.net与java webservice传输对象数组的问题

[敛我半世癫狂]

java平台那边调用.net提供的webservice接口，参数为对象数组。但是调用后，可识别我的对象，但数组长度一直为0

webservice

    /// <summary>
    /// Summary description for DepartmentService
    /// </summary>
    [WebService(Namespace = "...")]
    [SoapDocumentService(RoutingStyle = SoapServiceRoutingStyle.RequestElement)]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class DepartmentService : System.Web.Services.WebService
    {

        [WebMethod]
        public void saveDepartmentDataFromSap(SapDepartmentData[] List)

对象

namespace DepartmentProxy
{
    [XmlType(Namespace = "...")]
    public class SapDepartmentData
