I've solved this problem already. The problem was that persistence.xml file must be placed in classpath\META-INF
directory, NOT in \META-INF directory of jar file. This unobvious thing is specified in JPA specification.

Goddamn Glassfish stacktracing! It was impossible to know that persistese.xml
was not found where needed looking on stacktrace. Why didn't application deploy
fail? Even more, persistence.xml was validated when deploying application (fails when
there are errors in persistence.xml). [Message sent by forum member 'nosferatum']
