Hibernate mapping resource path in Maven

[Andy Buckley]

Hi,

I just started converting a Java project using Hibernate (www.hibernate.org) to
build with Maven rather than Ant. While I was able to get log4j logging working
again by placing my log4j.properties file in src/main/resources, and putting
hibernate.cfg.xml in the same place does result in it getting picked up by
Hibernate at runtime, I can't seem to get the mapping resource entries correct.

My directory structure is now

src/main
\ resources
| \ hibernate.cfg.xml
|
\ java/cedar/hepdata/model
\ Author.hbm.xml
\ Axis.hbm.xml
\ etc.

and in hibernate.cfg.xml, I've got mapping entries like this:

<mapping resource="src/main/java/cedar/hepdata/model/Author.hbm.xml"/>

which result in errors like

Running cedar.hepdata.AppTest
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.109 sec
Running cedar.hepdata.test.HDOMTest
Initial SessionFactory creation failed: org.hibernate.MappingNotFoundException:
resource: src/main/java/cedar/hepdata/model/Author.hbm.xml not found

I've also tried resource="/src/...", resource="../src/..." and a bunch of
others (even absolute paths, which are useless from a portability point of
view) and none seem to work. Any suggestions? I suspect that the
hibernate.cfg.xml file is getting copied into the target/{,test-}classes
directories and the *.hbm.xml files aren't: should the *.hbm.xml files also be
located in src/main/resources/ to make this work?

Please help!

Andy


PS. Sorry if this is a recurring question: The only mention on the mailing list
archives that I've seen about getting Hibernate working was using mappings like
<mapping class="cedar.hepdata.model.Author" />
but these seem to require Hibernate Annotations and I'm not (yet) using them.
The Hibernate doc/FAQ pages aren't much help either, since they only seem to be
referring to Maven 1.x.

Hello,
yes you should make sure that your hibernate files end up in the resources
directory of your src/java

after that there isno need to put absolute path for your classes, you can
just puit

cedar/hepdata/Author.hbm.xml

and that should work..

1. Put your HBM files into resources, not into java. You should have
src/main/resource/cedar/hepdata/mode/Autor.hbm.xml etc.

2. Use

<mapping resource="cedar/hepdata/model/Author.hbm.xml"/>

Bye.

Fantastic, thanks. The whole tree seems not to be needed, so just making e.g.
src/main/resource/hbm/Author.hbm.xml and pointing the config file at those
seems to work nicely, without having a chain of empty directories for no
particular reason.

Thank you!
