I decided to try out the new 3.2.0beta9a version of Hibernate Tools and to try out the hbm2doc with the GraphViz dependency. I am using ANT to execute the tool. When I try to generate the documentation with dot.executable defined to activate the GraphViz diagrams, I get the following error:
Code:

Anybody have any ideas on how to proceed?

OK, I will try 3.2.3 (or whatever it is the latest JBoss is on) at work tomorrow. The versioning has me a little confused however, why are we still on 3.2.0BetaX when they aren't compatible with 3.2.0?

it is compatible. you just showed an error that could/should only occur on 3.1.x

Hmm, that is strange. I tried it with 3.2.3.GA and 3.2.4.sp1 and got the same results. Perhaps something with my ANT configuration is causing me to use an older version - do you know of a way to test that? Is there an ANT task for "which"? Well, that's a little off-topic. I will investigate further.

OK, I tracked down the <whichresource> task in ANT and I am definitely using the latest:
Code:
schema-doc:
     [echo] jar:file:/P:/Engineering/thirdparty/hibernate/hibernate-3.2.4.sp1/hibernate3.jar!/org/hibernate/mapping/DependantValue.class


Looking at the source the problem seems to be in the HibernateTool. Cfg2HbmTool.getHibernateTypeName() uses a EntityNameFromValueVisitor, which does not override DefaultValueVisitor.accept(DependantValue) which throws an exception.

OK, I created an issue (http://opensource.atlassian.com/project ... se/HBX-953). I'm not really well-versed in Hibernate however to the point where I could narrow this down to a simple test case. Maybe you can point me in the right direction, what type of mapping would result in the use of a DependantValue?

any association as far as i remember. Possibly one-to-one's.

Try to just take one class at a time and see when the issue occur.

I was able to reduce the problem to two classes with a relationship. I attached the mapping to the JIRA ticket and will include it below as well for the curious (also as a sanity check so you can tell me if I am doing something stupid).
Code:
<hibernate-mapping>
    <class name="Foo" table="foo">
        <id name="id" type="java.lang.Integer" unsaved-value="null" >
            <column name="foo_id" sql-type="int" not-null="true" />
            <generator class="native"/>
        </id>
        <list name="bars" table="bar" lazy="false" cascade="all">
              <key column="foo_id" not-null="true"/>
              <list-index column="ordering" />
              <one-to-many class="Bar" />
        </list>
    </class>
    <class name="Bar" table="bar">
        <id name="id" type="java.lang.Integer" unsaved-value="null" >
            <column name="bar_id" sql-type="int" not-null="true" />
            <generator class="native"/>
        </id>
    </class>
</hibernate-mapping>
