Missing type in generated WSDL part definition when using int[] arrays with
RPC/Literal encoding
------------------------------------------------------------------------------------------------
Key: CXF-2005
URL: https://issues.apache.org/jira/browse/CXF-2005
Project: CXF
Issue Type: Bug
Affects Versions: 2.1.3
Environment: java version "1.6.0_11", apache-cxf-2.1.3 (with asm-2.2.3)
Reporter: Pierre Post
Priority: Minor
CXF seems to generate an incorrect WSDL when using operations with int[] array
parameters in web services using the RPC/Literal encoding. The following code
@WebService(name="MathService",
targetNamespace="http://test.backoffice.ciss.lu/service";)
@SOAPBinding(style=SOAPBinding.Style.RPC, use=SOAPBinding.Use.LITERAL)
public interface MathService {
@WebMethod(operationName="ConvertToString")
@WebResult(name="stringNumbers")
public String[] convertToString(@WebParam(name="intNumbers") int[] numbers);
}
generates the WSDL code (extract):
<wsdl:types>
<xs:schema attributeFormDefault="unqualified"
elementFormDefault="unqualified"
targetNamespace="http://jaxb.dev.java.net/array";
xmlns="http://jaxb.dev.java.net/array";
xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:complexType final="#all" name="stringArray">
<xs:sequence>
<xs:element maxOccurs="unbounded" minOccurs="0" name="item"
nillable="true" type="xs:string"></xs:element>
</xs:sequence>
</xs:complexType>
</xs:schema>
</wsdl:types>
<wsdl:message name="ConvertToString">
<wsdl:part name="intNumbers">
</wsdl:part>
</wsdl:message>
<wsdl:message name="ConvertToStringResponse">
<wsdl:part name="stringNumbers" type="ns1:stringArray">
</wsdl:part>
</wsdl:message>
As you can see, the type information is missing in the first <wsdl:part> tag.
The incorrect WSDL obviously produces errors, e.g. when generating the client
using the wsdl2java tool:
Loading FrontEnd jaxws ...
Loading DataBinding jaxb ...
wsdl2java -client -verbose
http://localhost:8080/CISS_BackOfficeTemplate/services/MathService?wsdl
wsdl2java - Apache CXF 2.1.3

The error does not occur when using the (default) Document/Literal encoding or
when using Integer[] arrays or List<Integer>. It is possible that the error
exists with other primitive types (long, double, etc.) but I haven't tested
them.
