When redirecting from some_action.jsp to login_success.jsp the requestbuffer is cleared, causing the parameters to be lost.
What you should do is set the parameters in the HTTP session in some_action.jsp and read them back in login_success.jsp.
To transfer the values to non-Java applications, your best bet is to set them as HTTP request parameters or to include them in the HTTP headers.
