JPA 2 project template
======================
General:
--------
Executing »`mvn test`« generates metamodel classes being required for
criteria based queries.
Eclipse users:
--------------
You will have to execute »`mvn test`« manually from the command line or by right
clicking on your project's root choosing »`Run As`« - - > »`Maven test`«. This will
trigger the metamodel generating process resolving a compile time error in
class »`SearchByIcao`«.
