Hi,
Tapestry in Action covers managing state. Start with 2.2.4 "Examinging
the Visit Object" and re-read that section. I think chapter 7 or so
may also have more information.
I must have been blind. Years ago I was involved in WebObjects
application development - so the concepts are familiar (Visit alias
Session).
But Tapestry in Action will only cover how to maintain state in
Tapestry - it does not cover clustering directly because that's
outside the realm of the book.
Do you know of any real world clustering solution (Resin, Tomcat)? I
will read their docs.
Once you are properly maintaining state in a single application server
instance - then you can explore clustering. Each application server
will have its capabilities and configuration setup steps.
Also you may need additional hardware such as an F5 load-balancer.
And as Richard Hensley pointed out - you need to determine whether you
want to do this for scalability or reliability.
Scalability is the main issue. I guess reliability is more in good
programming practice domain - backed by some hardware setup only helps
of course.

Hi, a little late. Getting to our administrator was a time consuming task.
Now, he says we are using LVS (Linux Virtual Server) to balance requests
(all sessionless). I guess the same would be true for sessionless
Tapestry web app. What if sessions become requirement for the new web app?
An article about deploying Tapestry app in multiserver environment would
be great. I read Howard's article
http://www.theserverside.com/articles/article.tss?l=TSSTapestry, but it
focuses on translating JSPs to Tapestry.
I have a book "Tapestry in Action", but it doesn't cover this topic. Did
I miss it? Anyway, links to material appreciated!

Borut,
Do the current JSP application run in a clustered environment? There should
be very little difference between your JSP application deployment and a
Tapestry application deployment across a cluster.
Can you be a little more specific about the issues you are encountering or
anticipate?
Richard

Subject: Load balancing
Hello,
can someone point me to a resource where I can learn how to deploy
tapestry application on several linux machines to handle [per day]:
* 150.000 unique visitors
* 1.500.000 pages
This holds true for our current JSP app, so the pages number might not
be informative.
Is such high volume traffic site at all possible with Tapestry?

Borut Bolčina
