Session transfer between Tapestry and non-Tapestry app

[Jeevan Bihari <je...@yahoo.com>]

  Let's say I have two web apps running on one application server. One of the apps is a Tapestry
one while the other is using a different framework. If I transfer the session from the
non-Tapestry app to the Tapestry app, is there a way for me to retrieve information from the
passed session in the latter ?

Thanks,
Jeevan

Yes.

This is easily done. Extend the HomeService with your
own custom class then override the service method.

Extract the data from the session and dump them in
your own Visit object implementation.

A snap shot of what I did is below:

----------------snip-------------------

    public boolean service(IEngineServiceView engine,
IRequestCycle cycle, ResponseOutputStream output)
            throws RequestCycleException,
ServletException, IOException {
        Visit visit = (Visit)(engine.getVisit(cycle));

        if(visit==null) {
            logger.debug(">>>> Visit is NOT NULL -
something is really wrong!!! <<<<");
        }
        HttpSession session =
(cycle.getRequestContext()).getSession();
        HttpServletRequest request =
(cycle.getRequestContext()).getRequest();
        
        // here you would extract your session
variables and populate
        // you custom Visit object.
        
        
        return super.service(engine, cycle, output);
    }

--------------end snip--------------------------

Don't for get to specify your custom HomeService in
your application spec.

Cheers,
Stav.

Sure can.  The IRequestContext is a facade for the usual servlet API 
stuff - session, request, response etc. so if you put stuff in the 
session (or request?) you can grab it from your Tapestry app anywhere 
you have an IRequestContext.  We use this (in reverse) to pass info 
from our Tapestry app to a colocated servlet from a 3rd party 
framework.  HTH
