[Lift] Re: lift nearly inaccessible for newby
Not ment as a offence but you are in way over your head! A couple of things: 1. You say you are a non-programmer but I assume you do understand Scala? Or else it is pointless to use Lift as it is based on the Scala language and relies heavily on its features. Knowledge of Java is also a plus cause some of the libs are not available in Scala but only in Java and it is better to know Java in order to understand the libraries. 2. You do have experience with websites? Complex web applications? If not then I suggest you start by doing a simple static page for your design to get to know the technics you are trying to use or you get yourself a programmer/webdesinger to do it for you. If you are not willing to learn about the technical details you will get in big trouble later on and I mean trouble that can actually cost you money. 3. If the above points do not seem valid for you then please get professional help 4. If you are not scared by the above points and you are willing to invest then I suggest getting some example code and starting to disect that. Take a look at http://github.com/tjweir/pocketchangeapp which is a complete demo app in lift and take a look at http://github.com/tjweir/liftbook for a liftbook that is available freely.

[Lift] Re: lift nearly inaccessible for newby
I didn't want to discourage you I just wanted to be honest and please do come back with any question you have as we learn by asking. But at the same time as was said in this thread already take the time to expriment and use the resources that are there (google and the like) to come up with the answers yourself. As you do this you will start to understand stuff more and more and things will get easier. With the professional help I simply ment that if you have a short time to market then you will not get happy with experimenting and you might consider paying someone (a professional) or finding someone who will do it for you since the other way is going to cost you a lot of time. About what David Pollak said: I think he does a great job designing and maintaining lift but I still think without knowing Scala it is virtually impossible to come to grips with Lift no matter how easy it is to set it up. Learning a programming language with no programming background is quite a job, and in my opinion well worth it, but a long term commitment is required. About the comment with Rails... not too sure if Rails or Lift is easier or they are the same. I have experience with Rails and I love the Ruby syntax which I think is a tad better then Scalas so I find Rails still a tad easier but that is because of lack of experience with Lift. If I wouldn't take Lift serious I wouldn't be here and spend my time learning it. I just do not want you to think that you can simply grab lift and understand it immediately. One more thing about the documentation of Lift. The biggest problem I had when starting was that there is no easy link to a workable Lift demo except for the maven archetype and that is just not complex enough for learning purposes. Thank god to github and the likes the applications to checkout are getting more. Still I think it would be great if the Lift website had a download for an application like the Java PetStore or the like for beginners to study. Befor anyone thinks I'm starting a rant here this is just a suggestion and if I can find the time besides all the other pet projects of mine ;) I might just start a demo app. Regards Stefan 2009/10/6 koveen > > Stefan, > > thanks for your reply. :) > > to anwser your questions: I have no experience with Java and I only > made some very simple static websites, years ago.

[Lift] Re: Getting error -Access denied after deploying on Apps Engine
Looks like some part of your program is creating threads or trying to modify them which is prohibited by AppEngine as far as I know. Please correct me if I'm wrong.

[Lift] Re: Turning off garbage collection
Why do you consider it nessecary to turn off garbage collecting if there is nothing to garabage collect? Turning of garabage collecting has to be done on the jvm level as far as I know. So you would have to turn it off for the whole servlet container. Musk 2009/9/21 Charles F.
