org.hibernate.tool.hbm2x.ExporterExcept when reverse engineering a DB

Description

Hi,

I am trying to use hibernate tools in eclipse to reverse engineer a complex db, and I sometimes get "org.hibernate.tool.hbm2x.ExporterException: Error while processing Entity: persist.eXacto.Left with template pojo/Pojo.ftl" type exceptions.

After much tries, I have been able to track the error down to the following schema: https://smg8.ulb.ac.be/hib/SQLdiag.gif . The sql to create the problematic schema is the following: https://smg8.ulb.ac.be/hib/create_DB.sql .

The stack trace reported by Hibernate tools through the eclipse error log is here: https://smg8.ulb.ac.be/hib/stacktrace.log . The configuration files are here: https://smg8.ulb.ac.be/hib/logback.xml ; https://smg8.ulb.ac.be/hib/hibernate.reveng.xml ; https://smg8.ulb.ac.be/hib/persistence.xml .

I have not been able to log anything else from Hibernate other than the error stacktrace here above, altough I tried to configure logback correctly and enabled sql debugging in persistence.xml. What is missing to enable detailed log output?

Please tell me if you need any other information. I am beginner in Hibernate. Thank you for any help or pointer.
Olivier

applied to hibernatetools core trunk. Added actual test for this at the low levels too.

I just have not had time to incorporate the issue.

Will make sure it gets into the next release.

Thanks once again for the patch and the fast action, and sorry to insist, but how should I update to a version including the patch? (I hope there is a simpler way than recompiling hibernate tools...)

I am using JBoss Tools Development update site in eclipse, and updated to today's version, but that does not help.

The patched file is java/org/hibernate/cfg/reveng/DefaultReverseEngineeringStrategy.java. Indeed there is such a file (in .class form) in hibernate-tools.jar, both in the org.hibernate.eclipse_3.2.4.CR2-R200901280154 and in the org.hibernate.eclipse_3.2.4.CR1-R200812191611 version of the plugin I used before. But both class files are identical, so obviously the today version does not include the patch. Is that intended?

Thank you for any pointer and sorry if it is stupid and simple... I really looked hard and found no doc on that subject.

Thanks for the patch and the workaround (which is however not so useful in my case because the full db is complex and I'd like to use the many-to-many detection when rev. eng. it). Sorry if this is a stupid question, but do you know when will the patched version be available in the eclipse update repository / maven?

patch is attached.

FYI a workaround is to disable many-to-many detection.

Fixed
