Hallo zusammen,
ich hab grade mit Hibernate angefangen und versucht ein Beispiel auszuführen. Es geht leider nicht wegen einem Bug das ich nicht weiss warum. Bitte mal helfen.
Die Felhlermeldung sieht so aus :
Exception in thread "main" java.lang.NoClassDefFoundError: org/dom4j/DocumentException
at Test.main(Test.java:9)
Caused by: java.lang.ClassNotFoundException: org.dom4j.DocumentException

Hier ist meine SourceCode :
// Java Class "Message" :package hello;
import java.io.Serializable;
public class Message implements Serializable{
private int id;
private String text;
public Message() {}
public Message(String text) {
this.text = text;
}
public int getId() {
return id;
}
private void setId(int id) {
this.id = id;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
}

Session session = factory.openSession();
Transaction tx = session.beginTransaction();
hello.Message message = new hello.Message("Hello World 2");
session.save(message);
System.out.println(message.getText());
tx.commit();
session.close();
}
}
und ich habe diese Fehlermeldung bekommen :
