RE: Redirect JSP

Matt,

Basically I want to have a Login.jsp like this:
<%
HttpSession  mySession  = request.getSession(false);
// get user_id
String suserID = request.getParameter( "username" );
// put values on the session to send them on screen
mySession.setAttribute("username",suserID);
//mySession.setAttribute("username","Reiher");
//redirect to screen
response.sendRedirect("LoginScreen.jsp?username=" + 
mySession.getAttribute("username"));
%>

This sits in a location protected by Basic Auth. using a validation list. 
I was hoping that request.getParameter("username") would grab the username 
entered in the validation list dialog box and I could use it to pass them 
on to the URL. Does that make sense??
Sorry, a little green with java

RE: [WEB400] Redirect JSP






I'm not following what you're doing (I understand what you want to do).
I did a similar thing not too long ago. What I have is:

- A JSP for user name/password entry
- A servlet to process the form. If it passed validation, I do a
redirect to a URL otherwise, I do a forward back to the JSP page to show
error messages.

If you're doing all of this in the JSP, you should have access to a
response object.

One error that I see now that I've taken another look at this is that
request.getRemoteUser() isn't going to return anything (you'll probably
get 'null' returned) unless you password protect the JSP (and servlet if
you're using one) using basic authentication which makes this redundant.

Sorry about that, it does look confusing now that you say that. However,

WEB is the host name, some genious decided to call it that. Basically I 
could take that URL and the value of request.getRemoteUser and go right
to 
the URL. I am doing something wrong though, because WS doesn't like the 
way I am doing it......

You either need to send them to a full URL with the host name (which
you're missing) or to a relative URL. Basically, the redirect URL has to
be something that you could put in a web page as a hyperlink.

Subject: [WEB400] Redirect JSP

I want to have a jsp page that I can use just for authenticating users
and 
then if valid redirect them to a URL built using the username they 
entered. Something like this
String redirectURL = "http://WEB/TEST/WFInvocation.do?inv=INV1&&USR="; + 
request.getRemoteUser;
response.sendRedirect(redirectURL);
Only thing I run into right now is that in WebSphere "request" is not 
known or valid. Or I am not doing it correctly. Any suggestions???
 
Thanks!
