ClassCastException while working with Lists
Hi,
I've created a new service using the following WSDL file and the java2wsdl
tool of cxf:
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions name="HelloWorld" targetNamespace="http://www.tum.de/test"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:tns="http://www.tum.de/test"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
<wsdl:types>
<xsd:schema targetNamespace="http://www.tum.de/test">
<xsd:complexType name="CtMessage">
<xsd:sequence>
<xsd:element name="x" type="xsd:int" />
<xsd:element name="y" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
<xsd:simpleType name="CtItems">
<xsd:list itemType="xsd:integer" />
</xsd:simpleType>
<xsd:element name="Message" type="tns:CtMessage" />
<xsd:element name="ItemCount" type="xsd:int" />
<xsd:element name="Items" type="tns:CtItems" />
</xsd:schema>
</wsdl:types>
<wsdl:message name="SayHelloResponse">
<wsdl:part name="parameter" element="tns:Items">
</wsdl:part>
</wsdl:message>
<wsdl:message name="SayHelloRequest">
<wsdl:part name="parameter" element="tns:Message">
</wsdl:part>
</wsdl:message>
<wsdl:portType name="HelloServiceInterface">
<wsdl:operation name="sayTest">
<wsdl:input message="tns:SayHelloRequest">
</wsdl:input>
<wsdl:output message="tns:SayHelloResponse">
</wsdl:output>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="SayHelloHTTP" type="tns:HelloServiceInterface">
<soap:binding style="document"
transport="http://schemas.xmlsoap.org/soap/http" />
<wsdl:operation name="sayTest">
<wsdl:input>
<soap:body use="literal" />
</wsdl:input>
<wsdl:output>
<soap:body use="literal" />
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="HelloService">
<wsdl:port name="HelloEndpoint" binding="tns:SayHelloHTTP">
<soap:address location="http://localhost:8080/services/TEST.asmx" />
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
The service implementation looks like this:
@WebService(endpointInterface = "de.tum.test.HelloServiceInterface",
serviceName = "HelloTest")
public class Implementation implements HelloServiceInterface {
@Override
public BigInteger[] sayTest(CtMessage parameter) {
System.out.println("Say Test");
return new BigInteger[] {};
}
}
Now if i call the sayTest method i get the following error:
org.apache.cxf.interceptor.Fault: Marshalling Error: [Ljava.math.BigInteger;

Hi,
Thanks for your reply Dan!
I'm using Apache Axis 2.2.10. It seems like the error has something to do
with the following part of the WSDL file:
<xsd:simpleType name="CtItems">
<xsd:list itemType="xsd:integer" />
</xsd:simpleType>
The generated Java code uses BigInteger[] and seems fine but unfortunately
does not work. Now I am using a different approach like this (just want to
transfer a list of integers):
<xsd:complexeType name="CtItems">
<xsd:sequence>
<xsd:element name="value" type="xsd:integer" maxOccurs="unbound"
minOccurs="0" />
</xsd:sequence>
</xsd:complexeType>
I can send you a fully working test case in form of a HelloWorld program but
it will take until monday.

You don't mention what version of CXF.
I just used the latest stuff and it seems to work fine. I did a wsdl2java -
all on the wsdl which did create that interface. I started the server, ran
the client, and got the empty BigInteger[] back.
Can you package up a fully non-working test case?
