I want to know the technical reasons why the lift webframework has high performance and scalability? I know it uses scala, which has an actor library, but according to the install instructions it default configuration is with jetty. So does it use the actor library to scale?

I am just getting started with lift and I am now trying to change a normal form to an ajax form but the method processEntryAdd is never called. def addUser(xhtml : Group) : NodeSeq = { var firstName = "" var lastName = "" def processEntryAdd() { Log.info("processEntryAdd: " + firstName + ", " + lastName) } ...
I am using JsonResponse to send some JSON to the client. I would like to test that I am building the correct message for a given input, so it seemed natural to me to parse the resulting JSON and validate against a data structure rather than parsing a string by hand. Lift's JsObj produces a string which uses single quotes. This is vali...
Just wondering if anyone has experience with the three. I have used read through some RoR and used Django. They seem fairly easy to use. Is lift "easy" like these two are? I know easy is subjective and has no context here. I mean in a very high level and general sense. ...

Has anyone tried to do a scala/lift application using MVC instead of view-first? I know that you can create Controllers/views as: package test.test.test.view ...

I have been using Grails for the past few months and I really like it, specially GORM. However, I am getting interested into Scala's Lift. Therefore, I would like to know your opinion about which kind of web apps are better suited for which of those two frameworks or it is just a matter of taste, which framework to use? Finally, which o...
I'm learning Scala and lift at the same time and I got stuck on understanding the syntax used to inintialize the SiteMap in the Boot.scala: val entries = Menu(Loc("Home", "/", "Home")) :: Menu(Loc("Foo", "/badger", "Foo")) :: Menu(Loc("Directory Foo", "/something/foo", "Directory Foo")) :: Nil LiftRules.setSiteMap(Site...

I'm completely stumped. I'll give the background for the sake of completeness but I'm not sure if it will help or not. I'm running a Lift project on a standard Jetty set-up running one Lift instance. Mac OS X. I have a snippet which transforms the XML input, renders an image, saves it to disc under the webroot/images/ directory with a f...
Hi I'm having some trouble with Lift and URL rewriting. I've written a simple rewrite rule: LiftRules.rewrite.append { case RewriteRequest( ParsePath(List("user", userID), _, _, _), _, _) => { println(userID) RewriteResponse(List("viewUser"), Map("userID" -> urlDecode(userID))) } } So when I enter http://loca...

Can I get a simple example of a Lift form submission and processor? I've seen the Lift hello world, which was pretty trivial and didn't really give a flavor for how it works. I'm coming from a spring MVC background, but I have some FP experience. ...
I'm making a small issue management system in Lift to learn both Scala and Lift. I have a view that displays a single issue belonging to a project. Before I bind data to the view template, I want to check that I have all data required, so I want to specifically check that: A project ID param has been supplied A Project exists with the...
I have been working on a project and as I have just started on the webservice I found Lift has been released, so I am curious if there will be much more complication by using Lift over Jax-WS using JDK6. I am doing this with the Eclipse IDE, but I don't know if I will get much benefit from the IDE on this project. ...

It successfully downloads needed dependencies and everything works fine, however it does not download sources - I'd like to see how lift works from inside. Looks like it downloads de...
What I think would be useful for me (and hopefully for other SO readers and Scala fans) is: How to painlessly set up lift on linux (ubuntu) (apt-get install lift #does not work) Is there any free server where I can run lift and Scala? I have no experience with Java or maven or Eclipse. (but have some experience with functional progra...
