Hi gang,

I just looked in DTD ( 2.0, on hibernate org ) and discovered that
there are new attributes for <property> ( index & formula )

Yet it's still 2.0, no version changes.
So I updated xdoclet-2 plugin for hibernate to support this.
And I was immediately bombed by hibernate in my unit test
( I'm using now 2.1.4 in production ) - xml parser said it does not like this attribute...


What is your strategy to deal with changes in dtd ?

regards,

Pretty much straightforward: The DTD for the release is packaged inside the release, in hibernate2.jar. This is the latest and working DTD, in your case, in the Hibernate 2.1.6 distribution.

The DTDs you can find on http://hibernate.sourceforge.net/ (there are none on hibernate.org) are also the latest released versions for the stable (2.0/2.1) and testing (3.0) branch. Sometimes we have a few days lag after a new release, but it shouldn't matter: Resolvers have to read the DTD from the hibernate2.jar file, anything else would be broken.

Hmm, then I'd have to care for hibernate version in xdoclet-plugin
( or at least to document what is supported and what is not )

But that version is still 2.0 confuses me...

BTW, do you plan to add index support for collection elements (
primitives ) and keys?

I don't know what the "xdoclet plugin" is, certainly not a maintained and official part of Hibernate. There is nothing confusing about the 2.0 mapping DTD, its valid for Hibernate 2.0 and 2.1 though.

it's certainly not maintained by hibernate. it's plugin for xdoclet-2
maintained by me and couple of others.

and you may imagine, that it has to follow hibernate DTD
somehovw, and it's difficult if it changes without version change...

So, just take the latest version of the DTD from the distributed package, whenever there is a new release.

He means the Hibernate XDoclet module. He's one of the maintainers.
