I have a problem to iterate over call response of a dss. I have 2 servers
WSO2 ESB server (4.9.0) WSO2 Application Server (5.3.0) with Data Service (4.3.4) feature installed
i make a payload
<payloadFactory media-type="xml">
<format>
<p:valoresReport xmlns:p="ReportsDataService">
<xs:uuid xmlns:xs="ReportsDataService">$1</xs:uuid>
</p:valoresReport>
</format>
<args>
<arg value="123456789"/>
</args>
</payloadFactory>
and do a call through an endpoint
<call blocking="true">
<endpoint key="ReportsDataServiceEndPoint"/>
</call>
The response is:
<ReportRowSet xmlns="ReportsDataService">
<reportRow>
<column1>1</column1>
<column2>2</column2>
<column3>3</column3>
</reportRow>
<reportRow>
<column1>columna 1</column1>
<column2>olumna 2</column2>
<column3>columna 3</column3>
</reportRow>
</ReportRowSet>
To read the response, i change de messageType to json
<property name="messageType" scope="axis2" type="STRING" value="application/json"/>
and get the value with json-eval.
<property expression="json-eval($.ReportRowSet.reportRow)" name="rows"
scope="default" type="STRING"/>
I can log the property
<log level="custom">
<property expression="$ctx:rows" name="ROWS"/>
</log>
output:
[2016-05-31 16:21:38,489] INFO - LogMediator ROWS = [{"column1":1,"column3":3,"column2":2},{"column1":"columna 1","column3":"columna 3","column2":"olumna 2"}]
But when i try to iterate the rows, i dont know how to do this (this way does not work)
<iterate continueParent="true" expression="$ctx:rows"
id="MyIterator" sequential="true">
<target>
<sequence>
...
also i tried with no success (without changing the messagetype):
<iterate continueParent="true" expression="//ReportRowSet/reportRow"
id="MyIterator" sequential="true">
whats the correct form to do this integration and iteration.
I let you my dss and sequence:
ReportsDataService.dbs: [ https://drive.google.com/open?id=0B44t8SdKZz79ellKVmpkM0t6Rmc ]
GenerarReporteSequence.xml: [ https://drive.google.com/open?id=0B44t8SdKZz79YlkxMnNnNm8weGs ]
Try with proper namespace in your iterator mediator, sample below,
<iterate xmlns:ns1="ReportsDataService" id="MyIterator" expression="//ns1:ReportRowSet/ns1:reportRow" sequential="true">
<target>
<sequence>
<log level="custom">
<property name="col" expression="//ns1:column1"/>
</log>
<call>
<endpoint>
<http uri-template="http://endpoint.url"/>
</endpoint>
</call>
</sequence>
</target>
</iterate>
