.configure(mycfg)....not found but its there.

MikeOliverAZ · **Posted:** Mon Jul 11, 2005 11:16 am

I am trying to debug the following code in Eclipse 3.0.

The configuration xml exists at "C:/Java/eclipse/workspace/HibernateStores/resources/Test/com.ajcs.hibernatestores.test.TestEvent/Hibernate.cfg.xml"

but it throws a not found exception. The TestEvent.hbm.xml also exists at the path specified and is the same hbm as found in the Event tutorial.

Hibernate version:Hibernate3.jar (3.0)

Code:

//constructor
public HibernateUtil(String cfgPath) {

   try {
      configuration = new Configuration().configure(cfgPath);
   } catch (HibernateException e) {
      e.printStackTrace();
   }

}

Hibernate.cfg.xml at that location

Code:

<?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">

I assume that you tried changing the '.'s to '/'s in this line?

<mapping
resource="C:/Java/eclipse/workspace/HibernateStores/resources/Test/com.ajcs.hibernatestores.test.TestEvent/TestEvent.hbm.xml"/>

The actual path to the file not found is:

Code:

C:\Java\eclipse\workspace\HibernateStores\resources\Test\com.ajcs.hibernatestores.test.TestEvent\Hibernate.cfg.xml

The same test suite has the following test case and does NOT fail:

Code:

public void testReadCfg() {
   File cfgFile = new File("/Java/eclipse/workspace/HibernateStores/resources/Test/com.ajcs.hibernatestores.test.TestEvent/Hibernate.cfg.xml");
   FileInputStream fis = null;
   try {
      if (cfgFile != null && cfgFile.exists()){
         fis = new FileInputStream( cfgFile );
         Assert.assertNotNull("Cannot open input stream",fis);
      }
   } catch (FileNotFoundException e) {
      Assert.fail(e.getLocalizedMessage());
   }
}

So does that mean that Hibernate treats the path to the file differently?

I think Hibernate uses ClassLoader.getResource()/getResourceAsStream():

/**
* Finds the resource with the given name. A resource is some data
* (images, audio, text, etc) that can be accessed by class code in a way
* that is independent of the location of the code.
*
* <p> The name of a resource is a '<tt>/</tt>'-separated path name that
* identifies the resource.
*
* <p> This method will first search the parent class loader for the
* resource; if the parent is <tt>null</tt> the path of the class loader
* built-in to the virtual machine is searched. That failing, this method
* will invoke {@link #findResource(String)} to find the resource. </p>
*
* @param name
* The resource name
*
* @return A <tt>URL</tt> object for reading the resource, or
* <tt>null</tt> if the resource could not be found or the invoker
* doesn't have adequate privileges to get the resource.
*
* @since 1.1
*/
public URL getResource(String name) {

Just to be sure that the dots in the file spec directory are NOT the problem, I changed the code and put copies of the Hibernate.cfg.xml up one directory and ran the test again.

So let me get this straight - in the source dir of your project, you now have a directory named resources with a subdir named Test and in that Test directory, your Hibernate.cfg.xml exists?

MikeOliverAZ · **Posted:** Mon Jul 11, 2005 2:37 pm

Ok a closer review of the JavaDocs and I see:

Code:

configure(String resource)

Use the mappings and properties specified in the given application resource. The format of the resource is defined in hibernate-configuration-3.0.dtd.

The resource is found via getConfigurationInputStream(resource). 

and

Code:

configure(File configFile)

    Use the mappings and properties specified in the given application file. The format of the file is defined in hibernate-configuration-3.0.dtd.

    Parameters:
        configFile - File from which you wish to load the configuration

So I changed my code to:

Code:

public HibernateUtil(String cfgPath) {

   try {
      File cfgFile = new File(cfgPath);
      configuration = new Configuration().configure(cfgFile);
   } catch (HibernateException e) {
      e.printStackTrace();
   }
}

SUCCESS!

But Now I am getting a similar mapping exception upon reading the configuration file.

Initial SessionFactory creation failed.java.lang.NullPointerException

So I looked in the dtd and found the change in the hibernate.cfg.xml to use a mapping file vs. a mapping resource so my Hibernate.cfg.xml looks like:

Code:

<?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="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
        <property name="hibernate.connection.url">jdbc:hsqldb:data/test</property>
        <property name="hibernate.connection.username">sa</property>
        <property name="hibernate.connection.password"></property>
        <property name="dialect">org.hibernate.dialect.HSQLDialect</property>
        <property name="show_sql">true</property>
        <property name="transaction.factory_class">
             org.hibernate.transaction.JDBCTransactionFactory
        </property>
        <property name="hibernate.cache.provider_class">
             org.hibernate.cache.HashtableCacheProvider
        </property>
        <property name="hibernate.hbm2ddl.auto">update</property>

        <mapping file="/Java/eclipse/workspace/HibernateStores/resources/Test/com.ajcs.hibernatestores.test.TestEvent/TestEvent.hbm.xml"/>

    </session-factory>

</hibernate-configuration>

And now it all WORKS!

Thanks and I hope this helps someone else.

Ok, but just bear in mind that won't work if you package things up in a JAR/WAR/EAR.

MikeOliverAZ · **Posted:** Mon Jul 11, 2005 2:57 pm

Right, this is a test harness, not to be deployed but to be used in development unit testing prior to deployment.
