Hi! I'm having problems running a Google App Engine app (GAE/J) trying
to integrate with JPA but I can't make it work. I followed the simple
steps of google official tutorial (http://code.google.com/appengine/
docs/java/datastore/jpa/overview.html). I setted up the
persistence.xml file in the right place, downloaded the JAR from the
SDK and added to my project as external JARs (using Eclipse SDK). I'm
currently not using Maven so i'm doing it manually.
When I run the GAE application the following WARNINGs, ERRORs and
Exceptions appear on my Console:

com.google.appengine.tools.development.DevAppServerImpl start
INFO: The server is running at http://localhost:8888/
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
After this the app starts, but the JPA example that i have doesn't
work...
What i'm doing wrong? What is this error? Do I need to configure
anything else? Download a plugin ? Any idea... Any happy tutorial ?
Thanx!
