HI Aditya,
I tried the attached configs in the mail thread and could get expected
output as in above. Sorry for missing the point of backend service.
The xpath *get-property('firstResponse')/children* works for me and it will
add elements to *children* element as in your config. Hope you are trying
with a new ESB version.
*EnrichMediator} - Invalid Target object to be enrich *error can be happened
for xpath *get-property('firstResponse')/children, *if there is no
'firstResponse' is formed before 'aggrementResponse'. The aggregated result
from the backend service can be as following when aggregating results. So
there will be not be 'firstResponse' before 'aggrementResponse and that
error will be occured. Same can be happened with
*xpath="$ctx:firstResponse".*
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";>
<soapenv:Body>
<Information>
<jsonObject>
<id>3</id>
<make>Tamsung</make>
<name>Mobile</name>
<model>S8</model>
</jsonObject>
<jsonObject>
<id>1</id>
<make>TAHB</make>
<children>
<kid>1</kid>
</children>
<children>
<kid>2</kid>
</children>
<name>Home</name>
<area>5000sqft</area>
</jsonObject>
<jsonObject>
<id>2</id>
<make>Tonda</make>
<name>Car</name>
<model>Tmaze</model>
</jsonObject>
</Information>
</soapenv:Body>
</soapenv:Envelope>
Assuming that your backend gives mentioned output by you, Can you try by
adding PayloadFactory mediator to your main.xml as in below.
<default>
-----------------------------------------------------------
<payloadFactory media-type="xml">
<format>
<jsonObject xmlns="">
<id>$1</id>
<children xmlns="">
<id>$1</id>
<make>$2</make>
<name>$3</name>
<model>$4</model>
</children>
</jsonObject>
</format>
<args>
<arg evaluator="xml" expression="//jsonObject/id"/>
<arg evaluator="xml" expression="//jsonObject/make"/>
<arg evaluator="xml" expression="//jsonObject/name"/>
<arg evaluator="xml" expression="//jsonObject/model"/>
</args>
</payloadFactory>
<property name="aggrementResponse"
expression="//jsonObject/children"
scope="default"
type="OM"/>
<enrich>
<source
xpath="get-property('aggrementResponse')"/>
<target action="sibling"
xpath="get-property('firstResponse')/children"/>
</enrich>
</default>
--------------------------------------------------------------------
<enrich>
<source clone="true"
xpath="get-property('firstResponse')"/>
<target type="body"/>
</enrich>
------------------------------------------------------------------------
<property name="messageType" value="application/json" scope="axis2"/>
This worked for me.
Thanks
Sudharma
