Ok, thanks for that, i'm going to check it out.

SDO 1 had lots of implementation dependent APIs, that have been replaced
by standard APIs in SDO 2, so moving from SDO 1 to 2 requires some porting
effort.
You should ask questions about the SDO 1 implementation in IBM RAD 6 on
the EMF newsgroup at Eclipse: news://news.eclipse.org/eclipse.tools.emf

Hi.
Thanks for your answer. So, from what i understand, the version of SDO
i'm using with IBM RAD 6 is that version 1 that is now deprecated? Is
it possible to substitute that IBM version with the current Tuscany
version?
Other thing, is it OK if i ask questions directly related to the IBM
RAD SDO version in this mailing list? Do you know another place, since
IBM thinks that that is not necessary? (

Thanks for your help.

SDO is a specification developed by an industry consortium (OSOA). The
current version of the specification is 2.1 and can be found at
http://osoa.org.
Several companies have implementations of SDO in their products
including:
BEA, IBM, Oracle, SAP, RogueWave, XCalia. IBM's implementation of SDO
version 1 was done at Eclipse, but that project has since been
deprecated
and moved to Apache (Tuscany). Tuscany is currently implementing SDO
2.1.
There is also an Oracle implementation of SDO that was recently
proposed
for Eclipse (the EclipseLink project). It will also be SDO 2.1, but
with
different features and performance characteristics than Tuscany.
In terms of standardization, SDO for Java is going to be standardized
via
the JCP (JSR 235). Other languages are moving to OASIS.

Can someone please enlight me about these SDO things?
I've worked in a project a year ago where i used IBM RAD with JSF
and
SDO Relational Records and Relational Record Lists. At that time i
searched the web for material and found almost nothing valuable, but
i
did got the impression that SDO was a proprietary technology that
IBM and Oracle and a few other minor players decided to implement
without the approval of the JCP/Sun and so it was not part of J2EE.
I did found the technology to be very interesting, but due to the
lack
of support and information (among other factors) the work did not
went
well and was interrupted in the middle.
Now, one year after, i suggested again the use of IBM RAD with JSF
and
SDO in a shop that works almost exclusively with IBM technologies.
Despite my bad experience with it. But i found that the information
and support still doesn't practically exist.
However, now i found references to SDO not only with IBM and Oracle,
but also in relation to some other vendors, PHP, and more confusing
with Eclipse and Apache... Oh, and OSOA too..
So my question is, is all these SDO the same thing? Are IBM and
Oracle
and Eclipse and Apache developing the same thing in different ways?
Did they all centralized the development in Apache? If so, IBM RAD
have older versions of SDO or their own implementation?
I think it's all too confusing...
