lift

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. Matt I'm currently working on a series of projects in lift, so I'll give my personal experiences. Its a very capable framework - and I find it makes lighter work of application development than the equivalent in rails or django. However, you will need a reasonable understanding of scala in order to get started on sophisticated

I heard a lot of good things about Scala and the Lift Web framework recently, especially from Foursquare's guys hence, I might use this technology in my next projects. Are any of you Scala/Lift Developers? What have your experiences been for developing on this platform and what are its advantages over Ruby On Rails or Python/Django? Do you see it as a viable technology and "something to keep an eye on" for the next couple of years? Is it worth it? Share your experiences on the Scala/Lift Platform. I'm currently doing most of my things in Scala right now. (I should mention that I think that

I have a date input box in my lift application, and I want to check that a user-entered date is in correct format: dd/mm/yyyy . How can I write a regex check for this in scala? I've looked at pattern matching examples - but that seems over-complicated. PS: I don't have to use regex, any other alternatives are welcome! SimpleDateFormat is ugly and (more disturbingly) non-thread-safe. If you try to simultaneously use the same instance in 2 or more threads then expect things to blow up in a most unpleasant fashion. JodaTime is far nicer: import org.joda.time.format._ val fmt = DateTimeFormat

I wanted to start a new web application project and I am confused between two frameworks that is GWT(Java) or Lift(Scala). So I want your opinion which one I choose? Both are good according to my project requirement. So on the basis of frameworks comparison please tell me which is good? I have found GWT to be an extremely effective technology for the client side, and use a combination of Java and Scala on the server-side. GWT is attractive because it allows you to write your web application in Java from front to back; you code in Java; and you debug your program in Eclipse, seamlessly stepping

Given the various advantages of the Scala language I have decided to write my next web-application in Scala. However, should I be using Wicket or Lift? I am familiar with Wicket, and like it quite a bit, but know very little about Lift. Is learning Lift worth the effort in this context? In order words, how does Lift compare to Wicket? Given that the web-app will be in Scala, could using Lift make my life as a developer easier? If you like Wicket, you should stick with what you know & like. Wicket is a fine web framework and doing Scala & Wicket is very nice because you can use Scala's traits

I'm developing on the standard Lift platform (maven and jetty). I'm repeatedly (once every couple of days) getting this: Exception in thread "7048009@qtp-3179125-12" java.lang.OutOfMemoryError: PermGen space 2009-09-15 19:41:38.629::WARN: handle failed java.lang.OutOfMemoryError: PermGen space This is in my dev environment. It's not a problem because I can keep restarting the server. In deployment I'm not having these problems so it's not a real issue. I'm just curious. I don't know too much about the JVM. I think I'm correct in thinking that permanent generation memory is for things like

Is it possible in Lift web framework to create forms (and links) that react via AJAX, but also work without Javascript support? If so, how? When I build the form using <lift:form.ajax> , the form's action is set to javascript:// so that it no longer submits without JS. If I build the form without explicit AJAX support, I don't know how to insert the AJAX functionality. I suppose I could build a RESTful interface (we'll have to build that anyway) and write custom Javascript to submit the form through that. I would like to avoid code duplication, though: if it is possible to handle all three

I'm trying to find the 'right' actor implementation. I realized there is a bunch of them and it's a bit confusing to pick one. Personally I'm especially interested in remote actors, but I guess a complete overview would be helpful to many others. This is a pretty general question, so feel free to answer just for the implementation you know about. I know about the following Scala Actor implementations (SAI). Please add the missing ones.
