方法一：采用Portal的Puma API

Java代碼

1. Context?ctx?=? new ?InitialContext(); ??
2. PortletServiceHome?pumaServiceHome?=?(PortletServiceHome)?ctx.lookup( "portletservice/com.ibm.portal.um.portletservice.PumaHome" );??????????????? ??
3. PumaHome?puma_home?=? null ;?????????????? ??
4. if ?(pumaServiceHome?!=? null ){ ??
5. ???????? ??
6. ????puma_home?=?(PumaHome)?pumaServiceHome.getPortletService(PumaHome. class ); ??
7. } ??
8. PumaProfile?pp?=?puma_home.getProfile(); ??
9. User?user?=?pp.getCurrentUser(); ??
10. String?uid?=?pp.getIdentifier(user);???

    Context ctx = new InitialContext();
PortletServiceHome pumaServiceHome = (PortletServiceHome) ctx.lookup("portletservice/com.ibm.portal.um.portletservice.PumaHome");				
PumaHome puma_home = null;				
if (pumaServiceHome != null){
		
	puma_home = (PumaHome) pumaServiceHome.getPortletService(PumaHome.class);
}
PumaProfile pp = puma_home.getProfile();
User user = pp.getCurrentUser();
String uid = pp.getIdentifier(user); 
  

?

方法二：采用傳統的Request方式

Java代碼

1. request.getUserPrincipal().getName();??或 request.getRemoteUser();

    request.getUserPrincipal().getName();
  

    ?request.getRemoteUser();
  

?

方法三：采用Taglib方式

Java代碼

1. <%@?taglib?uri= "http://www.ibm.com/xmlns/prod/websphere/portal/v6.0/portal-fmt" ?prefix= "portal-fmt" ?%>? ??
2. <portal-fmt:user?attribute= "cn" />??
