Found the following command which solves the problem for me:
mvn archetype:generate -DarchetypeCatalog=http://scala-tools.org/
Would still be great to know what went wrong.

Please show me a example.

I don't know how hard would it be to add this feature, so I don't know
if this is a reasonable request. This would make making JSON API
endpoints really easy for me and I hope for other people too.
This certainly sounds like a reasonable feature request, I will take a
deeper look at it.
Agreed - changes that modify lifts enviroment require restarting
jetty. It's not ideal perhaps, but it's with good reason.

How can assure that every time a comet page is loaded, it starts again
fresh? I.e. as if the page were being loaded for the first time?

Thanks Tim and Viktor.. Thats disappointing, I was hoping I wouldn't
have to restart the jetty server if when I added a new view.
Maybe there is a creative way around this? E.g. is there a way to get
a new view/page into lift without modifying Boot.scala?

Well this is not Lift's fault ... Lift application is initialized only
once as the servlet filter is. Running boot more then once per context
may lead to unexpected behaviors and in LiftRules we have a guard for
RuleSeq that they can not be changed after boot is executed.
You could however
Well render will be called for sure ... but if you build your comet
component to rely only with partial updates when updating coment's
real estate and don't call re-render then render should be called only
when page is loaded, meaning that you can reset any state there. ...
of course unless
Anyways, I was definitely screwed up ... forcing maven to actually do
what it was supposed to fixed my problem. Thanks for the pointer

Marius, I'm not trying to lay blame :)
I'm sure I'll get by, restarting jetty when pages are added.. I was
hoping for more though given what I'd read about JavaRebel and Lift
integration.

I have been looking for Web frameworks that will take advantage of an
Event Driven programming model.
Some Frameworks like Python's Zope and Grails manage to subscribe to
Model Events. E.g. one can subscribe to a notification message,
whenever a domain model gets changed, added, deleted, etc.
I have read that the Lift framework supports the CometActor model.
As far as I understand this is achieved by creating many threads out
of some thread pool, each of which handles one or more client socket
connection to a client.
My question is, what kind of approach Lift takes to handle access
Scala has a natural support for events notifications = Scala Actors.
It's a very natural fit for building event driven systems. In Lift
we're moving CometActors to LiftActors instead of Scala Actors due to
some memory consumption problems with current Scala actors
implementation which are
In my experience, the database engine itself does a pretty good job of
managing concurrent connections like this out of the box, which is
much of the reason why connection pooling is so effective.
Of course, thinks can be a bit interesting on the database side if you
want to get really obsessive

Of late i've been having several discussions with people about how

Specifically, how are people managing multiple apps in one install of
jetty? Or, alternatively, how are you embedded jetty so you have an
executable JAR?

override barField {

Hi Marius,
Thanks for your fast response. As an app developer, if I would like to
get notified from the persistence layer, that some changes to my
domain model have happened, how could I get such functionality with a
Scala actor? By subclassing the persistence class? Or is such
functionality
Just some more fuel for this debate:

Well the way I have it render is being called multiple times so I can
put initial code there. I have some code near the top of my Comet
class and thats the code I want to run every time I load the page.
Currently, it is only run the first time.

I put the line
println(dude)
in a Comet class write under the class declaration.
i.e.
class JoopComet extends CometActor with CometListenee {
println(INSIDE COMET CLASS)
When the class runs and all the activity is complete, I hit the back
button and that loads the JoopComet class again.
Viktor, you and I should not be up this late on a sunday! ;-)
You have to see this: http://blogs.webtide.com/janb/entry/jetty_runner
Im going to hash this together as a maven assembly; if it works, then
i'll write a blog and stuff it on the wiki... this could really make

If memory serves, the comet actor lives on in the session scope until
its either sent the ShutDown message explicitly, or it times out (you
can set the timeout).
Does that help?

Atsuhiko,
With the code exactly as you wrote it, how would you modify it to do
this?
Whenver the Comet Page gets loaded, it resets itself.

Maybe you could put a snppet on the page whose job is to reset the comet?

How about wrapping your CometActor page with the snippet?
