服务器端程序:
package com.kavon.array;

import com.kavon.array.*;

public class ArrayTest{

public String[] getArray(){
String[] result = {"111111111","2222222222","33333333333"};
System.out.println("************return1");
return result;
}

public Message[] getMultiMessages(){
Message[] ms = new Message[2];
ms[0].setContent("111111111");
ms[0].setFrom("1111111111");
ms[0].setTo("1111111");
ms[0].setPriority(1);

ms[1].setContent("222222222");
ms[1].setFrom("222222222222");
ms[1].setTo("22222222222");
ms[1].setPriority(2);
System.out.println("************return2");
return ms;
}

public Message getSingleMessage(){
Message ms = new Message();
ms.setContent("3333333333");
ms.setFrom("33333333333333");
ms.setTo("33333333333333333");
ms.setPriority(3);

System.out.println("************return3");
return ms;
}
}
客户端程序:
package com.kavon.array;

import com.kavon.array.*;

public class Main{
public static void main(String[] args) throws Exception{
ArrayTestService arrayTestService = new ArrayTestServiceLocator();

ArrayTest_PortType arrayTest_PortType = arrayTestService.getArrayTest();
String[] mes = arrayTest_PortType.getArray();
for(int i = 0; i < mes.length; i++){
System.out.println(mes);
}

Message ms1 = arrayTest_PortType.getSingleMessage();
System.out.println("***************");
System.out.println(ms1.getContent());
System.out.println(ms1.getFrom());
System.out.println(ms1.getTo());
System.out.println(ms1.getPriority());
System.out.println("***************");

Message[] ms = arrayTest_PortType.getMultiMessages();
for(int i = 0; i < ms.length; i++){
System.out.println("***************");
System.out.println(ms.getContent());
System.out.println(ms.getFrom());
System.out.println(ms.getTo());
System.out.println(ms.getPriority());
System.out.println("***************");
}
}
}

前两个方法都调用成功,调用第三个方法时抛出异常
输出结果如下:
111111111
2222222222
33333333333
***************
3333333333
33333333333333
33333333333333333

请有经验者提供各种错误的可能,如果有确切的答案是再好不过了!
