请教: SDK试验,报错faultString: CM-REQ-4342

本人新手, 试运行SDK下的AlertsUI.java
connection.connectToCognosServer();连接到服务器是报错
cmService.query(
     new SearchPathMultipleObject("/"),
     new PropEnum[] {},
     new Sort[] {},
     new QueryOptions());执行到这里时, 抛出异常java.rmi.RemoteException
具体内容如下:


AxisFault
faultCode: Client
faultSubcode:
faultString: CM-REQ-4342 An error occurred with the client.
faultActor:
faultNode:
faultDetail:
{http://developer.cognos.com/schemas/bibus/3/}exception:
