As a summary, you should be able to add the following lines and get
what you want:
<%@ page import="javax.servlet.http.HttpSession" %>
...
<%= session.getAttribute("returnBack").toString(); %>
The first line imports the class necessary to read the session attributes.
The second line prints the value of the "returnBack" session attribute.
Add the import with the other imports in login.jsp
Add the second line wherever you want to print the value.

Ok, here's what I see.
I modified the login.jsp to print the session attributes in a table
field. This is what I saw:
Attribute Name Class Name Value
returnBack class java.lang.String /arsys/forms/arsdev/User
arsys_login_name class java.lang.String
arsys_login_msg class java.lang.String
arsdev is the name of my remedy server. You should be able to go from
here, parse the values as you need to return what you want to see.
The returnBack session attribute stores to where the user will be
redirected.
Here is a diff of the login.jsp for the changes I made to see what was
out there:
