axis客户端调用服务器端方法,返回对象数组(web service求助)
我在网上找了个公开的web service wsdl地址为:http://www.fundxy.com/fundxy/Common/FundxyService.asmx?WSDL
客户端用java编写
web service公开一方法为GetNewFundValue , 是接收三个整形参数(FundType,SortType,AscFlag),然后返回一个对象数组,对象为FundValue
我在客户端进行了FundValue对象自定义序列化,写了个javabean
我在客户端的axis代码是:
public class returnFundValue {
public static void main(String[] args) {
try {
Integer i = new Integer(1);
Integer j = new Integer(0);
Integer z = new Integer(0);
String endpoint="http://www.fundxy.com/fundxy/Common/FundxyService.asmx";
Service service = new Service();
Call call = (Call)service.createCall();
//注册对象
QName qn=new QName("http://www.fundxy.com/fundxy/common/fundxyservice", "FundValue");
call.registerTypeMapping(FundValue.class, qn,
new org.apache.axis.encoding.ser.
BeanSerializerFactory(FundValue.class, qn),
new org.apache.axis.encoding.ser.
BeanDeserializerFactory(FundValue.class, qn));
//注册对象数组
QName qname=new QName("http://www.fundxy.com/fundxy/common/fundxyservice","ArrayOfFundValue");
call.registerTypeMapping(FundValue[].class,qname,
new org.apache.axis.encoding.ser.BeanSerializerFactory(FundValue[].class,qname),
new org.apache.axis.encoding.ser.BeanDeserializerFactory(FundValue[].class,qname));
call.setTargetEndpointAddress(new java.net.URL(endpoint));
call.setOperationName(new QName("http://www.fundxy.com/fundxy/common/fundxyservice","GetNewFundValue"));
//添加参数:
call.addParameter("FundType",new QName("http://www.w3.org/2001/XMLSchema","int"),javax.xml.rpc.ParameterMode.IN);
call.addParameter("SortType",new QName("http://www.w3.org/2001/XMLSchema","int"),javax.xml.rpc.ParameterMode.IN);
call.addParameter("AscFlag",new QName("http://www.w3.org/2001/XMLSchema","int"),javax.xml.rpc.ParameterMode.IN);
//call.setReturnType(org.apache.axis.encoding.XMLType.SOAP_ARRAY);
//call.setReturnType(new QName("http://www.fundxy.com/fundxy/common/fundxyservice","GetNewFundValue"),FundValue[].class);
call.setReturnType(qname);
call.setUseSOAPAction(true);
call.setSOAPActionURI("http://www.fundxy.com/fundxy/common/fundxyservice/GetNewFundValue");
FundValue[] k= (FundValue[])call.invoke(new Object[]{i,j,z});
System.out.println( "result is " + k[1].getFundID());
}
catch (Exception e) {System.err.println(e.toString()); }
}
}
但是执行的时候就报下面的错误:
org.xml.sax.SAXException: Unable to create JavaBean of type [LFundValue;. Missi
ng default constructor? Error was: java.lang.InstantiationException: [LFundValu
e;.

能看出问题吗?
