What are the current choices of mature Clojure web frameworks? I am looking for some kind of feature matrix telling me what the popular frameworks support and to what extent, including: Response templating (response written in Clojure or in some other markup - e.g. like JSP with Tiles) HTTP sessions REST with automatic mapping of URLs into action-functions and params HTML forms (params available as map, error handling, validation) Application flow (known from Java frameworks - request handlers return action identifiers which are eventually handled by renderers) Michał Marczyk Perhaps my answer

I'm a little confused about how to do something that I thought would be quite simple. I have a simple app written using Flask . It looks something like this: from flask import Flask app = Flask(__name__) def _run_on_start(a_string): print "doing something important with %s" % a_string @app.route('/') def root(): return 'hello world' if __name__ == "__main__": if len(sys.argv) < 2: raise Exception("Must provide domain for application execution.") else: DOM = sys.argv[1] _run_on_start("%s" % DOM) app.run(debug=True) What I'm finding is that my terminal is outputting the print statements in _run

I've pretty much tried every Python web framework that exists, and it took me a long time to realize there wasn't a silver bullet framework, each had its own advantages and disadvantages. I started out with Snakelets and heartily enjoyed being able to control almost everything at a lower level without much fuss, but then I discovered TurboGears and I have been using it (1.x) ever since. Tools like Catwalk and the web console are invaluable to me. But with TurboGears 2 coming out which brings WSGI support, and after reading up on the religious debates between the Django and WSGI camps, I'm

The two Haskell web frameworks in the news recently are Yesod (at 0.8) and Snap (at 0.4). It's quite obvious that Yesod currently supports a lot more features than Snap. However, I can't stand the syntax Yesod uses for its HTML, CSS and Javascript. So, I'd like to understand what I'd be missing if I went with Snap instead. For example, doesn't look like database support is there. How about sessions? Other features? mightybyte Full disclosure: I'm one of the lead developers of Snap. First of all, let's talk about what Snap is. Right now the Snap team maintains five different projects on hackage

I would like to see how Web Developers avoid the double submission problem. So basically my understanding of the problem is as follows: Double submission occurs when an impatient user submits a form multiple times, causing issues. This problem can be fixed by JavaScript (specifically jQuery scripts) that disable the submit button once the form has been submitted - a weakness of this is if clients have JavaScript disabled. There is also server side methods of detection. So my questions are: How do people overcome double submission? What is a real life example of a problem caused by double

Which is the best framework for Java? I'm looking for something similar to Symfony for php and Ruby-On-Rails for Ruby? I even don't know if anything such exists for Java or not. There are many great web frameworks for java, but if your looking for something that is similar to Rails, look at Grails . It uses Groovy , which is dynamic language, but uses the Java VM. Check out their quick start to determine if it's what you want. Georgy Bolyuba Take a look at Spring. I think it will do anything Ruby-On-Rails can do (you can also add Hibernate for ORM). i suggest you to check out the playframework
