Hi Fuhwei,
In the latest proposal there are actually two plug-in points that can
be configured:
- SDO Implementation
This is for setting up SDO for a particular environment. WebLogic and
WebSphere would each include an implementation of this, so that
instances of HelperContextFactory behaved correctly inside their
environments. An SDO Implementation could also be created for OSGi
environments like Eclipse Equinox so that SDO behaved correctly there
as well. The configuration for this aspect needs to be improved.
- HelperContextFactory
This is the other plug-in point where different vendors can
provide access to their own HelperContexts. This would allow multiple
SDO implementations to be available in the same SDO environment.

Can we change the following statement
in Implementation.java from
static final String PROPERTY_NAME =
"commonj.sdo.helper.HelperContextFactory";
to something like
static final String SDO_IMPL_NAME =
"commonj.sdo.impl.Implementation";
because the value of the system property
is the user specified Java class for the SDO implementation.
Thanks.

Hello All,
I have added the next revision of the SDO 3 API that includes both
HelperContext creation and standardized serialization.
-Blaise
-- Mr. Blaise Doughan
The document revision named HelperContext Creation - Version 3
(HelperContextCreation-v3.zip) has been submitted by Mr. Blaise Doughan
to
the OASIS Service Data Objects (SDO) TC document repository. This
document
is revision #2 of HelperContextCreation.zip.
Document Description:
API Now Includes:
- HelperContext now has an optional identifier property
- A standard implementation of Resolvable that makes use of the
HelperContext identifier property so that de-serialization can occur
outside of the default HelperContext. Also DataObjects serialized
by one
vendor can be deserialized by another vendor.
- The ImplementationResolver has been renamed Implementation and is
used
to
configure SDO for different environments such as Java SE, application
servers, OSGi, etc.
- There is now one default HelperContext available from SDO instead of
one
per HelperContextFactory.
- HelperContextFactory is now an interface.
- Type how has a HelperContext property.
