Tapestry and XFire
Posted by Jim O'Callaghan <jc...@yahoo.co.uk>.
I'm currently using Tapestry for some business services and the presentation
tier of an application, but also have some related Web Services exposed
using XFire - currently XFire is reusing some of the POJOs I'm using as
service providers within Tapestry, by exposing them also as Spring beans.
Is there a way to get XFire to hook up directly with Tapestry, to avoid the
doubling up of configuration details (Hibernate settings, beans) for Spring?
It feels like I'm losing some of the handier features of Tapestry (minimal
configuration) because of the XFire integration.
Many thanks,
Jim.

Injecting the Request service would also work and it's the recommended
choice.

for the help! I did get to know, better!

Every Tapestry service (including Request) is wrapped by a proxy. When the
service is per thread, this proxy invokes the methods in the correct
object for that thread. It is a little bit strange at first, but it works.

There's no such thing as a per request session. Just @Inject Request and
get the session. It'll work.

Thiago,
Thanks for the reply. As u said, i did use sessions. But my problem, how am
i to access it? I mean, if i use RequestGlobals, i get per request session.
And, if i use Request service also, i get the same thing! How am i access
it? (Actually thats wat i tired to mean by non-threaded stuff, sorry!)

Some points:
1) Tapestry is a servlet filter, not a servlet.
2) There isn't a non-threaded version of HttpServletRequest, as it is
created for every request received.
3) As far as I know, it's not possible to count the number of concurrent
users without using the session, as HTTP is a stateless protocol. You'll
need to count open sessions. To do that, you'll need a service to hold the
number of open sesions and an HttpSessionListener.
I hope I gave you some pointers.
