|IMHO making Xid an interface is a _big_ mistake:
|It should have been a final class.
nuff said.
|There is _never_ more or less information in an
|Xid, or interoperability with OTS/JTS and X/Open
|DTP would be void.
|
|I don't know why Oracle made a version of their
|JDBC driver dependent on a particular Xid
|implementation, and I see absolutely _no_ reason
|why anyone would want to do that.
well, think about it... come on...
:)
right to break interoperability.
Oracle REALLY doesn't want a succesful EJB world because it means less
visibility of the DB tools.
It is still the future though.
|And I think that Oracle have learned an important
|lesson from their mistake: Unlike JBoss, one of
|the major J2EE vendors (I don't remember if it
|was IBM or BEA) said: "We do NOT want to support
|this; that driver will _never_ work in our
|application server".
well, you got it all reverse. Oracle ****I*M*H*O**** is interested in
killing the EJB market, they have NO interest in seeing a BEA own the
middleware tool market, they want it and the best way is to make sure you
need to go with all their stuff to make it work. Classic.
In fact (again imho) the recent Orion move is an effort to KILL the market
AFAP, god!!!! we were supposed to do that all by ourselves!!!! and now
Oracle is making sure they throw some oil on the fire... did you feel this
acceleration??
it's an ugly war, the webOS is at stake, BEA was getting fat and lazy (if
not arrogant), IBM, well IBM is IBM, SUN is a bunch of monkeys, ORACLE
want's to kill them all in DB middleware world... ***we***, you and me, will
still own this market if you believe.....
Don't loose focus on the "2-tier/3tier/ntier" middle age discussions going
on everywhere, this is the time, stay focused, the webOS with CMP is the way
of the future, stay low, when the monkeys are done jumping up and down we
will have the black monolyth.
love,
marcf
