Java调用asp.net webservice传值为null问题

[andyking_]

最近用asp.net写了一个webservice供Java调用，但是接收到Java方传过来的值总是null，而返回给Java方的值是可以收到的，在网上查了很多资料，有的说是namespaces的事，要在每个参数上都加上namespaces，但是怎么个加法，谁知道告诉我一下，给个例子看看，或者有更好的解决办法拿出来分享一下，谢谢！分数不够可以再加

可能是你命名空间问题

示例：

namespace TestDemo
{
    using System;
    using System.Data;
    using System.Web;
    using System.Collections;
    using System.Collections.Generic;
    using System.Web.Services;
    using System.Web.Services.Protocols;
    using System.ComponentModel;
    using System.Diagnostics;
    using System.Xml.Serialization;


    /// <remarks/>
    [System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.42")]
    [System.SerializableAttribute()]
    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://www.test.com")]
    public partial class MyClass
    {

        private string messageField;
        private string otherdataField;

        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(IsNullable = true)]
        public string message
        {
            get
            {
                return this.messageField;
            }
            set
            {
                this.messageField = value;
            }
        }


        /// <remarks/>
        [System.Xml.Serialization.XmlElementAttribute(IsNullable = true)]
        public string otherdata
        {
            get
            {
                return this.otherdataField;
            }
            set
            {
                this.otherdataField = value;
            }
        }
    }


    /// <remarks/>
    [System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.42")]
    [System.Web.Services.WebServiceAttribute(Namespace = "http://www.test.webservice.com")]
    [System.Web.Services.WebServiceBindingAttribute(Name = "TestHttpBinding", Namespace = "http://www.test.com")]
    [System.Web.Services.Protocols.SoapDocumentService(RoutingStyle = SoapServiceRoutingStyle.RequestElement)]
    public partial class TestService : System.Web.Services.WebService
    {
        /// <remarks/>
        [System.Web.Services.WebMethodAttribute()]
        [System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestNamespace = "http://www.test.com", ResponseNamespace = "http://www.test.com", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
        [return: System.Xml.Serialization.XmlElementAttribute("out", IsNullable = true)]
        public int testservice([System.Xml.Serialization.XmlElementAttribute(IsNullable = true)] MyClass in0)
        {
            if(in0 == null)
            {
                return 0;
            }
            else
            {
                return 1;
            }
        }
    }
}

你可以根据wsdl文件，用wsdl.exe生成webservice代理类
