org.hibernate.MappingException: Resource: .hbm.xml not found

Hi - This was working...
Problem setup... I'm creating some common services which are packaged in a .jar file for use in applications. The persistant classes' .hbm.xml files are in the package in which the class resides. I have the Hibernate.cfg.xml located in the output directory of the eclipse project. So it seems Hibernate can locate the Hibernate.cfg.xml file but can not locate any of the mapped resources. I've looked around on for someone else with this problem, but haven't found anything relevent. Note the using application can find the classes I'm refering to.

Any assistence would be greatly appreciated.

Hibernate version: 3.1

Mapping documents:
Hibernate.cfg.xml:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>

<property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="connection.url">jdbc:oracle:thin:@xxxx:xxxx:xxxx</property>
<property name="connection.username">user</property>
<property name="connection.password">user</property>


<property name="connection.pool_size">1</property>

<property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>


<property name="show_sql">true</property>


<mapping resource=".\com\thomson\west\foundations\FoundationsOnWhatVO.hbm.xml"/>
<mapping resource="com\thomson\west\foundations\context\AppPropertyVO.hbm.xml"/>
... and more...
</session-factory>
</hibernate-configuration>

Code between sessionFactory.openSession() and session.close():

So the mapping files are not where you declare them in the config file

Code:

<mapping resource=".\com\thomson\west\foundations\FoundationsOnWhatVO.hbm.xml"/> 
<mapping resource="com\thomson\west\foundations\context\AppPropertyVO.hbm.xml"/>

Are you sure FoundationsOnWhatVO location starts with a "." for example?

No, sorry that was some test code, there should be no .\ in the front.

Basically when I use my created .jar file in a test application and I include the Hibernate.cfg.xml in the source folder of the test app then the test app can find my classes in the jar file and hibernate can find its Hibernate.cfg.xml but Hibernate can not seem to locate the various .hbm.xml resource files listed.

I have a workaround whereby when I add all the persistent classes within HibernateUtil in the process of building a session factory. The code ends up as such...

Code:

    public static final SessionFactory sessionFactory;

    static {
       String whereAmI = HibernateUtil.class.getName();
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            
           sessionFactory = new Configuration().configure()
           .addClass(com.thomson.west.foundations.FoundationsOnWhatVO.class)
           .addClass(AppPropertyVO.class)
           .addClass(TrAuditEventTypeVO.class)
           .addClass(TrAuditEventVO.class)
           .addClass(TrAuditValueVO.class)
           .addClass(ClobValueVO.class)
           .addClass(AppEventVO.class)
           .addClass(PropertyValueVO.class)
           .addClass(XPropertyVO.class)
           .addClass(ErrorValueVO.class)
           .addClass(ErrorEventVO.class)
           .addClass(ApplicationImpl.class)
           .addClass(com.thomson.west.foundations.security.server.AppFunctionalityVO.class)
           .addClass(FunctionalityVO.class)
           .addClass(RequiredRoleVO.class)
           .addClass(com.thomson.west.foundations.security.server.AppFuncReqRoleVO.class)
           .buildSessionFactory();

            //sessionFactory = new Configuration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
           String msg = new String();
           msg = whereAmI + " Initial SessionFactory creation failed." + ex.getMessage();
            log.error(msg);
            //ex.printStackTrace();
            ex.fillInStackTrace();
            throw new IssueEncounteredException(new ExceptionInInitializerError(ex), msg);
        }
    }

Which is not something which is exactly "pleasing" to me, but my delivery looms and I'm expecting few new classes in this service once I have the requirements met. On the otherhand the mappings are out of the Hibernate.cfg.xml where they could get futzed up by users... So maybe this is a good thing.

Thanks

Shouldnt this be

Code:

  <mapping resource="com/thomson/west/foundations/FoundationsOnWhatVO.hbm.xml"/>
     <mapping resource="com/thomson/west/foundations/context/AppPropertyVO.hbm.xml"/>
... and more...

Replaced the backward slashes with forward slashes!

I tried replacing the slashed, with no luck

So that wasn't it.

if u are using eclipse packaging, make sure that all hbm.xml files are packaged in to the jar files . i can happen sometimes :)

but as per the exception stack trace you have given ,
the problem is with the dot in front of mapping resource= ... line in hibernate.cfg.xml
