I'm needing a webservice for capturing and entire website and export it to JPG or PNG.
I'm using Paparazzi on my mac, but I've a linux server and would like to that on linux.
Any idea? Do you know any webservice?
http://browsershots.org/
Is this the kind of capture you are looking for?
On linux I use screengrab for firefox.
Online you should try http://browsershots.org, it provides shots from many different browsers, I use it when I have to test the appearance of a page on different web browsers.

Windows has hta files. They are a bit like html files. They include html5 and javascript but they launch as desktop applications which are fully-trusted. (They use a file called mshta.exe found in the IE installed components in order to run.)
The great thing is you can port many web pages to desktop applications with just a few extra lines of code.
Info can be found here:

Do the latest releases of Linux (and possibly apple mac desktops) have an equivalent of hta files?
If you are aiming to deliver HTML content you can take a much more flexible road: use a GUI framework with HTML capabilities like QT.
here there is a simple example about how to use webkit ( a rendering engine for the web ) to embed a fully working web browser in your GUI, and QT works under many desktop and mobile platforms.
You can try to use node webkit for this purpose.
I want to create a new application (which I will sell) that uses web browser control to automatically post things on the internet etc.
I did some research, and it looks like the primary choice for most people is .NET webbrowser control (via an instance of IE).
I don't want to do this because I want customers that own a Mac and Linux to be able to use my software.
With that said, are there any web browser control classes or toolkits available that can work on all OSes (e.g. something that uses Java?)
Thanks in advance!
UPDATE:
Web browser control is basically the ability for a program to act like a human and open a web browser and go to websites, fill out forms, check email (lol) etc.
Firefox, Chrome, Safari. I think virutally everything but IE works on all the OS's. Not suprising really when you think it's made by microsoft.
Selenium libraries let you create scripts (with a GUI or one of the supported languages [it has got most of the popular ones like Java, Python etc.]) for browser automation on all popular browsers (including chrome, which works on all OSes like mentioned by other answers).
Here's the deal. I've animated + coded a variety of 'screensavers' in Actionscript3/Flash. They make extensive use of the timeline, AS3 code, the TweenLite library, and embedded fonts. That's the limit of my programming knowledge. I've tried, to no avail, to convert my .SWFs into screensaver files using a variety of software, such as InstantStorm. Somehow it never works, the code never executes properly, it's a disaster.
So, I'm wondering if it's possible to make a screensaver that simply contains an embedded browser, and have it point to my .SWF file, hosted on my web-server. Basically, imagine a full-screen website acting as a screensaver.
If this is possible, what is the EASIEST and FASTEST way for me to whip up a solution for both PCs and Macs? Language, etc. I'm hoping something that has a library I can simply draw from to embed the browser view :)
My startup is developing a product to do exactly this, it's called Screensaver Ninja and you can find it at https://Screensaver.Ninja.
You can set many different web pages with different timers. The configuration tool allows you log in and navigate to the page you want to display:
It uses WebKit, on Mac OS X it uses Safari's and on Windows it uses Chrome's and in both cases it has a separate session from any other browser installed on the computer.
Here's a small Windows-only solution:
https://github.com/cwc/web-page-screensaver/releases
You could modify this open-source one for the Mac so that it's hard-coded to your URL:
http://www.liquidx.net/blog/2010/11/13/webviewscreensaver-for-mac/
Modify hasConfigureSheet() to return NO and change the URL in kScreenSaverDefaultURL. And change the name!
I'm tyring to get phonegap up and running on blackberry storm (9530 simulator). I had been testing my webapp from withing BB's built in browser, and it was looking ok, but then it totally bit once I tried to look at the some code from within phonegap, even though I was pointing phonegap to the same url (I hadn't yet gotten to the point of running code locally on the device).
I tried a test case on google and got similiar results. see below. I suspect that I'm missing something basic here. I would have expect both images to be nearly identical.

[Update]
To shed some light on what is happening, I ran the browser and the embedded browser (phonegap) against the W3 mobile web acid test: http://www.w3.org/2008/06/mobile-test/
I definitely notice differences between the two, but I don't yet know the 'why' and the 'how-to-address'.

BTW - I ran this earlier today and got a couple more green square than just now.
Acid via browser embedded into phonegap
http://www.eleganttechnologies.com/outside/ImgDeviceBb9530PgAcid.jpg
Disclaimer: I don't know anything about phonegap, but have a pretty good theory. By default the embedded browser control on BlackBerry uses an older version of the rendering engine than the BlackBerry browser itself does.
At the BlackBerry developer conference last year, a talk was given about this, and there's an undocumented option to use the newer rendering engine. \
The option ID is 17000 (yes, a magic number, which could change, use at your own risk etc), and should be set to true. Not sure how you'd pass this option through phonegap (I'm not familiar with the toolkit) but using the BlackBerry APIs it's something like:
BrowserContent content;
...
content.getRenderingOptions().setProperty(RenderingOptions.CORE_OPTIONS_GUID, 17000, true);
I don't know the specifics of the browsers you are using, but I do know that most of the big sites will detect your OS + browser combination to decide what HTML to show you.
If Google is seeing a different user agent, you might get a generic mobile version of the HTML instead os the Blackberry specific HTML you get for the built in browser.
If you have access to a web server, try hitting it with both browser setups and see if there is any difference in the log file. That might tell you something interesting.
As we can see in your Acid tests...
One browser (the built-in one) is reporting correctly as a BlackBerry9530, and the other (phonegap) is not presenting the user-agent ["Testing with ."].
In this case, Google is providing you with the default view of their homepage, whereas when you are reporting yourself as a BlackBerry device, you will get the BlackBerry specific rendering.
By the sounds of things, using phonegap is removing the default user-agent (most probably because it's not recognising your device). As phonegap is open-source, the best bet is to get in there, and debug it and find out what happens with the user-agent when the http requests leave the device and track it back from there.
Maybe one browser has capabilities that another one does not?
Hm. By looking at the screenshot I would say that the second page is probably missing some resources. It may be missing some images, scripts and the CSS files, which would explain different l&f. Knowing how Blackberry Browser Field API works, I would guess that the implementation that uses the BrowserField was not done correctly. Just my guess. In addition to that, when the browser field is initialized the caller needs to configure it properly by enabling the appropriate browser features - scripts, styles etc. Again, the API is done in a very weird way, I have gotten myself into this trap once. When setting the options, you cannot just create one mask (like CSS | WML | SCRIPT) and make one call. Options are numeric and, I believe, non-overlapping - but you still need to call the API for setting each option independently.
Also the way asynchronous loading of the resources for BrowserField takes time to understand.
Just my $0.02.
How can i create a browser component in J2ME which can display web pages inside an application? Is there any API available for this ? or is this really possible ?
My experiences:
J2MEPolish has HTML browser. It costs 990EUR per app and you need to use J2MEPolish to use it. But be warned: their HTML browser has many issues, it supports forms and other advanced elements, but if you try to get something you like then rendering quality is bad (e.g. no spacing, defaults to center view etc). Free evaluation/GPL is available.
PocketLearn J2ME HTML Component - http://www.j2mehtml.com/ seems to have less features but much better rendering quality. This is not free as well, and there they do not provide any useful evaluation download or public license fee info.
J2ME cHTML browser is free and open source, but no docs (and probably no quality too)
As far as I know, the only browser written in J2ME is Opera Mini (not to get confused with Opera Mobile, which is a different thing). It runs amazingly good even on very low end phones, but most of the HTML handling is done on a special server that Opera hosts, and the client gets optimizes, preformatted, binary data to display.
Doing everything on the phone using Java might be hard or even impossible. You'd be able to code up a browser that displays very basic HTML pages, but doing it right even for more complex pages seems to be impossible on J2ME because of the limited memory and CPU.
I could imagine that some high end phones come with a custom API to embed a native browser into you Midled, but the standart J2ME definitely does not have this.
The only portable way to display a web page in the browser is with:
MIDlet.platformRequest(String URL);
On some mobile, this will terminate the J2ME application though.
The Content handling API is what you're looking for.
That's JSR 211.
Unfortunately, to do what you want, you would need to find a handset that contains an implementation of JSR211 that is both complete and correct.
That doesn't exist yet as far as I know.
The only J2ME emulator that I know that may allow you to launch a web browser window (outside of a MIDlet) is the Nokia Series60 emulator. That doesn't have a complete implementation of JSR 211.
Try this
http://sourceforge.net/projects/fire-j2me/
Unfortunatley there are no built-in components in Java ME to render html.
You can try htmlBrowser component of the j2mePolish toolkit (www.j2mepolish.org)
