I've toyed with EJBs for quite a while, all the way back to 1.0. But so far
its been too cumbersome and offered little gain in most environments I've
been working in (e.g. the overhead of remote calls, etc, outweighed the
potential benefits).
Now with the 2.0 spec its gotten to a good place

Nope. MS SQLServer is not case insensitive. You could always tweak

Neither is Oracle. Oracle actually stores all its DB Fields upper case, but
it doesn't matter how you refer to then, meaning select column1 from Table

Hi,
currently I have to decide wich way to go with a new EJB Project.
We need some App-Server independance so we have to decide if we should use
CMP with the EJB2.0 Relationships and QL or BMP with our own SQL-Statements.
Is there any information available when Orion will support EJB2.0
Is there any information available when Orion will support EJB2.0
and EJB QL
My thoughts on CMP vs BMP:
On my project I went with BMP + DAO patterns + business deligates
at the client tier that deligate reads to the much more efficient
DAO's (direct access to the DB) and updates
Does anybody know when we can expect to see the EJB2.0
features like , ejbSelect, local interfaces etc in
Orion ?
Thanks
