Проблема с настройкой river-jdbc oracle

Question

Я пытаюсь использовать плагин asticsearch river-jdbc с базой данных Oracle. При создании реки я получил исключение:

[2014-12-10 11:42:44,795][WARN ][river                    ] [Agent Axis] failed to create river [jdbc][quotes]

    ... 9 more

Драйвер jdbc oracle ojdbc7.jar (версия x64) находится в папке $ES_HOME/plugins/jdbc, а также в папке $ES_HOME/lib.

Я работаю с FlexibleSearch v1.4.0 под Windows 7 x64,asticsearch-river-jdbc-1.4.0.3.Beta1.

вот конфиг реки:

PUT _river/quotes/_meta 
{
    "type" : "jdbc",
    "jdbc" : {
        "url" : "jdbc:oracle:thin@//localhost:1520/test",
        "user" : user,
        "password" : pwd,
        "sql" : {
            "statement" : "select id as \"_id\",quotes.* from quotes where mytimestamp > ?",
            "parameter" : ["$river.state.last_active_begin"]
        },
        "index" : "quotes",
        "type" : "quote"
    }
}

я не вижу, чего не хватает в моей настройке

С уважением
