有关Web Service传递复杂类型的问题

Web Service中有一些API是接收复杂类型的,我是这样的调用的,但出现了异常.代码和异常如下,希望达人指点.
不知我哪里出错?

客户端代码:

String wsdlUrl = "http://localhost:8080/axis/services/PersonIdServ?wsdl";

String nameSpaceUri = "urn:PersonIdServ";
Service service = new Service();

Call call = (Call) service.createCall();

QName ariQn = new QName(nameSpaceUri, "BiArithmetic");

call.registerTypeMapping(BiArithmetic.class, ariQn,

new BeanSerializerFactory(BiArithmetic.class, ariQn),

new BeanDeserializerFactory(BiArithmetic.class, ariQn)

);

try {

call.setTargetEndpointAddress(new URL(wsdlUrl));

call.setOperationName(new QName(nameSpaceUri,
"createBiArithmetic"));

call.addParameter("arg1", ariQn, ParameterMode.IN);
call.setReturnType(XMLType.AXIS_VOID);
BiArithmetic biAri = new BiArithmetic ("1234567", 1);
biAri.setAriData(byteArrayOut.toByteArray());
biAri.setAriName("test");
biAri.setAriSuffix("ari");
biAri.setBaseInd("N");
biAri.setPrimaryInd("Y");
biAri.setFetchLen("9999");
biAri.setUsualInd("Y");
Object obj = call.invoke(new Object[] { biAri});
if (obj != null)
System.out.println(obj.toString());

} catch (Exception e) {
e.printStackTrace();

}

布置代码:
<service name="PersonIdServ" provider="java:RPC">

<parameter name="className" value="com.ak.bi.serv.PersonIdServ"/>

<parameter name="allowedMethods" value="*"/>

<beanMapping qname="myNS:BiArithmetic" xmlns:myNS="urn:BiArithmetic" languageSpecificType="java:com.ak.bi.BiArithmetic"/>

</service>

异常:
log4j:WARN No appenders could be found for logger (org.apache.axis.i18n.ProjectResourceBundle).

很明显是客户端出错了,BiArithmetic.class里有一个Field是int类型,其他为String类型.
Ps:如果我传递的是基本类型的话是没问题的.
期待达人指点.

我用的WS引擎是Axis...

能不能看看你的wsdl

这是其中一部分...
太长不能贴全部

你觉得问题出现在哪?
org.xml.sax.SAXException: No object was found for class type int
这样的异常在网上也找不到相应的解决办法...
难道要到Axis官方去发Email?

[hmsuccess]

其实wsdl中的复杂类型在被解析是生成了java类，包括类的方法和属性，所以对复杂类型的
处理其实就是对某一个java类的处理，不知道我这么说你能不能理解

[CPPvip]

不是理不理解的问题啊
我要解决问题...

为什么我能接收复杂类型返回值却不能作为方法参数传递呢,显然应该不是定义的问题.
不知在这方面有经验的达人吗

[hmsuccess]

不能将复杂类型作为参数传递？你是不是这个意思

[healer_kx]

很多都用Axis啊。我觉得WebService不是让你传递复杂对象用的，那是RMI的事情。

总的来说，我觉得不是很可行。

[hmsuccess]

但是他应该在服务器端的绑定实现上，如xxxBindingImpl.java在实现中如果参数是一个在wsdl中定义的
complexType的话，那么这个参数应该是一个对象，而且大部分情况下需要序列化

[CPPvip]

对,WSDL中已经定义了序列化了,不然也不会返回复杂类型了,对吧...

做为参数传递也是可以的,只不过出现了上面的异常,当我的复杂类型中有INT时,如果是String的话是可以的.

[hmsuccess]

我想问的是int是复杂类型吗，我以前写过这样的wsdl
如：

<xsd:complexType name="Item">
<xsd:all>
<xsd:element name="product_id" type="xsd:string"/>
<xsd:element name="product_name" type="xsd:string"/>
<xsd:element name="unit_price" type="xsd:float"/>
<xsd:element name="quantity" type="xsd:int"/>
<xsd:element name="total_price" type="xsd:float"/>
<xsd:element name="description" type="xsd:string"/>
</xsd:all>
</xsd:complexType>

生成的类为Item.java

public class Item  implements java.io.Serializable {
    private java.lang.String product_id;

    private java.lang.String product_name;

    private float unit_price;

    private int quantity;

    private float total_price;

    private java.lang.String description;

    public Item() {
    }

    public Item(
           java.lang.String product_id,
           java.lang.String product_name,
           float unit_price,
           int quantity,
           float total_price,
           java.lang.String description) {
           this.product_id = product_id;
           this.product_name = product_name;
           this.unit_price = unit_price;
           this.quantity = quantity;
           this.total_price = total_price;
           this.description = description;
    }//其中的一部分

[dracularking]

String有对象 而int没有对应的对象吧

[CPPvip]

哎,怎么会这样呢?

再搞不好就不想传复杂类型了...

谢谢以上各位热心的网友...

[hmsuccess]

是啊，int是基本数据类型，在xml中是内嵌的
