I check which package contains this class and I found it in this maven dependency:

<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.0-api</artifactId>
</dependency>

I check if the Intellij add this jar to my executable jar and I found it there. So have someone any Idea where the problem is?


Indeed, hibernate-jpa-2.0-api contains this class.

It might be a classpath issue. Are you including required jar libraries in your jar? Can your app access other application provided jars at runtime? You may find the answers to this question useful: Classpath including JAR within a JAR


Try adding: javaee-api-5.0-2.jar to your project.


The JPA libs are a separate external download from Oracle. You may need to download them separately and install them into your local Maven repo.

You should also be specifying a version in your dependency XML.
