Hi All,

I am new to hibernate world.
I have written a small appllication in JSF+Hibernate.
I have all the required jar files and here is the code:

First the hibernate.cfg.xml file

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>

        <!-- Database connection settings -->
        <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
        <property name="connection.url">localhost</property>
        <property name="connection.username">root</property>
        <property name="connection.password"></property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.OracleDialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">update</property>
 
       <mapping resource="test.hbm.xml"/> 
       
         
    </session-factory>

</hibernate-configuration>



Now the test.hbm.xml


Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
  <class name="com.myhibernate.classes.TestHibernate" table="HIBERNATE_TEST">
   <id name="id" type="int" column="ID" >
   <generator class="assigned"/>
  </id>

  <property name="name">
   <column name="NAME" />
  </property>
</class>
</hibernate-mapping>


is there anything wrong with these files.

Looks good but anyway in detail it really depends on which environment exactly you want to have (hibernate-version, database-version, etc.).
Do you get exceptions when starting you sample-app?
Can you report the exceptio with stacktraces?
