Hi,

I got recently involved in the problem of choosing an O/R mapper (again ...)
* It's for a very large size company ...
* it's for Java
* JDO would therefore be a good idea (pls. don't challenge me for
  this one - I had my portion of the JDO vs. X discussion :-))
* the vendor should not be a shop with 2 mio USD annual turnover, but
  somewhat bigger - open source is not our prime policy.
* the database backend will be IBM DB2
* we did read Bitter EJB and Entity Beans are not our prime target
* session beans would be o.k. - but we feel that CMP is too heavy
* The kind of vendors we would like to buy from are the size of IBM
* the ones we find are more of the very small shop kind ....
* Gartner doesn't help here :-) almost no information

Questions ...
* is TopLink/Oracle offering JDO (seems so) but are they also still
  supporting DB2? I have bad feelings if it comes to that :-)?
* does anybody know abou where TopLink is headed?
  Will, they be fully integrated into the Oracle App server and be consumed
  or will they have some kind of an independant future?
* are there any JDO vendors with some significant turn-over
  Libelis I was told is of the few million turn-over category - what
  about SolarMetric - are they significantly bigger?
  (I'll have a look at Versant/Poet figures myself :-))
* any other suggestions?

Thanks

Wolfgang
