我想从我的Ksoap客户端向我的web服务发送一个复杂的对象。这是我的班级类别的对象。该代码基于本教程的示例：
http://seesharpgears.blogspot.de/2010/10/ksoap-android-web-service-tutorial-with.html
webservice正在运行，WSDL文件显示了category对象。但是，如果我将一个类别对象发送到我的soap webservice，则会出现以下错误：
[ERROR]尝试调用服务方法时发生异常 getCategoryObject org.apache.axis2.AxisFault：未知类型 {http://ws.chathura.com}类别Logcat显示以下内容：06-12 11：08：57.576：W / System.err（777）：SoapFault - faultcode： 'soapenv：服务器'faultstring：'未知类型 {http://ws.chathura.com}类别'faultactor：'null'详细信息： org.kxml2.kdom.Node@4054a528
这是我在Tomcat 7上运行的Java Webservice：
package com.chathura.ws;
import java.util.Vector;
public class HelloWorldWS
{
public Category getCategoryObject(Category obj)
{
Category C1 = new Category();
C1.setCategoryId(1);
C1.setDescription("server desc");
C1.setName("server Name");
System.out.println(obj.getCategoryId());
return C1;
}
}
这是我在WebServer上的类别类：
package com.chathura.ws;
public class Category {
private int CategoryId;
private String Name;
private String Description;
/**
* @return the categoryId
*/
public int getCategoryId() {
return CategoryId;
}
/**
* @param categoryId the categoryId to set
*/
public void setCategoryId(int categoryId) {
CategoryId = categoryId;
}
/**
* @return the name
*/
public String getName() {
return Name;
}
/**
* @param name the name to set
*/
public void setName(String name) {
Name = name;
}
/**
* @return the description
*/
public String getDescription() {
return Description;
}
/**
* @param description the description to set
*/
public void setDescription(String description) {
Description = description;
}
}
这是WSDL文件：
This XML file does not appear to have any style information associated with it. The document tree is shown below.

这是我的Android-Testing-App：
package de.bachelor.marcel;
import java.util.Vector;

try
{

SoapObject response = (SoapObject)envelope.getResponse();

tv.setText("CategoryId: " +C.CategoryId + " Name: " + C.Name + " Description " + C.Description);
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
这是Android客户端的类别类：
package de.bachelor.marcel;
import java.util.Hashtable;
import org.ksoap2.serialization.KvmSerializable;
import org.ksoap2.serialization.PropertyInfo;
public class Category implements KvmSerializable
{
public int CategoryId;
public String Description;
public String Name;
public Category(){}
public Category(int categoryId, String description, String name)
{
CategoryId = categoryId;
Name = name;
Description = description;
}
@Override
public Object getProperty(int arg0)
{
switch(arg0)
{
case 0:
return CategoryId;
case 1:
return Description;
case 2:
return Name;
}
return null;
}
@Override
public int getPropertyCount()
{
return 3;
}
@Override
public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2)
{
switch(arg0)
{
case 0:
arg2.type = PropertyInfo.INTEGER_CLASS;
arg2.name = "CategoryId";
break;
case 1:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "Description";
break;
case 2:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "Name";
break;
default:break;
}
}
@Override
public void setProperty(int arg0, Object arg1)
{
switch(arg0)
{
case 0:
CategoryId = Integer.parseInt(arg1.toString());
break;
case 1:
Description = arg1.toString();
break;
case 2:
Name = arg1.toString();
break;
default:
break;
}
}
}
答案 0 :(得分：0)
尝试使用
private static final String NAMESPACE = "http://ws.chathura.com/xsd";
并将getter和setter添加到客户端的Category类中。
答案 1 :(得分：0)
好的，我已经尝试过你的提示，现在我非常接近解决方案：
我发现，我需要2个名称空间（一个用于接收，一个用于发送）
所以我做了以下更改：
private static final String NAMESPACE = "http://ws.chathura.com";
private static final String NAMESPACE2 = "http://ws.chathura.com/xsd";
和此：
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
...
...
envelope.addMapping(NAMESPACE2, "Category",new Category().getClass());
现在我的Web服务收到我的对象类别，但是不传输Category（CategoryID）中的第一个属性，LogCat显示以下异常：
06-13 09:59:17.459: W/System.err(647): java.lang.RuntimeException: Unknown Property: categoryId

我在没有CategoryID的情况下第二次测试了它，但是Description是未知属性： - （
有什么问题？
修改 的
我认为异常是因为envelope.addMapping中的命名空间不同。我该怎么办，只能使用一个命名空间？
