Question

xfire客户端向服务器端传参数时，当参数是自定义的javabean时怎么出错呢？

public static void main(String[] args) {
TdLyqyCommodityInfo com = new TdLyqyCommodityInfo();
com.setInformation("XfireTest0");
Object[] results;
try {
Client client = new Client(new URL("http://192.168.0.207:8080/TravelInfoService/ws/Market?wsdl"));
//第一个测试------测试传入普通字符串，可以打印出结果
//results = client.invoke("sayHello", new Object[]{"tomcat"});
// 第二个测试-------测试传入一个自定义的类型TdLyqyCommodityInfo com对象 时就出错，
// results = client.invoke("saveOrUpdate", new Object[]{com});
// 打印上面两个测试的结果 ，
// System.out.println(results[0]);
//第三个测试-------这个是为了无参时，但返回值 是一个List<自定义对象 > 时，也是报错
results = client.invoke("getAllCommodity", new Object[]{});
//第三交测试的结果转换成List
List<TdLyqyCommodityInfo> list =(List<TdLyqyCommodityInfo>) results[0];
//输出第三个测试的结果
for(TdLyqyCommodityInfo temp : list){

System.out.println(temp.getAreaCode()+" "+temp.getInformation()+" "+temp.getKeyword());
}
} catch (Exception e) { e.printStackTrace();
}
}

第二次测试的错误：
