Estou usando o Hibernate para conectar-me ao PostgreSQL a partir de um contêiner Karaf 2.3.4. Quando implanto meu pacote, há uma exceção dizendo javax.naming.NameNotFoundException osgi:service/javax.sql.DataSource/"(osgi.jndi.service. nome=jdbc/postgresds).
Aqui está meu arquivo persistance.xml
<?xml version="1.0" encoding="UTF-8"?>

Resolvi esse problema e atualizei a lista de arquivos como disse M.Cristian, mas esse é outro problema estranho:ao reiniciar o Karaf e tentar inserir dados através do console do Karaf, o console imprime:Não há transação ativa, então tentei de outra forma usando o EntityManager e o problema não aparece mais.
Solução
Seu código não pode funcionar porque o DataSource é publicado no mesmo contexto do blueprint onde uma unidade de persistência é usada.
O problema é que o blueprint aguardará a injeção de um serviço EnitityManagerFactory.Portanto o DataSource nunca será publicado.Aries JPA detectará que deveria criar um EntityManagerFactory para seu pacote, mas atingirá o tempo limite ao tentar encontrar o DataSource.
Portanto, coloque o DataSource em um pacote rápido e ele deverá funcionar.
