ALUI-Create Web Service - Remote Portlet Error 401:Unauthorized

Question

I have some problems during user ALUI(AquaLogic User Interaction 6.1).
I created a Web Service - Remote Portlet,then set value of Basic Authentication Settings is "User's Basic Authentication Information". When related remote server refer to tomcat5.5,the Web Service - Remote Portlet is fine to run,but not when the related remote server refer to weblogic9.2.
When value of Basic Authentication Settings is "Use Remote Server Basic Authentication Information", related remote server refer to weblogic9.2 or tomcate5.5, the portlet is fine.
error detail:
Error
sso Portlet cannot be displayed because the remote server returned an invalid HTTP response code.
We recommend:
• Refresh sso Portlet
• Accessing this portlet at a later time.
• Contacting your portal administrator if problems persist.
Detailed error information
• Response status: 401
• Response body:
Error 401--Unauthorized
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.2 401 Unauthorized
The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.46) containing a challenge applicable to the requested resource. The client MAY repeat the request with a suitable Authorization header field (section 14.8). If the request already included Authorization credentials, then the 401 response indicates that authorization has been refused for those credentials. If the 401 response contains the same challenge as the prior response, and the user agent has already attempted authentication at least once, then the user SHOULD be presented the entity that was given in the response, since that entity MAY include relevant diagnostic information. HTTP access authentication is explained in section 11.

How to configure remote server to accept authorization header?
I set value of Basic Authentication Settings is "User's Basic Authentication Information" because the Web Service - Remote Portlet need to get the portal's login user infomation.If the value is "Use Remote Server Basic Authentication Information",the application is fine to run.
The follow is the way to get login user infomation.
IPortletContext portletContext = PortletContextFactory.createPortletContext(request, response);
ICredentialProvider cProvider = portletContext.getCredentialProvider();
String username = cProvider.getUsername();
String password = cProvider.getPassword();
Do you have other way to authenticate users?
Thanks.
