InvocationTargetException in session.createQuery("from

Hallo everbody,

I'm new to Hibernate and I am trying to run the example (chapter 1) of the reference documentation (Events, Persons, ...).

Unfortunately there seems to be a big problem while using the line of code

Code:

List result = session.createQuery("from Event").list();

The following Exception ist thrown:

Code:

Exception in thread "main" java.lang.reflect.UndeclaredThrowableException
   at $Proxy0.createQuery(Unknown Source)
   at events.EventManager.listEvents(EventManager.java:79)
   at events.EventManager.main(EventManager.java:18)

   at org.hibernate.impl.AbstractSessionImpl.createQuery(AbstractSessionImpl.java:88)
   at org.hibernate.impl.SessionImpl.createQuery(SessionImpl.java:1540)
   ... 8 more

Hibernate version:
3.1

Mapping documents:
Indentical to introductory example printed in chapter 1 of the reference doc.

Code between sessionFactory.openSession() and session.close():
indentical to the introduction (chapter 1 of reference doc)

The Problem occurs using Java 5.0 and JDK 1.4.

I have checked everything very carfully and the forum doesn't seem to offer o document addressing this problem. So, please, could someone give me a hint, what to do?

Thanks in advance

Hi,

I think you have not added the required jars for Hibernate in the BUILD PATH. eg) antlr.jar

Hi Ramnath,

thank you for your hint. Well, yes, my problem was caused by missing libraries. Let me explain:

I used all the JARs that were requested by the tutorial (see part 1.2 of the reference doc):

Code:

antlr.jar
  cglib.jar
  asm.jar
  asm-attrs.jars
  commons-collections.jar
  commons-logging.jar
  hibernate3.jar
  jta.jar
  dom4j.jar
  log4j.jar

So, antlr.jar was never missing. As a result of your suggestion I have linked all JARs that come with hibernate and now it works.

So, maybe there are some inconsistencies between the documentation (chapter 1) and the software.

Thanks and a happy new year!

Peter
