類型{http://www.w3.org/2001/XMLSchema}xml被引用但未定義

我在我的GWT服務器端使用AXIS 1.4來訪問SOAP。類型{http://www.w3.org/2001/XMLSchema}xml被引用但未定義

這裏是我的代碼：

String result = ""; 
QName servQN = new QName("XYZService"); 
Service service = new Service(wsdlLocation, servQN); 
Call call = (Call) service.createCall(); 

call.setOperationName("call"); 
call.setTargetEndpointAddress(endpointURL); 

result += (String) call.invoke(new Object[] { "LOGIN", arr });

那麼，這裏的WSDL文件我已經創建了：

<?xml version ="1.0" encoding ="UTF-8" ?> 
<definitions name="XYZ" 
targetNamespace="http://xxx.yyyyy.com/xxxserv/soap/main.wdsl" 
xmlns="http://schemas.xmlsoap.org/wsdl/" 
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" 
xmlns:tns="http://xxx.yyyyy.com/xxxserv/soap/main.wdsl" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 

<message name="getRequest"> 
    <part name="action" type="xsd:string"/> 
    <part name="params" type="xsd:xml"/> 
</message> 
<message name="getResponse"> 
    <part name="Result" type="xsd:xml"/> 
</message> 

<portType name="XYZPortType"> 
    <operation name="get"> 
    <input message="tns:getRequest"/> 
    <output message="tns:getResponse"/> 
    </operation> 
</portType> 

<binding name="XYZBinding" type="tns:XYZPortType"> 
    <soap:binding style="rpc" 
    transport="http://schemas.xmlsoap.org/soap/http"/> 
    <operation name="get"> 
    <soap:operation soapAction="urn:localhost-main#get"/> 
    <input> 
     <soap:body use="encoded" namespace="urn:localhost-main" 
     encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> 
    </input> 
    <output> 
     <soap:body use="encoded" namespace="urn:localhost-main" 
     encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> 
    </output> 
    </operation> 
</binding> 

<service name="XYZService"> 
    <port name="XYZPort" binding="tns:XYZBinding"> 
    <soap:address location="http://xxx.yyyyy.com/xxxserv/soap/server.php"/> 
    </port> 
</service>

當我在開發模式運行這個，我有此錯誤：

javax.xml.rpc.ServiceException: Error processing WSDL document: 
java.io.IOException: Type {http://www.w3.org/2001/XMLSchema}xml is referenced but not defined.

我在wsdl文件中做了什麼錯誤？請幫忙。
