Caused by: java.lang.RuntimeException: couldn't get connection at at org.mart.session.facade.MartFacadeBean.<clinit>(MartFacadeBean.java:64).null(Unknown Source)

-------------------------------------------------------------------------------------

this error is happening when the server executes the buidSessionFactory() on the cfg object :
.....

try
{
Configuration cfg = new Configuration().addClass(Make.class).addClass(model.class);

system.out.println ("construction of cfg object done");

sessionFactory = cfg.buildSessionFactory();
}

catch (Exception e){
throw new RuntimeException("couldn't get connection");
}

------------------------------------------------------------------------------------

Here's my hibernate.properties file :

-----------------------------------------------------------------------------------

#hibernate.connection.driver_class COM.ibm.db2.jdbc.app.DB2Driver
#hibernate.connection.url jdbc:db2:Project
#hibernate.connection.username
#hibernate.connection.password
#hibernate.dialect cirrus.hibernate.sql.DB2Dialect

## JNDI Datasource

hibernate.connection.datasource jdbc/ProjectDS
#hibernate.connection.username allo
#hibernate.connection.password allo

## to use JCS caching with JTA, Hibernate must be able to obtain the JTA TransactionManager
hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.WebSphereTransactionManagerLookup


#WebSphere
hibernate.jndi.class com.ibm.websphere.naming.WsnInitialContextFactory

-------------------------------------------------------------------------------------

My Datasource is seems to work well....

My version of hibernate is : version 2.1.3, 25 April 2004
Im using db2 udb 8.1

Here are my two mapping documents :

----------------------------------------

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

<hibernate-mapping>
<class name="org.mart.hibernate.Make" table="make">

<id name="makeID" column="makeID" type="int">
<generator class="assigned"/> </id>

<property name="description" column="description" type="string"/>

</class>

</hibernate-mapping>

--------------------------------------------------------------------------

here's my code between sessionFactory.openSession() and session.close()

--------------------------

Session session = sessionFactory.openSession();

System.out.println("opensession ");

List list = session.find("from model in class org.mart.hibernate.model");
session.flush();
session.close();


Thanks for your help !
