hello everyone
I solved this problem
i add this code
//check user is login
String chk_login=(String)context.getServletContext().getAttribute(loginBean.getUsername().toLowerCase());
if("is_login".equals(chk_login))
loginBean.addError("actionError", "please do not login again ");
return "LoginRetry";
}else
context.getServletContext().setAttribute(loginBean.getUsername().toLowerCase(),"is_login");
}
now one user can be login once

There is a SessionListener which uses the com.concursive.connect.cms.portal.utils.Tracker for recording which user is logged in. When the user logs out or the session expires, the Tracker removes the user. You can query the Tracker with ((Tracker) context.getAttribute(Constants.USER_SESSION_TRACKER)).getUserList()
The benefit is that you now have a handle to the user's TrackerElement and sessionId.
Perhaps that can be useful.
