Hello, I have build a prototype applicition using an evalution-version of a commercial JDO application. However, we'll get a commercial deployment much sooner than anticipated, there will be more developers than just me, and it seems better for us to use open-source products only.
I get the impression that OBJ is most suited for our needs but I'm not sure yet how to switch. - How suitable is OBJ-JDO for commercial deployement, given it's dependancy on the sun-ri? - Using OBJ-JDO will give me the fastest transition-path, switching to OJB-ODMG API can happen a bit slower. However, where can I find documentation on the OBJ vender-extensions for the JDO metadata? - Is there any schema-generator for OJB? Or does OJB always map between existing schema and existing objects? (For me it's better if the implementation handles schema-generation!) - How does OJB handle ordering of data in java.util.Lists? Is the order in the list maintained upon loading from DB? (The various JDO implementations which I tried can maintain this order using an extra column in the table linking the sides of the m:n relationship). I need an easy way to maintain order of elements in a java.util.List field. - I'm currently using MySQL database, but will probably be using hsqldb in future because it's easier to set up on different systems when we don't have to share data yet. I think these are my most urgent questions for the moment. I'd appreciate any assistence.
