1. Schema:
<!-- Define global elements -->
<xs:element name="gBooleanNillable" type="xs:boolean" nillable="true"/>
<!-- Refer global elements -->
<xs:complexType name="MyOperationRequest_Type">
<xs:sequence>
<xs:element ref="gBooleanNillable"/>
</xs:sequence>
</xs:complexType>
2. wsdl2java testing
With AXIS1.2 RC1 wsdl2java, a java.lang.Boolean class will be generated
.
org.apache.axis.wsdl.symbolTable.DefinedElement
QName:
{http://service.wellsfargo.com/provider/ecpr/prototype/myOperation/2007/
}gBooleanNillable
name: java.lang.Boolean
isReferenced? true
Class: org.apache.axis.wsdl.symbolTable.DefinedElement
Base?: true
Undefined?: false
isSimpleType? false
Node: [xs:element: null]
Dims:
RefType:
QName: {http://schemas.xmlsoap.org/soap/encoding/}boolean
name: java.lang.Boolean
isReferenced? true
Class: org.apache.axis.wsdl.symbolTable.BaseType
Base?: true
Undefined?: false
isSimpleType? false
Node: null
Dims:
RefType: null
With AXIS1.4 wsdl2java, NO java.lang.Boolean class will be generated.
org.apache.axis.wsdl.symbolTable.DefinedElement
QName:
{http://service.wellsfargo.com/provider/ecpr/prototype/myOperation/2007/
}gBooleanNillable
name: boolean
isReferenced? true
Class: org.apache.axis.wsdl.symbolTable.DefinedElement
Base?: true
Undefined?: false
isSimpleType? false
Node: [xs:element: null]
Dims:
isOnlyLiteralReferenced: false
RefType:
QName: {http://www.w3.org/2001/XMLSchema}boolean
name: boolean
isReferenced? true
Class: org.apache.axis.wsdl.symbolTable.BaseType
Base?: true
Undefined?: false
isSimpleType? false
Node: null
Dims:
isOnlyLiteralReferenced: false
RefType: null
3. The problem is that AXIS 1.4 wsdljava does not create Boolean wrapper
class for the element with nillable=true. This does not follow JAX-RPC
1.1 standard.
4. What I found.
I found that AXIS 1.4 did not retrieve the attribute of ref element. In
fact,
I found following code were commented out in the method
getTypeQNameFromAttr of org.apache.axis.wsdl.symbolTable.utils.java
(AXIS 1.4)
// An alternate qname is returned if nillable
// if (typeAttrName.equals("type")) {
// if (JavaUtils.isTrueExplicitly(getAttribute(node,
"nillable"))) {
// qName = getNillableQName(qName);
// }
// }
Based on my understand, this code is needed.
5. What I did
I uncommented out above code and put back the method
"getNillableQName(qName)" (from AXIS 1.2).
Testing proved it fixed my problem
/**
* getNillableQName returns the QName to use if the nillable=true
* attribute is used.
* For example, in JAX-RPC:
* The QName "xsd:int" maps to a java int.
* However if an element with a type="xsd:int" also has the
* "nillable=true" attribute, the type should be an Integer (not
an int).
* So in these circumstances, this routine is called with xsd:int
to
* get a suitable qname (soapenc:int) which maps to Integer.
* @param qName QName
*/
public static QName getNillableQName(QName qName) {
QName rc = qName;
if (Constants.isSchemaXSD(rc.getNamespaceURI())) {
String localName = rc.getLocalPart();
if (localName.equals("int") ||
localName.equals("long") ||
localName.equals("short") ||
localName.equals("float") ||
localName.equals("double") ||
localName.equals("boolean") ||
localName.equals("byte"))
{
rc = findQName(Constants.URI_DEFAULT_SOAP_ENC,
qName.getLocalPart());
}
else if (localName.equals("base64Binary"))
{
rc = findQName(Constants.URI_DEFAULT_SOAP_ENC,
"base64");
} else if (localName.equals("hexBinary")) {
rc = findQName(Constants.URI_DEFAULT_SCHEMA_XSD,
"hexBinary");
}
}
return rc;
}
6. My question
Does anyone know the reason we commentted above code ?
Since I do not fully understand wsdl2java changes for AXIS 1.4 yet, I
will really appreciate that anyone points out the issue of doing that.
Thanks in advance.
