Message Receiver not found for AxisOperation Exception

, ,
1

I declared an updating function (XQuery) to insert a new document, and then exported the module as a web service. When I call lasCRUD:create2 web service from SoapUI, I get the following exception:

org.apache.axis2.AxisFault: Message Receiver not found for AxisOperation: {http://namespaces.softwareag.com/tamino/lasCRUD}create2

Here is the updating function:

module namespace lasCRUD="http://namespaces.softwareag.com/tamino/lasCRUD";
declare namespace tf = "http://namespaces.softwareag.com/tamino/TaminoFunction"

declare updating function lasCRUD:create2( $filetype as xs:string, $filenum as xs:string, $legalText as xs:string, $inputDate as xs:string, $inputTime as xs:string, $transactionDate as xs:string, $userID as xs:string ) {
	let $record := collection('LAS')/LegalDescRecords[Control/FileType=$filetype and Control/FileNumber=$filenum]
	let $currentSequenceNum := fn:max( for $el in $record return $el/Control/Sequence )
	let $nextSequenceNum := $currentSequenceNum + 1
	let $ip := element LegalDescRecords {
		element Control {
			element FileType { $filetype },
			element FileNumber { $filenum },
			element Sequence { $nextSequenceNum },
			element InputDate { xs:date($inputDate) },
			element InputTime { xs:time($inputTime) },
			element TransactionDate { xs:date($transactionDate) },
			element UserID { $userID }
		},
		element LegalText { $legalText }
	}
	let $path := "LAS/LegalDescRecords"
	do(fn:put($ip, $path))
}

Is there something that I am not understanding correctly? I am able to call the lasCRUD:create2 function, for example from the following code in the XQuery editor:

import module namespace lasCRUD="http://namespaces.softwareag.com/tamino/lasCRUD";
declare namespace tf = "http://namespaces.softwareag.com/tamino/TaminoFunction"

update
do( 
	lasCRUD:create2('LAS', '1156', 'My test legal text.', '2013-11-06', '12:00:00', '2013-11-06', 'mdbergt') 
)

This code runs and successfully inserts a record. I attached the schema definition as well as a more detailed dump of the exception I am encountering. Thank you for the assistance.
