The server did something wrong

java代码：

URL dispatchUrl = new URL(this.dispatchPath);

// 初始化contentService

ContentManagerService_ServiceLocator cmServiceLocator =

new ContentManagerService_ServiceLocator();

this.contentManagerService = cmServiceLocator.getcontentManagerService(dispatchUrl);

this.contentManagerService.logon(

buildXml4Logon(namespace,username, password),

new SearchPathSingleObject[] {}

);

// 生成passport字符串

SOAPHeaderElement headerElement = ((Stub) this.contentManagerService)

.getResponseHeader(

"http://developer.cognos.com/schemas/bibus/3/",

"biBusHeader"

);

执行到：this.contentManagerService.logon时报上述错误。是不是http://www.ibm.com/xmlns/prod/cognos/contentManagerService/201101/会有问题吗？但在网上找到资料都是这样写法。
