ODMG just states that any persistence capable object should be allowed as key and value. But ODMG does not specify that *all* primitive types (and STrings) must be handled as persistence capable entities! (That's one of the things that is changed in JDO!) OJB is taken advantage of this gap in the spec and frankly tells you "We are happy to store *references* to everything in a DMap, but the user is responsible to store the *everything*" ;-) > Or is it a feature / > limitation of the current implementation? > I have assumed that I can simply use a string as the map-key.

It's not a problem to implement such a map. We could easiliy provide utility classes and the respective tables and mappings. But we don't do so as a lot of user are already moarning about all the tables the ODMG implementation requires. cheers, Thomas > > Thanks, > > --Tim > > -----Original Message----- > From: Mahler Thomas [mailto:[EMAIL PROTECTED] > Sent: dinsdag 17 juni 2003 15:20 > To: 'OJB Users List' > Subject: RE: DMapImpl > > > DMapImpl keys must be real entities! that is there must be a > table to store > them and a class-descriptor provided. > > > -----Original Message----- > > From: Leeuw van der, Tim [mailto:[EMAIL PROTECTED] > > Sent: Tuesday, June 17, 2003 3:15 PM > > To: '[EMAIL PROTECTED]' > > Cc: 'OJB Users List' > > Subject: RE: DMapImpl > > > > > > Hi Cedric, > > > > Did you ever get an answer to this question?
