  • Push alerts to notification tray app in Java

    - by Rich Anderson
    Hi - how do I push server alerts to tray apps in java without using xmpp or other heavy protocols? Do you recommend a way to accomplish this? I was planning to write an app which uses URLConnection on a server equipped with Comet but I doubt if that would work as the client requires a JS to be invoked and URLConnection is not a browser.. What is the best way to push instead of using a proprietary client-server approach?

  • Should I use Java for a custom Swing component designed for a clojure app?

    - by nansen
    I want a simple timeline component (like in video editing software) for a clojure/seesaw app and I am wondering if it is a good approach to implement this directly with clojure and seesaw or if I should write it in java and make my clojure wrapper around it. Or more generally: is a functional programming language optimal for writing UI widgets? I cannot imagine doing that without a lot of state involved. And wasn't OO invented for UI-development in the first place?

    - by jmccartie
    Trying to write a deployment script, working on a repo in a different path. The "git-dir" flag seems to work fine for most commands, but not for submodule work. Am I missing a path directive?

  • How to learn open source library API without good documentation

    - by Turtle
    I am recently working on the open source library openmetaverse which is designed as an open source substitution of second life viewer. I think the problem is that it is not well documented. Sometimes, I just misunderstand the API when I really used it in real program which is very annoying because sometimes you need to write many code. But how to make sure the API just acts the way you expected? So what is your way to learn new API without good documentation?

  • Problem creating a webpage in OOP pattern?

    - by Starx
    I want to develop a website in OOP pattern, but I am stuck in a point whether I need to inherit from multiple classes. For example I have a main class "index" this class has several methods which need to inherited from other classes and I have created seperate classes for it like class "banner", class "content", class "footer" Not only this but class "content" has several methods to be inherited from other classes like class "gallery", class "news", etc I found out that multiple inheritance is not allowed, and using interface I cannot write codes in its methods, so how can i achieve a solution for this problem.

  • CakePHP 1.3.0 Cookie value not encrypting

    - by Jason McCreary
    I noticed in Firefox when viewing the cookies that the values I am saving are not encrypted. The CakePHP Book states that values are encrypted by default on write(). I can't seem to find any gotchas in the doc Anyone else experience this problem? I am sure I am missing something.. Would it matter that the value being set is a integer?
