Error creating EntityManagerFactory, IllegalAccessError

Hello,

When I try to create the EntityManagerFactory I get this error:

Quote:

java.lang.IllegalAccessError: tried to access method org.hibernate.engine.CascadeStyle.<init>()V from class org.hibernate.engine.EJB3CascadeStyle$1
at org.hibernate.engine.EJB3CascadeStyle$1.<init>(EJB3CascadeStyle.java:24)

at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:119)
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:51)

I don't understand why this. What can I do to solve this?

Hibernate Core 3.2.6.ga
Hibernate Annotations 3.3.0 GA
Hibernate EntityManager 3.3.1 GA[/quote]

you have an old hibernate jar somewhere.

log4j-1.2.16
hibernate-commons-annotations-3.2.0.final
dom4j-1.6.1
sl4j-api-1.6.4
log4j-over-sl4j-1.6.4

I, too, am getting the error:
java.lang.IllegalAccessError: tried to access method org.hibernate.cfg.Configuration.<init>(Lorg/hibernate/cfg/SettingsFactory;)V from class org.hibernate.ejb.Ejb3Configuration
when executing this line:

Code:

emFactory = Persistence.createEntityManagerFactory("practice");

I am following along in the Java Persistence with Hibernate book trying to learn Hibernate. Everything was going very well until they switched from SessionFactory to EntityManagerFactory. I am using:

Code:

hibernate-core-4.1.1.Final.jar
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
javassist-3.15.0-GA.jar
hibernate-entitymanager-3.3.2.GA.jar
hibernate-c3p0-4.1.1.Final.jar
log4j-1.2.15.jar
...

I don't think it is because of an old hibernate jar. But Hibernate is new to me. Any ideas?
...

you need hibernate-entitymanager-4.1.1.Final.jar not the version 3.3.2.GA
