Hibernate configuration using "mappingDirectoryLocations"

[dirtyhenry]

Hi everyone.

My Hibernate configuration was previously made by entering all my *.hbm.xml in a "mappingResources" and it worked perfectly well.

Because of maintenance problems, i've decided to switch to the "mappingDirectoryLocations" attribute and configure Hibernate that way :

    <property name="mappingDirectoryLocations">
      <list>
        <value>classpath:/org/myspace/modele/configuration</value>
        ...
      </list>
    </property>

But it doesn't work. I get the following exception :

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContextHibernate.xml]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Mapping directory location [class path resource [org/myspace/modele/configuration]] does not denote a directory
java.lang.IllegalArgumentException: Mapping directory location [class path resource [org/myspace/modele/configuration]] does not denote a directory
	at org.springframework.orm.hibernate3.LocalSessionFactoryBean.afterPropertiesSet(LocalSessionFactoryBean.java:678)

Note that if I change the classpath name to a name that doesn't exist, I get - luckily - a different exception (FileNotFoundException).

Is thy my IDE that imply that problem ? Has anyone experienced such difficulties ? (i'm using Eclipse with Maven2)

Thanks for your responses.

As my thread is the only one which has remained answerless since yesterday.
So i give him another shot cause i still haven't solved my problem.

I have a similar problem. I have two application context files that define the dataSource and sessionFactory beans; one file for test and one for production. The production one (prod-datasource.xml, which works fine) has this:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
  <!-- setting production Hibernate properties here, blah, blah -->
  <property name="mappingDirectoryLocations"
    value="classpath:au/com/bisinfo/cmgr/logic"/>
</bean>

But in my test file (test-datasource.xml), if I used that format, no mapping files were found. I had to explicitly list each mapping file, like so:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
  <!-- setting test Hibernate properties here, blah, blah -->
  <property name="mappingResources">
    <list>
      <value>au/com/bisinfo/cmgr/logic/address/Address.hbm.xml</value>
      <value>au/com/bisinfo/cmgr/logic/country/Country.hbm.xml</value>
      <!-- repeat for 8 other mapping files -->
    </list>
  </property>
</bean>

It's ugly having to maintain this list of mapping files. Anyone know why the "mappingDirectoryLocations" approach doesn't work in my test cases (which extend AbstractTransactionalDataSourceSpringContextTests) ?

Whoops ... after reading another thread I have successfully used this format in my test datasource.xml file:

    <property name="mappingDirectoryLocations" value="file:target/classes"/>

... where "target/classes" is the Eclipse project folder that contains my root "au" package.

Now, back to the original question, and apologies if I was thread-jacking...

Great, specifying one single classpath works for my case as well.
Thanks.

[Correct]
<property name="mappingDirectoryLocations">
<list>
<set><value>classpath:/org/myspace/modele/configuration</value></set>
...
</list>
</property>

I m getting the same problem. I m not understand this."target/classes"
