访K3Cloud的webapi出错

我在本地搭建了一个K3Cloud，开启了webservice，我现在想做一个测试，通过api，得到物料的数据。我用java开发，引入了金蝶的jar包。做了一个Test，
@Test
public void testsearch() throws Exception {
K3CloudApiClient k3CloudApiClient = new K3CloudApiClient([i]KingdeeURL[/i]);
String dbid = "5a2e23934b7cc5";[i]//帐套ID
[/i][i] [/i]String username="administrator";[i]//用户名
[/i][i] [/i]String password = "888888";[i]//密码
[/i][i] [/i]String formId="BD_MATERIAL";[i]//物料的表单Id
[/i][i] [/i]Boolean result = k3CloudApiClient.login(dbid,username,password,2052);
if (result){
Map map = new HashMap();
map.put("FormId",formId);[i]//表单Id
[/i][i] [/i]map.put("TopRowCount", "0");
map.put("Limit", "200");[i]//每页的允许数，最大不超过2000
[/i][i] [/i]map.put("StartRow", "0");
map.put("FieldKeys", "");

String json = JSON.[i]toJSONString[/i](map).replaceAll("\"","\\\\\"");
[i]logger[/i].info(json);
List> sResult = k3CloudApiClient.executeBillQuery(json);
[i]logger[/i].info("result="+ JSON.[i]toJSONString[/i](sResult));

}else {
[i]logger[/i].info("登录失败！");
}

}

运行后就报错：
