hibernate.cfg.xml question

Hi guys,

I am working on the first tutorial on Hibernate. Did everything, and compilation went fine. However, when I try to run ant run -Daction=store I get errors regarding hibernate.cfg.xml file:

Code:

[alex@localhost hibernate_test.war]$ ant run -Daction=store
Buildfile: build.xml

clean:
   [delete] Deleting directory /home/jboss-4.0.2/server/default/deploy/hibernate_test.war/bin

    [javac] Compiling 3 source files to /home/jboss-4.0.2/server/default/deploy/hibernate_test.war/bin

     [java]     ... 5 more
     [java] Java Result: 1

BUILD SUCCESSFUL
Total time: 7 seconds

As I understand from the tutorial once I put hibernate.cfg.xml into src directory ant will pick it up and put into bin directory and in turn wrapper will try to read the file by default:

Code:

sessionFactory = new Configuration().configure().buildSessionFactory();

So does the error mean that file could not be read or there is something wrong in the file?

thanks a lot,
webtekie

Post your configuration file. It appears it not well formatted.

thanks Richard,
yes it was poor formatting of the file. But, now I get error regarding datasource:

Code:

and here is my cfg.xml file:

Code:

<?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>

    <!-- a SessionFactory instance listed as /jndi/name -->
    <session-factory
        name="java:hibernate/SessionFactory">

        <!-- properties -->
        <property name="connection.datasource">java:/mydb</property>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="show_sql">false</property>
        <property name="transaction.factory_class">
            org.hibernate.transaction.JTATransactionFactory
        </property>
        <property name="jta.UserTransaction">java:comp/UserTransaction</property>

        <!-- mapping files -->
        <mapping resource="SKU.hbm.xml"/>

        <!-- cache settings -->

    </session-factory>

</hibernate-configuration>

I know connection to database works because I tested it straight to JDBC from my own class, so what could be the issue?

thanks again,
webtekie

This error has to do with your environment.

Specifically

Code:

Caused by: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resour
ce file:  java.naming.factory.initial 

Are you running this inside an AppServer ?

yes, jboss 4.0.2.
What env should I set?

They should be set in -...\jboss-4.0.2\server\default\conf\jndi.properties should have it defined. Not sure why it would've changed.

thanks, but the file says:

Code:

# DO NOT EDIT THIS FILE UNLESS YOU KNOW WHAT YOU ARE DOING
#
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

And I don't know what I am doing with this file so help is greatly appreciated.

thanks again,
webtekie

Also,

In reference it says:

Code:

Note that this class [HibernateUtil] is not necessary if you deploy Hibernate in a J2EE application server: a Session will be automatically bound to the current JTA transaction and you can look up the SessionFactory through JNDI. If you use JBoss AS, Hibernate can be deployed as a managed system service and will automatically bind the SessionFactory to a JNDI name.

So how do I deploy Hibernate as a managed system service?
