Can not create entity manager - IncompatibleClassChangeError

[___]

I am using Spring 3.0.5-Release, hibernate core 3.6.0.Final, hibernate-entitymanager 3.6.0.Final

When my test class tries to load application context, I am getting following error, whats going wrong ?

java.lang.IllegalStateException: Failed to load ApplicationContext

The error is clear

Caused by: org.springframework.beans.factory.BeanCreationExce ption:
Error creating bean with name 'complaintDao':
Injection of persistence dependencies failed; nested exception is
org.springframework.beans.factory.BeanCreationExce ption:
Error creating bean with name 'entityManagerFactory'
defined in class path resource [applicationContext-dao.xml]:
Invocation of init method failed; nested exception is java.lang.IncompatibleClassChangeError: Implementing class

Can you post the source code (xml, java), to get a better idea?

[___]

This is part of my applicationontext.xml

Dao's uses @PersistenceContext annotation.

<code>
<context:annotation-config />

<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerE ntityManagerFactoryBean">
<property name="persistenceUnitName" value="default_unit"/>
</bean>

<bean id="persistenceUnitManager"
class="org.springframework.orm.jpa.persistenceunit .DefaultPersistenceUnitManager">
<property name="persistenceXmlLocation">
<value>classpath:META-INF/persistence.xml</value>
</property>
</bean>


</code>

[dr_pompeii]

Use code tags < code > </code > , replace < > by [ ]

Why are you using
org.springframework.orm.jpa.persistenceunit.Defaul tPersistenceUnitManager ?

Show the persistence.xml content I assume in there should be located the bold part below

<persistence ...>
<persistence-unit name="default_unit" />
</persistence>

[___]

Here's persistence.xml

I believe, its not the issue of configuration (as it works with the hibernate 3.3.2)
Its the issue of compatibility

Now that you did mention about that, I recall this problem, but when
hibernate 3.6.0 or 3.5.x was just released, I suggest you did a search in the forum, I recall have read 1 o 2 threads about this

I thought it was already solved with a new release of Spring

BTW, try it with
hibernate core 3.5.x, hibernate-entitymanager 3.5.x, if work then is a problem of version

Consider too if is critical for you work mandatory with 3.6.0

Let me know your advance

[___]

Works with Hibernate 3.5.6-Final

[dr_pompeii]

Works with Hibernate 3.5.6-Final

OK
two things

1) Work with 3.5.6, is really mandatory for your work with 3.6.0?
2) I have Spring 3.0.4 and according with its changelog

* support for Hibernate Core 3.6, Hibernate Validator 4.1, EclipseLink 2.1, EHCache 2.2

none mention to hibernate-entitymanager 3.6.0

If in Spring 3.0.5 has or appear practically the same, you must wait then, it scape of our hands

[qualcommLisa]

We've been struggling with this problem for days now. I'm using Spring 3.0.5.RELEASE and trying to deploy to tc-server-developer-2.1.1.RELEASE with absolutely NO success! I've tried multiple hibernate versions, including the ones mentioned in this thread, and so far no success.

Can someone please look into why this is still happening with 3.0.5.RELEASE?

I encountered this error while using joda-time-hibernate, which depends on very old hibernate version. Check if you don't have two hibernate jars in your maven dependencies. Exclude in maven pom file solved the issue.

<dependency>
  <groupId>joda-time</groupId>
  <artifactId>joda-time-hibernate</artifactId>
  <version>1.2</version>
  <exclusions>
    <exclusion>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate</artifactId>					
    </exclusion>
  </exclusions>
</dependency>
