java WebService 数组

Question

在wsdl里这样定义的：
...
<xsd:complexType name="ArrayOf_xsd_string">
    <xsd:sequence>
    <xsd:element minOccurs="0" maxOccurs="unbounded" name="item" type="xsd:string"/>
    </xsd:sequence>
</xsd:complexType><wsdl:message name="arrayRequest">
    <wsdl:part name="item" type="ArrayOf_xsd_string"/>
</wsdl:message><wsdl:message name="arrayResponse">
    <wsdl:part name="arrayResponse" type="xsd:string"/>
</wsdl:message><wsdl:portType name="arrayPT">
    <wsdl:operation name="arrayOP">
      <wsdl:input message="arrayRequest"/>
      <wsdl:output message="arrayResponse"/>
    </wsdl:operation>
</wsdl:portType>
...现在想用java写一个客户端，调用这个WebService,可是那个数组的输入参数该怎么传进去，总是出错，求助！！
