tomcat＋Axis
客户端 使用org.apache.axis.client.Call 的对象得到服务器端返回的object。这个obj
ect是一个字符串数组，在客户端如何把object还原为String[]的数据类型？
使用下面方法
Object resp=call.invoke(new Object[] {new Integer(id)});
result=(String[])JavaUtils.convert(resp,String[].class);
报错java.lang.ArrayStoreException
        at org.apache.axis.utils.JavaUtils.convert(JavaUtils.java:432)
        at ArrayClient.main(ArrayClient.java:43)
直接强制转换也要错。
客户端程序如下：
import org.apache.axis.AxisFault;
import org.apache.axis.client.*;
import org.apache.axis.utils.JavaUtils;

import org.apache.axis.encoding.ser.ArraySerializerFactory;
import org.apache.axis.encoding.ser.ArrayDeserializerFactory;

import org.apache.axis.encoding.XMLType;

import javax.xml.rpc.ParameterMode;
import javax.xml.namespace.QName;

import java.io.*;

public class ArrayClient{
    public static void main(String[] args)throws Exception{
        String url="http://localhost:8080/axis/servlet/AxisServlet";
        String id=null;
        try{
            BufferedReader reader=new BufferedReader(
                                       new InputStreamReader(System.in));
            System.out.println("Enter id:");
            id=reader.readLine();
        }catch(IOException e){
            e.printStackTrace();
        }
        Service service=new Service();
        Call call=(Call) service.createCall();
        
        QName qn=new QName("http://soapinterop.org/xsd","ArrayOfstring");
        call.registerTypeMapping(String[][].class,qn,
                                 new ArraySerializerFactory(),
                                 new ArrayDeserializerFactory());
        String result[]={""};
        
        try{
            call.setTargetEndpointAddress(new java.net.URL(url));
            call.setOperationName(new QName("AddressService","getArray"));
            call.addParameter("id",XMLType.XSD_INT,ParameterMode.IN);
            call.setReturnType(qn);
               Object resp=call.invoke(new Object[] {new Integer(id)});
            //if (JavaUtils.isConvertable(resp,String[].class))
               result=(String[])JavaUtils.convert(resp,String[].class);
            //else System.out.println("can not convert");
            
        }catch(Exception e){
            //System.out.println(fault.toString());
            e.printStackTrace();
        }
        System.out.println("Address of "+id);
        
        for(int i=0;i<result.length;i++)
            System.out.println("\t"+result[i]);
    }
}
服务器端：
import java.io.*;

public class AddressService{
    private int[] id={111,222,333};
    private String[][] addressBook={{"Street 11","London","UK","34534"},
                                    {"Lane 4","New York","USA","53457"},
                                    {"Lane 5","LA","USA","67635"}};
    public String[] getArray(int id){
        System.out.println(id);                                    
        for(int i=0;i<addressBook.length;i++){                              

            if(this.id[i]==id){
                return addressBook[i];
            }
        }
        
        String error[]={"id not found!"};
        return error;
    }
    public static void main(String arg[]){
        AddressService as=new AddressService();
        String num=null;
        try{
            BufferedReader br=new BufferedReader(new InputStreamReader(System.
in));
            System.out.println("Enter id:");            
            num=br.readLine();
        }catch(IOException e){e.printStackTrace();}
        String[] ret={""};
        int n=(new Integer(num)).intValue();
        ret=as.getArray(n);
        for(int i=0;i<ret.length;i++) System.out.println(ret[i]);
    }
              
}
