minOccurs and nillable
Hi,
I am using a WSDL file supplied to be by a third party and I suspect it
doesn't quite reflect what their .NET server is returning in the SOAP
messages. I am getting this exception:
java.io.IOException: Non nillable element 'requestCategoryCode' is null.

So looking at (an extract of) the XML received by Axis:
<AdministrationDetails><ComplaintTypeCode>PESTM</ComplaintTypeCode><Com
plaintTypeText>Mice</ComplaintTypeText><AllocatedToCode>CRMTES</AllocatedToCode>
<AllocatedToText>CRM Test
Officer</AllocatedToText><HowReceivedCode>CC</HowRecei
vedCode><HowReceivedText>Call
Centre</HowReceivedText><TimeReceived>2005-08-04T0
6:52:03.0000000+01:00</TimeReceived><StatusCode>REC</StatusCode><StatusText>Rece
ived</StatusText><AreaTeamCode>E</AreaTeamCode><AreaTeamText>Eastern Area
Team</
AreaTeamText></AdministrationDetails>
And here's the relevant part of the WSDL:
<xs:complexType name="AdministrationDetailsType">
<xs:annotation>
<xs:documentation>Contains details of status,
allocated officer
codes etc</xs:documentation>
</xs:annotation>
<xs:sequence>
<xs:element name="ComplaintTypeCode"
type="uni:CNCODE_CodeValue">
<xs:annotation>
<xs:documentation>Code
value for complaint
type</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="ComplaintTypeText"
type="uni:CNCODE_TextValue">
<xs:annotation>
<xs:documentation>Full text of complaint type - read
only</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="RequestCategoryCode"
type="uni:CNCODE_CodeValue">
<xs:annotation>
<xs:documentation>complaint type category code if set
</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="AllocatedToCode" type="uni:CNCODE_CodeValue">
<xs:annotation>
<xs:documentation>Officer code for
allocated officer</xs:documenta
tion>
</xs:annotation>
</xs:element>
<xs:element name="AllocatedToText"
type="uni:CNCODE_TextValue">
<xs:annotation>
<xs:documentation>Full name of allocated
officer</xs:documentation
>
</xs:annotation>
</xs:element>
<xs:element name="TimeAllocated"
type="xs:dateTime" minOccurs="0">
<xs:annotation>
<xs:documentation>The date and time the request
was allocated to a
n officer to investigate</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="HowReceivedCode"
type="uni:CNCODE_CodeValue">
<xs:annotation>
<xs:documentation>Code value indicating how the
complaint was rece
ived</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="HowReceivedText"
type="uni:CNCODE_TextValue">
<xs:annotation>
<xs:documentation>Full description of how received
code</xs:docume
ntation>
</xs:annotation>
</xs:element>
(etc.)
It would seem to me that this change needs to be made:
<xs:element name="RequestCategoryCode" type="uni:CNCODE_CodeValue"
minOccurs="0" nillable="true">
As the .NET server has not sent back a RequestCategoryCode element.
Does this sound correct?
Thanks,
John
Re: minOccurs and nillable

Anne,
Yes, I came to the conclusion there was a difference, but I added both
purely to try and persuade Axis to handle the error.
I think Axis is ignoring the minOccurs="0", despite the fact I can see it
being set up in the source code generated:
elemField = new org.apache.axis.description.ElementDesc();
elemField.setFieldName("requestCategoryCode");
elemField.setXmlName(new javax.xml.namespace.QName("http://www.caps-solutions.co.uk/schema/uniform/72b/servicerequest/sr/srtypes","RequestCategoryCode"));
elemField.setXmlType(new javax.xml.namespace.QName("http://www.caps-solutions.co.uk/schema/uniform/72b/common/uniformtypes", "CNCODE_CodeValue"));
elemField.setMinOccurs(0);
elemField.setNillable(true);
Can this really be an Axis bug? I thought this would be fairly heavily tested?

Re: minOccurs and nillable
Posted by Anne Thomas Manes <at...@gmail.com>.
John,
There's a difference between missing and null. If the element had a
null value, then the element would be there, and it would say
<requestCategoryCode nil="true"/>.
If the schema says minOccurs="0", then this message is valid.
It appears that Axis is not properly handling minOccurs="0".

Re: minOccurs and nillable
Posted by Dennis Sosnoski <dm...@sosnoski.com>.
The XML instance document you supplied doesn't match the WSDL schema, so
Axis is correct in rejecting it. You should just have minOccurs="0"
added to the schema for the element. There's no reason to add
nillable="true", since just leaving the element out is the cleaner approach.
How did the third party generate their schema? It's very sloppy that
they built this incorrectly, since the schema is supposed to be the
contract for the XML representation.
