Accessing named session attributes in XSP?

[Derek Hohls <DH...@csir.co.za>]

I know I am missing something *very* obvious, but
I have "end of day" stare here, and cannot figure what
mistake I am making.
 
I am using the Database Authenticator to process a
login - the user ID is stored in a session attribute called
"userrname"  The auth.xml used looks like:

<auth-descriptor>
  <connection>myDB</connection>
  <table name="user">
    <select dbcol="UserName" request-param="username"
to-session="username"/>
    <select dbcol="UserPassword" request-param="userpass" />
  </table>
</auth-descriptor>

This process seems to be working, as I can now get 
access to the protected part of the pipeline: ie.
 
<map:match type="sessionstate" pattern="*">
   <map:parameter name="attribute-name" value="username"/>
<!-- all this is accessible after login -->
</map:match> 

However, when I try and use the username attribute in
an XSP file, I just get a "null" returned - here's the snippet
from the file:

<xsp:page
  language="java"
  xmlns:xsp="http://apache.org/xsp"
  xmlns:xsp-session="http://apache.org/xsp/request/2.0"
>

<!-- Page-level logic -->
<page>

  <xsp:logic>  
    //session
    String sUserName = <xsp-session:get-attribute name="username"
as="string"/>; 
  </xsp:logic>

  <element><xsp:expr>sUserName</xsp:expr></element>

</page>


The <element> now contains "null" (wihtout the ")


Any idea how to get the username out into the XSP??

Thanks
Derek

AW: Accessing named session attributes in XSP?

[Marco Rolappe <m_...@web.de>]

hi derek,

could you tell me please how the XSP is accessed? the problem might be that
your XSP is dealing with a different session (XSPs default to creating a new
session).
