WeService重复调用出现异常的问题

Question

由于WebService接口是按照分页来获取数据，所以当需要获取全部数据时，就需要循环获取多次！但是在循环调用的过程中，执行到302次时，就出现了异常：
异常信息如下：
[code="java"]AxisFault
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: java.lang.NullPointerException
faultActor:
faultNode:
faultDetail:
{http://xml.apache.org/axis/}hostname:WWW-C09C0AC6275

java.lang.NullPointerException

at com.peaksport.service.client.StockGoodsinfoClient.main(StockGoodsinfoClient.java:71)[/code]调用WebService客户端的代码如下：[code="java"]public void update2Goodsinfo(Integer count) {
DBManager.prepare4UpdateGoodsinfo();
Service service = new Service();
Call call;
try {
call = (Call) service.createCall();
call.setOperationName("getLJStockGoodsinfo");
URL url = new URL(SERVER_URL);
call.setTargetEndpointAddress(url);
if (count != 0) {
List bgs = null;
String result = null;
for (int i = 1; i <= count; i++) {
System.out.println(i);
if(i==302){
System.out.println("toggle");
}
result = (String) call.invoke(new Object[] { VERYFY_CODE,
new String("" + i), PAGESIZE });
bgs = JSONParser.parseGoodsJson2List(result);// 解析成List集合
DBManager.update2Goodsinfo(bgs);

            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}[/code]提示是在[code="java"]result = (String) call.invoke(new Object[] { VERYFY_CODE,
                        new String("" + i), PAGESIZE });[/code]出现的异常！

你这条数据有问题吧，应该是服务端查找这条数据时报错了
