Re: [hibernate-dev] HBM migration suggestions
hibernate tools can do it for the basic cases - but it haven't been updated in a long while, but you can customise the templates if you find issues. /max > Hi guys, > We have 200-ish hbm files we would like to convert to annotated > classes.

Re: [hibernate-dev] HBM migration suggestions
I remember needing something like that and did it by having the legacy app create the schema in the RDBMs, then use reverse engineering to pojos. This was during the "Seam 2 era" so quite some time ago.. not sure how tools evolved since then. You'll need some manual tuning during both steps of course, but since I could tune & extend both the naming strategies (via code extensions) and the template files we got a quite complex application (600+ entities) converted in a couple of days. AFAIR my best learner lesson was to be ready to repeat it all (script it) multiple times, to prefer tune the templates and naming strategies iteratively over fixing things by hand.

Re: [hibernate-dev] HBM migration suggestions
Do you have a tool to convert from orm.xml to annotations? The reason I ask is that we are pretty far along in the development of a hbm.xml -> orm.xml tool, with the caveat that the orm.xml is an "extended" form of the JPA orm.xml weaving in Hibernate-specifics. So it would depend on whether any hbm-specific features are used (property-ref being the biggest problem). That tool with be completed as part of 7.0, but like I said it is already pretty far along.

[hibernate-dev] Hibernate OGM double release!
Good news! We released Hibernate OGM 5.1 Alpha1 and 5.0.2 Final! Hibernate OGM 5.0.2.Final now supports MongoDB 3.2 and it’s still backward compatible with Hibernate OGM 5.0.1.Final. Hibernate OGM 5.1.0.Alpha1 brings support for Neo4 in remote mode. We also started to re-work the way Hibernate OGM groups operations before running them; this reduce the number of calls and commands to execute on the datastore, leading to better performance. You can find more about these releases and how to get them in the blog post: http://in.relation.to/2016/10/10/hibernate-ogm-5-1-alpha-and-5-0-2-released/ Thanks, Davide ___ hibernate-dev mailing list hibernate-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/hibernate-dev

That was doing it wrong then ;) hibernate tools have since day one been able to read any hibernate config and generate another config from it. Thus generating to the db first would be unnecessary. The tools haven't moved much since then though :) > You'll need some manual tuning during both steps of course, but since > I could tune & extend both the naming strategies (via code extensions) > and the template files we got a quite complex application (600+ > entities) converted in a couple of days.
