Full stack trace of any exception that occurs:

Name and version of the database you are using:
PostGreSQL Database Server 8.3
I want to have a simple Eclipse RCP Application to access the Database, i am surely missing a detail, cause im still very new to using Hibernate.
I read some Forums and most suggestions say some Jars are missing. I put all Jars i could find in hibernate core, annotations and entity manager into one Plug-In(using "create Plug-In from JAR Files") and added the Plug-In to the Dependencies of the RCP.
List of JARs in the Plug-In:
xml-apis.jar
ant-1.6.5.jar
ant-antlr-1.6.5.jar
ant-junit-1.6.5.jar
ant-launcher-1.6.5.jar

I put persistence.xml into META-INF of the RCP.
Looks like this
Code:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
xmlns="http://java.sun.com/xml/ns/persistence"

<!-- debug properties -->

<property name="hibernate.show_sql" value="true"/>
</properties>
</persistence-unit>
</persistence>
Exception occurs in line ".createEntityManagerFactory(...)":
Code:
private static final EntityManagerFactory entityManagerFactory;
static {
try {
// Create the EntityManagerFactory
entityManagerFactory = Persistence.createEntityManagerFactory("manager1", new Properties());
} catch (Throwable e) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial EntityManagerFactory creation failed." + e);
throw new ExceptionInInitializerError(e);
}
}
I want to map a single Class called "Adress":
Code:
@Entity
public class Address implements Comparable<Address>, Cloneable, Serializable {
private static final long serialVersionUID = 1L;
private Long id;
private String city;
private String country;
private String street;
private String zip;
/**
* @return the id
*/
@Id @GeneratedValue
public Long getId() {
return id;
}
The calling class looks like this:
Code:
/**
* Application boot trap
* @param args
*/
public static void main(String[] args) {
// setup log4j logging facility
try {
SimpleLayout layout = new SimpleLayout();
ConsoleAppender consoleAppender = new ConsoleAppender( layout );
logger.addAppender( consoleAppender );
FileAppender fileAppender = new FileAppender( layout, "logfile.log", false );
logger.addAppender( fileAppender );
logger.setLevel( Level.DEBUG );
} catch( Exception ex ) {
System.out.println( ex );
}
// run DB Test DBTest
new DBTest().run();
public void run() {
// store Address object
Address address = new Address();
address.setCity("Stuttgard");
address.setCountry("Germany");
address.setStreet("Waldweg 45");
address.setZip("58421");
saveAddress(address);
/**
* Store an address object.
* @param address
*/
private void saveAddress(final Address address) {
EntityManager em = HibernateUtil.getEntityManager();
EntityTransaction tx = em.getTransaction();
tx.begin();
em.merge(address);
tx.commit();
em.close();
}
I just have the question wich point i'm missing or if there are any hints or known problems...
excuse me for the long post, i just wanna give all necessary information.
with beste regards
