map:generate -> servlet -> empty session problem

[Merico Raffaele <ra...@less.ch>]

Hi 

I'm using Cocoon 2.1.5.1 under Tomcat 4.0.4.
I have a servlet tixj.VE2000i does a login and starts a session.
When I try to invoke the servlet again to generate some XML data using the
following sitemap it always has an empty session.

<map:match pattern="**VersicherterSuchen.html">
 <map:generate src="{request:concat(scheme, '://', serverName, ':',
serverPort, '/ve2000ic/servlet/tixj.VE2000i?', queryString)}"/>
 <map:transform type="xslt"
src="xsl/xml2html/appl/VersicherterSuchen/VersicherterSuchen.xslt">
  <map:parameter name="global.host" value="{request:concat(scheme, '://',
serverName, ':', serverPort)}"/>
  <map:parameter name="global.contextPath" value="/ve2000ic/appl"/>
  <map:parameter name="global.lang" value="de"/>
 </map:transform>
 <map:serialize type="xhtml"/>
</map:match>

For your support many thanks in advance ... Raffaele

You should not access your servlet in that way is it starts a new 
external request (over http again, and with a new request object, so 
without session). The JSPGenerator (which is indeed a ServletGenerator 
as Unico stated somewhere in the Javadocs IIRC) might be the solution 
for you. You can of course also add the session info into the above URL 
string, but that's not the perfect solution IMO.
