Basically, it's complaining that JPA2 libraries aren't installed.
       
Solution

1. Stop the Websphere7 server.
2. Install "OSGi Applications and Java Persistence API (JPA) 2.0 feature pack" using "IBM Installation Manager"
1. http://www-01.ibm.com/software/webservers/appserv/was/featurepacks/osgi/instopt/index.html
3. At the last step of the installation, select "Open Profile Management Tool"
4. From the "Profile Management Tool 7.0" window...
5. Go to the "Profile Management Tool" tab
6. Select the relevant profile.
7. Select "Augment..."
8. At "Select the augment to apply to the selected profile", select "Application server with Java Persistence API 2.0 feature"
9. Apply, then Exit the tool.
10. Start up the Websphere7 server.

Additional Notes

Problem: The Installation Manager does not synchronize with WebSphere Application Server if WebSphere Application Server is at higher fix pack level than recommended for the feature pack.

Solution: Download the latest version of WebSphere Application Server import repositories and add it to the Installation Manager:

Solution

1. Remove hibernate-jpa-2.0-api-1.0.0.Final.jar from your war file, and add it as a shared library to your application. 
2. Make sure you restart your application.

N.B. You shouldn't need to do this if you've setup the shared library correctly, but if you're still having trouble, it might help if you have the following classloading strategy enabled - Classes loaded with local class loader first (parent last)

Caused by: org.hibernate.HibernateException: Could not obtain WebSphere TransactionManager

Problem

Received the following stacktrace from Websphere7.

Caused by: org.hibernate.HibernateException: Could not obtain WebSphere TransactionManager
(Stack trace removed...)
Caused by: java.lang.ClassCastException: com.ibm.ws.tx.jta.TranManagerSet incompatible with javax.transaction.TransactionManager


Solution

Make sure you have the following transaction manager lookup class in your persistence.xml.

<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.WebSphereExtendedJTATransactionLookup" />
