateful (it use a JDBC Statement)
