HttpSessionFacade

[Dominic Reynolds]

Hi,
  I have a question regarding the use of HttpSessionFacade. It appears that many
 instances of this object can wrap the same *real* session. These objects are th
en recycled by tomcat (unbinding the facade from the real session). This recycli
ng happens prior to the session being invalidated which can cause troubles on se
rvlet objects which use the session. What are the rules that govern when a facade is 
recycled?
 Previous mailing-list threads recommend to use the context to store servlet app
lication data but I'm confused as to why the HttpSession object provides an inte
rface to set/get data if not for the application to store data that should be pe
rsisted accross requests but used within a single session.

thanks,
dominic.

error in HttpSessionFacade when working with Apache/Tomcat 3.2

[Hanusch, Hartwig]

Hi there,

does anybody know why a servlet works fine with tomcat only (port 8080) 
but when using apache/tomcat via jk_mod (or old jserv) the servlet throws
an error like that:

java.lang.NullPointerException:
at org.apache.tomcat.facade.
HttpSessionFacade.getId(HttpSessionFacade.java:114)
...

the calling code looks that way:

session is hash of sessions

for (Iterator i = sessions.iterator(); i.hasNext(); )
{
HttpSession theHttpSession = (HttpSession) i.next();
String sid = theHttpSession.getId();< problem,
calling HttpSessionFacade 
if (loginObj.hasContentSessionRelatedBlaSession(sid) != true)
{
tmpVec.add(theHttpSession);
}
}

Could that be a configuration error? Doesnt seems like?! Any ideas?
When looking at the HttpSession the stored session in memory seem to mix up!

Happy to here from anybody
