Hi Georg,

It looks like you don't have a JPA implementation on the class path. JPA can be used just fine in a regular Java client program. Ensure that you have a persistence.xml file in the META-INF directory of your application JAR configured for use outside the container (there are some slight differences). You can either explicitly list the persistence provider or if there is only a single provider on the classpath it should be found automatically.
