XML Message Body Selector in Automation

Question

Hi,
I'm having some trouble implementing a XML Message Body Selector in an automated task. I'm running OSM 7.2.0.7 in a Unix environment and using Design Studio 7.2.1.
I'm sendind in my request to an external system a request tthe following string: OSM-TaskName-%{CARTRIDGE_VERSION}
<Request>
    <Header>
        <dueDate>20131128</dueDate>
        <application>OSM-MSS_Lookup-1.0.0.0.5</application>
    </Header>
</Request>
The response of MSS is:
<Response>
    <Header>
        <dueDate>20131128</dueDate>
        <application>OSM-MSS_Lookup-1.0.0.0.5</application>
    </Header>
In the selector I've tried different XPath expressions:
Select:
/*[local-name() ='Response']/*[local-name()='Header']/*[local-name()='application']/text()
*[local-name() ='Responset']/*[local-name()='Header']/*[local-name()='application']/text()
//*[local-name() ='Response']/*[local-name()='Header']/*[local-name()='application']/text()
/*[local-name() ='Response']/*[local-name()='Header']/*[local-name()='application']
*[local-name() ='Response']/*[local-name()='Header']/*[local-name()='application']
//*[local-name() ='Response']/*[local-name()='Header']/*[local-name()='application']
/Response/Header/application
/Response/Header/application/text()
Compare: OSM-MSS_Lookup-%{CARTRIDGE_VERSION}
I keep getting the following error in the log file for the differente selectors:

I would appreciate any help or ideas.
Cheers

Answer 1

Hi,
Could you confirm on below:
1 ) Are you using multiple automation plug-in external event receivers in the same automation task ?
2 ) And are you having the default Correlation Message property set to 'JSMCorrelationID' in external event receiver?
If your answer for the first question is No, they i would suggest to use Correlation XML Body as
*[local-name() ='Response']/*[local-name()='Header']/*[local-name()='application']
The value of the field(application) in request must match the value of the field in response, in your case it is matching. And you will be reading this correlation id in response processing xquery.
