error while testing Hibernate JPA

I create a jUnit test to test my code, when I try to instatiate my object, I get this error

java.lang.IllegalAccessError: tried to access method org.hibernate.cfg.Configuration.<init>(Lorg/hibernate/cfg/SettingsFactory;)V from class org.hibernate.ejb.Ejb3Configuration

    at org.junit.internal.runners.JUnit38ClassRunner.run(JUnit38ClassRunner.java:83)

My code for my init method is 

protected void init() {
        emf = Persistence.createEntityManagerFactory("ceDataSessionData");

        em = emf.createEntityManager();
    }

My jUnit test is as 

 public void testApp()
    {
        CeReportDao reportDao = new CeReportDaoImpl();
        try {
            reportDao.getMoneyTransferReportJson(100, "TESTUSER1", "NS", null);
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

Question has been answered by @Vikdor:

Appears to be incompatible hibernate jars in the classpath. Could you list the hibernate related jars along with their versions?

That was the issue. I had a dependency project which was pulling a old version of entitiy classes for hibernate and this project was pulling the latest and hence.

I realize this is an old thread but I just thought I'd add one some extra info. I experienced this same problem with our Java 1.7 project using maven 3.3.3.

Our integration tests using Spring 3.1.4 were working fine until I added a hibernate-annotations (ver. 3.5.4) dependency to one of our artifacts. A downstream artifact then starting having the same IllegalAccessError mentioned above.

After spending hours trying to discover the cause of the issue, I was able to fix it by changing the hibernate-annotations dependency that I had previously added to a hibernate-entitymanager dependency. This fixed the downstream integration test problems.

My only point of mentioning this was to note that at no time did I have different versions of Hibernate jars on the classpath. Maven was showing all hibernate versions as 3.5.4 with the exception of a few jars that are supposed to have different versions (e.g., hibernate-common-annotations 3.2.0). So, I believe the comment above about having different Hibernate jars is not the issue in my case.
