You may like to read an interview with Dennis Leung, VP TopLink Development, dating back to January 2003, on TheServerSide: Hard Core Tech Talk with Dennis Leung, VP TopLink Development and perhaps even more the many discussion threads spun from this interview. JDO is discussed at length - and not very positively. There is also a pretty healthy stance from Rod Johnson on "Java-experts" ignoring the strengths of relational databases and database experts in order to "OO and EJB" the world. There is also this MagpieBrain blog which discusses various persistency frameworks. Brian McCallister notes there: "The most common I see used, in order, are: EJB CMP, EJB BMP, Hibernate, OJB, TopLink, Various JDO impls, Cayenne, Cocobase (yes, people use this despite Warren). This is very informal and unscientific, however."

I’m not convinced that JDO is running out of steam, although I certainly think that Hibernate’s popularity has posed some problems for them. Do you have any evidence to back up the claim, or is that just a hunch?
