- Para a construção de um Lambda" é necessário o descritor de pacote "template.yaml".
Lembrando que a classe que implementa "RequestStreamHandler" será "Singleton" até a JVM sair da instancia (kill).

</dependency>- Usando o "Maven Shade", fará um pacote único de jar.
Terminando o exemplo de Lambda, continuei com o exemplo de Drools.
O arquivo "kmodule.xml" foi necessário para o Drools funcionar. Não testei se as regras podem ficar em outro diretório que não seja o "rules/". O pacote das regras esta como "com.sample" para exemplificar o DRL com o uso de "import".
Neste exemplo, o Drools executa as regras no classpath simples assim:
KieServices ks = KieServices.Factory.get();
KieContainer kContainer = ks.getKieClasspathContainer();
KieSession kSession = kContainer.newKieSession("ksession-rules");
kSession.fireAllRules();TODO: Fazer o Lambda receber um JSON com o DRL, executar e devolver outro JSON.
