apache axis 如何序列化一个参数，比如序列化FILE等，在部署文件里和客户端程序怎么完成。求救啊！！！！！

Question

这是我的部署文件，请大家看下我错在哪里？？
<?xml version="1.0" encoding="UTF-8"?>
<deployment name="defaultClientConfig"
    xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"
    xmlns:handler="http://xml.apache.org/axis/wsdd/providers/handler"
    xmlns="http://xml.apache.org/axis/wsdd/">
    <service name="urn:xmlToDB" provider="java:RPC">
        <namespace>http://localhost:8083/axis/services/xmlToDB</namespace>
        <parameter name="className" value="com.borland.samples.xml.XMLDBMS.XMLDBMS_Test"/>
        <parameter name="allowedMethods" value="xmlToDB"/>
        <typeMapping
        xmlns:ns="http://localhost:8083/axis/services/xmlToDB"
        qname="ns:File"
        type="java:java.io.File"
        serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
        deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
        encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
      />
      </service>
</deployment>这是客户断程序：
package com.borland.samples.xml.XMLDBMS;import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
import java.io.File;
import org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory;
import org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory;
import javax.xml.rpc.ServiceFactory;
public class Client {
  public Client() {
  }  public static void main(String[] args) {
    try {
      String endPoint = "http://localhost:8083/axis/services/xmlToDB";
      Service service = new Service();
      Call call = (Call) service.createCall();
      call.setTargetEndpointAddress(new java.net.URL(endPoint));
      call.setOperationName(new QName("urn:xmlToDB", "xmlToDB"));
      File source = new File("D:/jczhouWork/XMLDBMSBeans/InputFile.xml");
      QName qnameAttachment = new QName("urn:xmlToDB", "ns:File");
      call.registerTypeMapping(source.getClass(), //Add serializer for attachment.
                               qnameAttachment,
                               JAFDataHandlerSerializerFactory.class,
                               JAFDataHandlerDeserializerFactory.class);      call.invoke(new Object[] {source});
    }
    catch (Exception ex) {
      ex.printStackTrace();
    }
  }
}
出错主要信息是CLASSCASTEXCEPTION

Answer 2

我本人没有直接将文件作为webservice提供给外部，只是提供过字节数组，如果你的文件不大的话，可以考虑一下。就是先将文件内容读成byte[]数组，然后提供给外部。这样客户端不需要做特殊处理，只需要将接收到的数据装换成byte[]数组就可以了。没有任何的特殊性。

Answer 3

File并不是一个可以序列化的类，你必须将这个File的内容全部读入到字节数组中然后再将这个字节数组作为WebService的调用参数如果这个文件太大，上述方法则不可行，也就说明你可能需要分开几组调用以减少字节数组大小等（这个需要你自己控制，并不存在直接的方法可用）

Answer 4

我是要将客户端文件（很小）作为参数传递到Service的方法。参数类型是：File。我怎么将File序列化。
谢谢您！bison_java

Answer 5

谢谢ChDw(米)！
可是我看了很多例子，其中有序列化自己写的类，然后再声明typeMapping！

看看
http://ws.apache.org/axis/java/user-guide.html#XMLJavaDataMappingInAxis里面都说了
