org.hibernate.MappingNotFoundException: resource: *hbm.xml not found

Question

JBoss AS 7.0.1.Final, Hibernate 3. We have a MySQL datasource.

I have mapping resources pointing to *hbm.xml files. I get deployment errors that tell me 'resource: *hbm.xml not found', so entities are not being mapped correctly - this stack trace is due to the User.hbm.xml not being found,

Our project is structured like

Project
|
|-pom.xml
|
|-src
|  |-main
|     |-java
|     |   |-com... businessobjects
|     |-resources
|     |   |-META-INF
|     |-webapp
|
|-test

we have hibernate.cfg.xml in src/main/resources/META-INF, and various *.class and *hbm.xml in src/main/java/com/businessobjects/. Our hibernate.cfg.xml looks like

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="datasourceName">java:jboss/datasources/MySqlDS</property>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <mapping resource="com/mycompany/myapp/common/businessobjects/User.hbm.xml"/>
        <mapping resource="com/mycompany/myapp/common/businessobjects/Company.hbm.xml"/>
        <mapping resource="com/mycompany/myapp/common/businessobjects/ServerSettings.hbm.xml"/>
        <mapping resource="com/mycompany/myapp/common/businessobjects/Station.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

I've tried different paths to point to the *hbm.xml files - none seem to work. I've even tried giving it the absolute path to the *hbm.xml files, that didn't work either.

I've also tried copying the *hbm.xml into the same directory as hibernate.cfg.xml - that also didn't work, same error.

Looks like it errors out at this point in the code of my HibernateUtil class

static {
    try {
        InitialContext ctx = new InitialContext();
        Configuration configuration = new Configuration();
        Properties properties = new Properties();
        sessionFactory = configuration.configure(
            new File("/path/to/src/main/resources/META-INF/hibernate.cfg.xml")
            ).buildSessionFactory();
    } catch (Throwable ex) {
        // Make sure you log the exception, as it might be swallowed
        log.error("Initial SessionFactory lookup failed.", ex);
        throw new ExceptionInInitializerError(ex);
    }
}

Any ideas what's going on? Thanks

Answer 1

Move your mapping files into src/main/resources. Only .java files belong in src/main/java.

Edit: I've set up an example project on github showing how to correctly reference XML mapping files from a hibernate.cfg.xml.

Answer 2

Maven only processes .java files from src/main/java, so putting the .hbm.xml files into that part of the tree means they won't end up in the war file.

Maven picks up config files from src/main/resources and as you've mapped the .hbm.xml files with a path, they would need to go into src/main/resources/com/mycompany/myapp/common/businessobjects.

Hope that helps.
