[CDO/Hibernate] Exporting Hibernate Mapping [message #953619]

Mon, 22 October 2012 07:52

Eclipse User

Hello

I am currently playing with possible workflows to handle model evolution. I wanted to try something that Tom suggested in another post: Export the hibernate mapping and convert this to a DDL file which can be used to determine deltas to the schema.

I am having difficulties with step 1: Exporting the hibernate mapping.

I am trying to do this with the OSGi command "hibernate mapping <repo name> <file name>". The file itself is exported, but my teneo-properties (i.e. teneo.mapping.inheritance and teneo.mapping.persistence_xml) specified in cdo-server.xml are not used. So the file doesn't realy represent the current status.

Is there another way to export the hibernate mapping? Or is there a way to configure the OSGi command?

Greetings
Christoph

I am not sure how the cdo repository properties should be added to the hibernate mapping file.

Though, that is an interesting approach to diff the hbm files and generate ddl to migrate the database to a newer model version.
I have found the following project which seems to be quite interesting and does the hbm diffs:

Would be great if you would share your results!

Hi Christoph,
I entered a bugzilla and pushed a change for this a few minutes back:
http://git.eclipse.org/c/cdo/cdo.git/commit/?id=a65d08e000e88a26482e925623eec4c968c8a07c

Will be in the next 4.2 build.
http://www.eclipse.org/cdo/downloads/

Can you let me know if this solves your issue?

gr. Martin

@Martin: Thanks for the quick support! Your fix resolves the issue. Could you please merge this into the 4.1 maintenance stream? (I did a cherry-pick of the commit and it worked fine.)

@Erdal: Thanks for the tip Smile

. I'll look into it.
