Hi,
I am new using Google App Engine, I am following the tutorial
http://www.vogella.com/tutorials/GoogleAppEngineJava/article.html to learn
it.
I am continuously getting this error when I run the application.
NOTE: I have read almost all the posts for this, but couldn't find any
solution for this problem:

http://stackoverflow.com/questions/16482385/google-app-engine-jpa-java-server-faces-uncaught-exception-from-servlet-java-l
Can someone provide a suitable solution for this problem? The error is on
the line:
*private static final EntityManagerFactory emfInstance =
Persistence.createEntityManagerFactory("transactions-optional");*
and
*EntityManager em = EMFService.get().createEntityManager();*
Thanks..
