Subject Guideline with schema condition maxOccurs="1"
Date Mon, 26 Sep 2005 09:22:46 GMT
Hi everyone,

I am developing a Web Services with wsdl described below and would like
to confirm with the AXIS behaviour.

I Invoked the service with the following SOAP request message, and it
returned the result properly.
<soapenv:Envelope 
	xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
	xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<soapenv:Body>
		<execXQuery
xmlns="http://www.mysite.org/MyWebServices.myws">
			<execQry xmlns="">
				<MyServices>
	
<MyServiceName>Svc1</MyServiceName>
					<reqElements>
						<elements>
	
<name>Name1</name>
	
<type>type1</type>
	
<value1>Hello</value1>
						</elements>
					</reqElements>
				</MyServices>
			</execQry>
		</execXQuery>
	</soapenv:Body>
</soapenv:Envelope>

Next, I modified the the <elements> tag to include multiple <value1>,
eg.
<elements>
	<name>Name1</name>
	<type>type1</type>
	<value1>Hello</value1>
	<value1>Yellow</value1>
</elements>

With modified SOAP request message, the AXIS on the service provider
side, took the 2nd <value1>, which is Yellow, to process the request.

>From what it has been declared in the WSDL, the <value1> tag has
maxOccurs="1".
My Questions are:
1. With maxOccurs="1", does AXIS always take only the last value within
same tag?
2. Is this how AXIS handles the restriction on the maxOccurs="1"?
3. Or must it throw an error, since the SOAP request does not follow the
schema rule?

Appreciate if someone could explain more, regarding this.


Thank you.
Herbert
