SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#noProviders for further details. And then I don't see any logs printed by my servlet with Logger LOG = Log.getLogger(LOG_TAG); LOG.info("...."); And thus I cannot find out why there is no data returned from PostgreSQL... Maybe this line does not really work? factory.setCreator(new WordsCreator(this, mBundle.getString(STR_DATABASE_URL))); My servlet is multilanguage and thus I was passing differen DB credentials with the line above. What should I please use instead instead of Log.getLogger()? There is @deprecated, but no replacement suggestion.
