Description:
axis-SNAPSHOT.jar as of Jan 30 2004 produces the following exception. A current cvs version of Mar 21 2004 produces the same exceptions. I just don't want to revert my whole installation to cvs. The position where the exception is risen differs slightly. For your convenience I have included the code snippets, where the exception is risen.

ResponderSOAPBindingStub was created by WSDL2Java. The parameters of the registerTypeMapping call are:
_call.registerTypeMapping(class java.lang.Object,
{http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties}>QueryResourcePropertiesResponse, null, class org.apache.axis.encoding.ser.SimpleDeserializerFactory, false)
(just printed with System.out.println)
looking at ResponderSOAPBindingStub._initOperationDesc1() this code is generated
by WSDL2Java (current CVS version):
oper = new org.apache.axis.description.OperationDesc();
oper.setName("QueryResourceProperties");
oper.addParameter(new
javax.xml.namespace.QName("http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties",
"QueryResourcePropertiesRequest"), new javax.xml.namespace.QName("http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties",
">QueryResourcePropertiesRequest"),
com.ibm.www.xmlns.stdwip.web_services.WS_ResourceProperties._QueryResourcePropertiesRequest.class,
org.apache.axis.description.ParameterDesc.IN, false, false);
oper.setReturnType(new
javax.xml.namespace.QName("http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties",
">QueryResourcePropertiesResponse"));
oper.setReturnClass(java.lang.Object.class);
oper.setReturnQName(new
javax.xml.namespace.QName("http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties",
"QueryResourcePropertiesResponse"));
oper.setStyle(org.apache.axis.enum.Style.DOCUMENT);
oper.setUse(org.apache.axis.enum.Use.ENCODED);
_operations[4] = oper;
this differs from the code that is generated by WSDL2Java (Version 1.1):
oper = new org.apache.axis.description.OperationDesc();
oper.setName("QueryResourceProperties");
oper.addParameter(new
javax.xml.namespace.QName("http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties",
"QueryResourcePropertiesRequest"), new
javax.xml.namespace.QName("http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties",
">QueryResourcePropertiesRequest"),
com.ibm.www.xmlns.stdwip.web_services.WS_ResourceProperties._QueryResourcePropertiesRequest.class,
org.apache.axis.description.ParameterDesc.IN, false, false);
oper.setReturnType(new
javax.xml.namespace.QName("http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties",
">QueryResourcePropertiesResponse"));
oper.setReturnClass(com.ibm.www.xmlns.stdwip.web_services.WS_ResourceProperties._QueryResourcePropertiesResponse.class);
oper.setReturnQName(new
javax.xml.namespace.QName("http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties",
"QueryResourcePropertiesResponse"));
oper.setStyle(org.apache.axis.enum.Style.DOCUMENT);
oper.setUse(org.apache.axis.enum.Use.ENCODED);
_operations[4] = oper;
And later in the constructor ResponderSOAPBindingStub(javax.xml.rpc.Service service)
Version 1.2 cvs:
qName = new
javax.xml.namespace.QName("http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties",
">QueryResourcePropertiesResponse");
cachedSerQNames.add(qName);
cls = java.lang.Object.class;
cachedSerClasses.add(cls);
cachedSerFactories.add(null);
cachedDeserFactories.add(simpledf);
Version 1.1:
qName = new
javax.xml.namespace.QName("http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties",
">QueryResourcePropertiesResponse");
cachedSerQNames.add(qName);
cls =
com.ibm.www.xmlns.stdwip.web_services.WS_ResourceProperties._QueryResourcePropertiesResponse.class;
cachedSerClasses.add(cls);
cachedSerFactories.add(beansf);
cachedDeserFactories.add(beandf);
This is what the imported schema looks like:
<wsdl:definitions name="WS-ResourceProperties"
xmlns="http://schemas.xmlsoap.org/wsdl/" ...>
...
<xsd:element name="QueryResourcePropertiesResponse" >
<xsd:complexType>
<xsd:complexContent mixed="true">
<xsd:restriction base="xsd:anyType">
<xsd:sequence>
<xsd:any processContents="lax"
minOccurs="1" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:restriction>
</xsd:complexContent>
</xsd:complexType>
</xsd:element>
...
<wsdl:message name="QueryResourcePropertiesResponse">
<wsdl:part name="QueryResourcePropertiesResponse"
element="wsrp:QueryResourcePropertiesResponse" />
</wsdl:message>
...
<wsdl:portType name="QueryResourceProperties">
<wsdl:operation name="QueryResourceProperties">
<wsdl:input name="QueryResourcePropertiesRequest"
message="wsrp:QueryResourcePropertiesRequest" />
<wsdl:output name="QueryResourcePropertiesResponse"
message="wsrp:QueryResourcePropertiesResponse" />
<wsdl:fault name="ResourceUnknownFault"
message="wsrp:ResourceUnknownFault" />
<wsdl:fault name="InvalidResourcePropertyQNameFault"
message="wsrp:InvalidResourcePropertyQNameFault" />
<wsdl:fault name="UnknownQueryExpressionDialectFault"
message="wsrp:UnknownQueryExpressionDialectFault" />
<wsdl:fault name="InvalidQueryExpressionFault"
message="wsrp:InvalidQueryExpressionFault" />
<wsdl:fault name="QueryEvaluationErrorFault"
message="wsrp:QueryEvaluationErrorFault" />
</wsdl:operation>
</wsdl:portType>
And these are the the locations that raise the exception:
_call.registerTypeMapping(class java.lang.Object,
{http://www.ibm.com/xmlns/stdwip/web-services/WS-ResourceProperties}>QueryResourcePropertiesResponse,
null, class org.apache.axis.encoding.ser.SimpleDeserializerFactory, false)
org.apache.axis.client.Call.registerTypeMapping(Call.java:2227):
public void registerTypeMapping(Class javaType,
QName xmlType,
Class sfClass,
Class dfClass,
boolean force) {
// Instantiate the factory using introspection.
SerializerFactory sf =
BaseSerializerFactory.createFactory(sfClass, javaType, xmlType); // <- here
DeserializerFactory df =
BaseDeserializerFactory.createFactory(dfClass,
javaType,
xmlType);
if (sf != null || df != null) {
registerTypeMapping(javaType, xmlType, sf, df, force);
}
}
org.apache.axis.encoding.ser.BaseSerializerFactory.createFactory(BaseSerializerFactory.java:270):
public static SerializerFactory createFactory(Class factory,
Class javaType,
QName xmlType) {
SerializerFactory sf = null;
try {
Method method =
factory.getMethod("create", CLASS_QNAME_CLASS); // <- here
sf = (SerializerFactory)
method.invoke(null,
new Object[] {javaType, xmlType});
FWIW: The following patch "fixes" the problem but I don't know how many new ones are created as I don't understand the code ;-)
