<fault>
<faultcode faultType="_error">6</faultcode>
<faultstring xml:lang="en-US">Instance doesn't exist</faultstring>
</fault>
<UCPTname>Net/VirtCh/iLON
App</UCPTname>
</Item>
</iLonItem>
</SetResponse>
Example 3 (error occurs at the global level):
<SetResponse xmlns="http://wsdl.echelon.com/web_services_ns/ilon100/v4.0/message/">
<iLonItem>
<UCPTfaultCount>1</UCPTfaultCount>
<fault>
<faultcode faultType="_error">3</faultcode>
<faultstring xml:lang="en-US">invalid xSelect expression</faultstring>
</fault>
</iLonItem>
</SetResponse>
Because the error occurs at the global level (the error does not occur with a specific item instance),
none of the items are processed.
2.5.3.2 Fault Messages (SOAP Layer)
The SOAP fault message is a standard way to report back unexpected SOAP behavior to the originator
of the message. This response message has a different format than the response message for a message
call that succeeds, and it adheres to a standard format for SOAP 1.1 fault messages. In Version 4.0, all
applications will stop processing when an error occurs. In addition, the applications will return with
the following message:
<?xml version="1.0" encoding="utf8" ?>
<SOAP-ENV:Envelope SOAP-ENV:encodingStyle=http://schemas.xmlsoap.org/soap/encoding/
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<SOAP-ENV:Fault>
<SOAP-ENV:faultcode>1</SOAP-ENV:faultcode>
<SOAP-ENV:faultstring>soap
fault</SOAP-ENV:faultstring>
<SOAP-ENV:detail>Details</<SOAP-ENV:detail>>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
