Служба данных WSO2 (DS) в ESB 4.0.3 возвращает неверное сообщение об ошибке

Я работаю в Apple, и мы работаем над прототипом, использующим WSO2 ESB с функцией Data Services. Я использую WSO2 ESB 4.0.3 с функцией DSS. Я развернул службу данных и вызвал ее из прокси-службы в ESB. Я использую MAC OS X 10.7.4, и сведения о версии Java приведены ниже.

версия java "1.6.0_31" Java (TM) SE Runtime Environment (сборка 1.6.0_31-b04-415-11M3635) 64-разрядная серверная виртуальная машина Java HotSpot (TM) (сборка 20.6-b01-415, смешанный режим)

Моя служба DS ожидает определенного параметра, например параметра A, и я не передаю этот параметр во входном XML. Я вижу следующую ошибку на консоли WSO2 ESB.

Глядя на ошибку SOAP, я должен вернуть сообщение об ошибке клиенту, но даже подумал, что правильное сообщение об ошибке должно быть «Отсутствует параметр». Текст причины ошибки SOAP - «javax.xml.stream.XMLStreamException»

Я делаю что-то не так, или это ОШИБКА в DSS?

Посмотрев на трассировку стека, я вижу, что вы включили трассировщик SOAP при вызове службы, отключили трассировщик SOAP и должны получить правильное сообщение об ошибке.

Ура, Анджана.

Как объясняется в сообщении об ошибке, ожидаются входные параметры, которые не поступают в запрос. Это можно исправить двумя способами:

  1. Передача пустого тега из ESB без значения.
  2. Установите значение по умолчанию в DSS.

Первый вариант работает со всеми версиями, вот пример установки значения по умолчанию.

<payloadFactory media-type="xml">
    <format>
        <ds:DATA_SERVICE_REQUST xmlns:ds="http://ws.wso2.org/dataservice">
            <ds:INPUT_PARAM_1>$1</ds:INPUT_PARAM_1>
        </ds:DATA_SERVICE_REQUST>
    </format>
    <args>
        <arg xmlns:ds="http://ws.wso2.org/dataservice" evaluator="xml" expression="get-property('INPUT_PARAMETER')"/>
    </args>
</payloadFactory>
<call>
    <endpoint>
        <address uri="DSS_END_POINT"/>
   </endpoint>
</call>

Для второго варианта проверьте свою версию DSS, поддерживает ли она нулевые значения

Последняя версия DSS Поддерживает значения параметров по умолчанию в списке параметров запроса. Не могли бы вы попробовать, добавив defaultValue="#{NULL}" в список параметров запроса в вашем файле службы данных (dbs)?

<query id="QUERY-ID" useConfig="DATA-SOURCE-ID">
    <sql>-------------SQL QUERY HERE -----</sql>
    <result ----------- >
        <element ------------ />  
    </result>
    <param defaultValue="#{NULL}" name="PARAM-NAME" ordinal="1" sqlType="INTEGER"/>
</query>

Если эта проблема все еще не решена, было бы хорошо, если бы вы могли предоставить сведения о своем API.
