Java.lang.NoClassDefFoundError: javax / persistence / Persistence

I am using NetBeans 6.8 and building a simple Maven web application project.

create Entity and main file to save the Entity [also create persistent block] and use EclipsLink.

but when i run main file get this error:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/persistence/Persistence
        at Main.main(Main.java:34)
Caused by: java.lang.ClassNotFoundException: javax.persistence.Persistence

        ... 1 more

in the netbeans projects window and in my project libraries folder add only this package:

Click Here to download hibernate-jpa-2.0-api-1.0.1.Final.jar

and place it in the project library, your application will work fine. Good luck :)

In yours, pom.xml

you need to add a dependency to the JPA libraries.

You just might stumble upon it. Another problem might be that you have a project importing another project, which is a parent project that should hold all libraries.
