Parsing hbm.xml file error

Hi,

I just downloaded nightly snapshot for Hibernate Tools to see how hbm2java really works. I compiled the source code in eclipse and tried to parse Fligh.hbm.xml file generated by middlegen. But I received following error. Does anyone know why I'm receiving this?

Code:

10 [main] ERROR hbm2java.CodeGenerator  - Error parsing XML: file:/D:/Study/Programming/Java/EclipseProject/hibernate-tool/hbm/airline/Flight.hbm.xml(23)
org.xml.sax.SAXParseException: Attribute "generator-class" is not declared for element "id".

...best guess - you are using the wrong dtd for the hbm.xml...or you are using the right dtd, but have bad xml ;)

...it is a DTD validation error, not anything specific to hbm2java (or at least, it does not look like it)

From the name you are using the standard example so unless you are using the experimental version of the plugin (which does not generate correct xml). Otherwise, I would expect the result to be accurate. The latest is release 2 from Source forge Hibernate downloads. If this is the version you are using then provide the mapping file in question.

Again it seems like I was using old version of Hibernate plugin for Middlegen. What I did was I got Middlegen's source code from its CVS and generated hbm.xml files from the code I compiled in Eclipse. However, the version of hibernate plugin source code in the Middlegen's CVS is very old and not compaible with current version of hibernate. (hibernate.vm file is totally different).

I might post this message to Middlegen's mailing list.

No need to post they already should know. You got the experimental version of the plugin which is very broken. Middlgen CVS Head it is also a broken version of Middlegen and is not being worked on at all. The correct version is Tagged with 'VALUEOBJECT_REFACTORING_BRANCH'. This branch is the base for the version 3.0 effort.

The correct version is Tagged ith 'VALUEOBJECT_REFACTORING_BRANCH'

Does everyone have the access to the branch? I get the following error

Code:

cvs [server aborted]: "tag" requires write access to the repository
Error, CVS operation failed

I'm sorry that my question is the way too off topic and not relevent to hibernate at all. This time, I might really need to post my question to middlegen mailing list.... Thank you for your advise, David!

It is OK to continue it here or start a new thread. I spend most of my time here rather than on the Middlegen list. The CVS should work fine. Sourceforge has been giving all readonly CVS users hell lately and I would expect that would be the issue. The release 2 download was the latest version and I have not released any further enhancements as yet.
