Does anyone know if DataNucleus is actually getting JPA certified? Last I checked, it is not a certified JPA provider, correct?

The DataNucleus project doesn't get involved in signing NDAs and condoning of closed source (secretive) programmes. Feedback from our users is that this "certification" is of no value to them, and they don't see what it is testing nor can they influence the make up of that testing. Feedback from them also says that way more importance would be placed on getting an official JPA 2.1 API jar in Maven Central, so the most popular items in the JSR 0338 issue tracker FWIW (not that there's any sign that this will ever be acted on) https://java.net/jira/browse/JPA_SPEC#selectedTab=com.atlassian.jira.plugin.system.project%3Apopularissues-panel

If you are referring to the TCK not being open source, there are good technical reasons for that - namely the risks to compatibility it poses (Sun detailed this problem years ago). That being said, non-profits can get free access to the TCK through the scholarship program. Eclipse was recently granted one: http://www.marketwire.com/press-release/oracle-grants-compatibility-testing-scholarship-to-the-eclipse-foundation-nasdaq-orcl-1788684.htm.

I think it is confusing to state text like "standards-compliant" without actually having passed the TCK. I suggest clarifying the text, with an explanation as to what the actual situation with the product is since "JPA compliant" means something very specific in terms of JCP standards.

Oracle people do get so tiresome at times; we've been through it all before. http://datanucleus.blogspot.co.uk/2010/04/jpa-and-role-of-compliance.html http://datanucleus.blogspot.co.uk/2011/01/jpa-tck-request-and-jpa21.html I strongly suggest that you at least respect other people's opinions with regards to not wishing to use closed source, and not wishing to sign NDAs. I have my views (and I know many others that share them), you have yours, there is no solution. Move on. The DN docs states very clearly the situation http://www.datanucleus.org/development/test/jpa_tck.html

OK, if the relevant folks are already aware of the problem, I am sure they will handle it as they best see fit. Personally, I didn't see any issues with TCK access while getting Resin certified for the Web Profile. BTW, here is a link to the Java EE 7 API Maven coordinates: https://wikis.oracle.com/display/GlassFish/Java+EE+7+Maven+Coordinates . By the looks of it, the EclipseLink team maintains the JPA portion, so any Maven related requests should really go to them, not the JPA spec itself (which has nothing do to with Maven).
