I'm trying to intercept the http calls which are generated during page loading. In other words, I would to realize a network traffic analyzer like the Firefox Firebug Net Panel.
Is it possible in Javafx?
Thanks.
Call URL.setURLStreamHandlerFactory
Read A new era for Java Protocol Handlers to understand the background for this.
Answer assumes you are using the standard WebView implementation or the java.net.URL class for networking and not some custom method.
A code sample for this would take me some time. The recommended approach is to follow the instructions provided in my answer. I'll put together a code sample in a few days if I have time and the question asker or nobody else has provided a sample.

Is there a Listener for the ending of playback of JavaFX AudioClip?
I don't see anything listed in the API. With a classic javax.sound.sampled.Clip, we can employ a LineListener.
I see that there is an isPlaying() method. But it would only be as accurate as the rate at which one monitors.
Looks like the answer is "No".
Thanks to #Slaw for having taken the time to provide this in a comment.
Hi and thank you for looking into this.
(Disclaimer: I have little-to-no technical background and would like to find the least complex solution. Ideally, only "connecting" different out-of-the-box components and no coding.)
HIGH-LEVEL PROBLEM:
I have trained a model for text classification using Google AutoML. I want to make this model available on a website, ie I want to enable visitors to enter their text and to receive the model's predicted class.
CONSIDERATIONS SO FAR: AutoML allows us to deploy the model via REST API and I understand that what I want are the API's PUT and GET function (right?). Ideally, I would use some form of plug-in or script to create an input field for the user which accepts the PUT and then delivers the GET.
Are you aware of any services for this? I'm also happy to host the website in an content management system like WordPress.
I'm very open regarding other approaches to solving my problem and highly appreciate any constructive input.
Many thanks!

EDIT Jan 10 There is another question related to this and a depo is shared which supposedly provided a solution. I'm not able to access the depo but the question might help you to understand my issue. Is there a way to use Googles AutoML with JavaScript?
EDIT Jan 16 I have learned that in order to provide the input to the model the POST function could be used instead of the PUT.
I was wondering if it is possible to use Julia to perform computations on a webpage in an automated way.
For example suppose we have a 3x3 html form in which we input some numbers. These form a square matrix A, and we can find its eigenvalues in Julia pretty straightforward. I would like to use Julia to make the computation and then return the results.
In my understanding (which is limited in this direction) I guess the process should be something like:
collect the data entered in the form
send the data to a machine which has Julia installed
run the Julia code with the given data and store the result
send the result back to the webpage and show it.
Do you think something like this is possible? (I've seen some stuff using HttpServer which allows computation with the browser, but I'm not sure this is the right thing to use) If yes, which are the things which I need to look into? Do you have any examples of such implementations of web calculations?
If you are using or can use Node.js, you can use node-julia. It has some limitations, but should work fine for this.
Coincidentally, I was already mostly done with putting together an example that does this. A rough mockup is available here, which uses express to serve the pages and plotly to display results (among other node modules).
Another option would be to write the server itself in Julia using Mux.jl and skip server-side javascript entirely.
Yes, it can be done with HttpServer.jl
It's pretty simple - you make a small script that starts your HttpServer, which now listens to the designated port. Part of configuring the web server is that you define some handlers (functions) that are invoked when certain events take place in your app's life cycle (new request, error, etc).
Here's a very simple official example:
https://github.com/JuliaWeb/HttpServer.jl/blob/master/examples/fibonacci.jl
However, things can get complex fast:
you already need to perform 2 actions:
a. render your HTML page where you take the user input (by default)
b. render the response page as a consequence of receiving a POST request
you'll need to extract the data payload coming through the form. Data sent via GET is easy to reach, data sent via POST not so much.
if you expose this to users you need to setup some failsafe measures to respawn your server script - otherwise it might just crash and exit.
if you open your script to the world you must make sure that it's not vulnerable to attacks - you don't want to empower a hacker to execute random Julia code on your server or access your DB.
So for basic usage on a small case, yes, HttpServer.jl should be enough.
If however you expect a bigger project, you can give Genie a try (https://github.com/essenciary/Genie.jl). It's still work in progress but it handles most of the low level work allowing developers to focus on the specific app logic, rather than on the transport layer (Genie's author here, btw).
If you get stuck there's GitHub issues and a Gitter channel.
Try Escher.jl.
This enables you to build up the web page in Julia.
i want to handle any download request coming from Webview. how it is possible ? the documentation https://developer.blackberry.com/native/reference/cascades/bb__cascades__webresourcerequestfilter.html and https://developer.blackberry.com/native/reference/cascades/bb__cascades__webdownloadrequest.html are describing the parameters but couldn't figure out how to do it.
Your question is not clear on what you don't understand. Remember this is not a training forum, the idea is that you should try things, review the documentation and then ask specific questions to get the best out of a forum.
Moreover it is not clear whether you are trying to handle the download request at the Server, or capture the request before the download attempt leaves the BB.
I'm going to assume you want to display a web page on the BlackBerry but make sure that any resource requests that the page generates, are filtered by your program, so that you can supply the data (assuming you have it).
I implemented something like this a while ago and remember that it was not simple to figure out what was going on, but I played with it a bit and it all made sense.
I don't remember using WebDownloadRequest and can't really see how it helps in this case.
The key is WebResourceRequestFilter. You create your own WebResourceRequestFilter making sure you implement the required methods. Then you use WebPage::setNetworkResourceRequestFilter(WebResourceRequestFilter*) to make sure the webpage will ask your WebResourceRequestFilter for its resources. The first method the web page invokes is filterResourceRequest(), and the return from this invocation determines which other methods in your WebResourceRequestFilter, the Webage will invoke.
I suggest you implement a WebResourceRequestFilter, put some debugging in filterResourceRequest(), but always return FilterAction Accept, which means the web page will use its normal processing to obtain the resources. Then try various other FilterAction return values and see what happens...
I've been working on a Flex component and I'd like to write some automated tests for it. The trouble is, the UI testing tools I've looked at (FlexMonkey and Selenium Flex API) don't simulate "enough":
Most of the bugs which have come up so far relate to the way Flex deals with dragging and dropping, which these libraries can't simulate accurately enough. For example, I need to test a case where there is a "drop" event which occurs in the bottom half of a component – neither FlexMonkey nor Selenium Flex API can do that (they may simulate a mouse event, but they won't include coordinates).
So, is there any "good" way to automate that sort of testing?
Edit: After much research, it looks like the only piece of software that can do this is iMacros, which is Windows-only and the interface is... Lacking. So I'm going to be writing my own. Basically, it will put an HTTP interface on java.awt.Robot so code (in any language) can simulate mouse/keyboard events. If you're interested, PM me and I'll keep you updated.
Edit 2: I have published the first version of the framework I wrote, Blunderbuss, over at BitBucket: http://bitbucket.org/wolever/blunderbuss/ . You'll need Jython to run it (http://www.jython.org/), but after that the flex-client example should work.
Videos of Blunderbuss live over at Vimeo:

At the moment this remains a proof-of-concept, as I haven't had the cycles to clean it up and make it more useable… But maybe enough people bothering me would give me that time :)
I've used Eggplant to test Flash and AIR apps without having to add any hooks into the code. It's a great tool but it's quite expensive. It simulates a real user by VNC-ing into a system and uses image recognition - among other things - to interact with the app.
I am definitely interested in your custom Java class, and (though I am not the best at Java (yet...)), I would be willing to help out if you're thinking of making this collaborative.
As to Flash MouseEvents. Unfortunately, there really isn't an accurate way to simulate the drag/drop experience in Flash. MouseEvents, when generated by the mouse, are handled in a very different way than regular events and while you could simulate actions by passing events into the handling functions, or by making the dispatcher fire a new DragEvent( DragEvent.DRAG_DROP..., it will not be the same as having the user interact with it. And for some functionality (like gaining access to the clipboard), nothing inside Flash will accomplish your goals.
To be honest, you're probably headed in the right direction -- using something which is not written in Flash to drive faked mouse events is probably your best bet.
I've never had to use it in Flex but i recently stumbled across some info on automation packages in the MS Surface SDK... after looking into it those classes automated user behavior which can be used for testing i.e. move a fake mouse to this point, perform this action. As you're using Flex mx.automation packages and classes. My guess (and hope) is that you'd be able to achieve what you want using these classes.
You could also try auto-hotkey - it is similarly a macro-editing program but it has proven to be very efficient and you can write scripts and set it up very easily.
