Emmanuel Bernard commented on ANN-678:
--------------------------------------

you forgot to add hibernate-commons-annotations.jar in the classpath next to hibernate-annotations.jar
Some components of Hibernate annotations have be factored out.

>          Components: binder
>    Affects Versions: 3.2.1
>         Environment: Annotations 3.2.1.ga , Hibernate 3.2.3.ga, entity-manager 3.2.1.ga. JDK 1.5, JBoss 4.2.0, Ubuntu, MySQL 5, SVN, Maven 2

> As former posts of this same problem, when we use bidirectional OneToOne relations
> We get NullPointerException.
> It is quite an odd problem since this problem is not consistent. 
> I built my sources and had this problem consistently, then when I changed the name of the folder I checked out the code to,
> built again and then deployed on JBoss, it worked OK. Meaning the mappedBy text and the rest of the annotation setup is ok.
> I saw this issue is supposed to be resolved in 3.3.1 BUT Jboss 4.2 does not work with 3.3.1 due to backward incompatibility issues.
> So a fix for 3.2.1 is necessary.
> I can past the stack trace but it is exactly the same to former posts on this same issue.
