Java :: Cross Domain Calls From Web Browser
Jul 20, 2010
I would like to execute a cross domain http request from a website. Javascript is out, because most browser don't allow cross domain calls. Generally the solution is to use a proxy, but that isn't an option for this project. The other things I was thinking about would be to use Flash or maybe Java. Are there any other platforms that I could use?

How the browser caches .swf and it's content? For example, if I have an image slideshow that load data specified in XML on the domain, will it be cached for access if the same swf is used on the domain or does it have to be re-cached?

Has anyone used or is aware of a service browser to test AMF calls?I am looking for a tool similar to ZamfBrowser ( http:[url].... ), but one that works for the Java environment.ZamfBrowser is geared towards AMFPHP.The idea here is to provide a service browser, that allows developers to test Java services using the AMF protocol, without having to go through the Flex UI all the time. There has got to be something out there already for this, but I can't seem to locate anything..... It's kind of funny and strange that a service browser exists for AMFPHP but not for regular AMF calls in a Java environment.
I would imagine something exists under Blaze or LCDS? ...Trying to find it in the docs but can't seem to find anything ....The best alternative I can think of at the moment is to use FlexMonkey to record stuff, and then to simulate it using that....which is okay I guess but still sucks because you have to go in and create the Flex UI first, whereas with something like ZamfBrowser, you simply point it at the service calls,it tells the server-side developers if their code works, etc. generates the required as3 classes for you... and makes the integration process much easier in a large team.

I created an XML gallery in as3 that will be loading images from a different domain.
I have a .swf (swf1) on serverA that loads an XML from serverB. The XML on serverB points to the image locations located on serverB (I need to host the images on serverB because server A doesn't have enough room).
The images load fine from swf1 locally in Flash, but when I publish swf1 to serverA, the images do not load. My guess is that the XML on serverB is not being loaded correctly because I can see that swf1 on the webpage.
Here is how my XML is set up:
<?xml version="1.0" encoding="UTF-8" ?>
<images>
<image src="http://serverB/media/images/image.jpg" title="This is image 1"/>
</images>

I recently obtained two different domains that point to a subdirectory of another domain server. The swf file I created does not show up when I use the domains that are pointing to the subdirectory of the original domain.I placed an xml file into the root directory that contains the following code:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">[code]....
Nothing shows up. Is there something else I need to do make this work? I created the swf file using CS3.

What my swf (on mysite1.com) need to do, is that POSTing some php values from mysite1.com (paid hosting) to a file on mysite2.com (free hosting) and get the 100% of the html response. I've started this project in AS2 but I couldn't find a function that get the source of a website, so I recreate the project in AS3 with URLRequest and URLLoader. Everything went fine, I've finished the project, uploaded the file, and there comes the cross domain problem. I can't upload/modify any file on mysite2.com because I can only add pages/posts (like a blog). I've read at least 20 forums about this, but can't find the solution.
I know (from the manual) that in later versions of flash and/or AS, the swf file asked the user for permission (like now for the webcam). Is there a way to do this in as3 or any way to bypass the need of the crossdomain xml file? If no, what is that older flash version that can do this permission request or that don't need that xml, (but still can post to php files and get the whole response).
I'm really upset, because I worked a lot of hour on this, and I was so happy that I could finish it, but I didn't know that there is such a big difference in security between local and online swf files.

I have two swf files hosted on different domains [URL] and [URL]. a.swf is loading b.swf and trying to cast it to some interface. When both of these swf files are under the same domain everything works fine. But when they are under different domains I'm getting null after casting b.swf to the implemented interface IComponent. Both of these swfs are compiled with use-network=true and with the same IComponent.as.

I am currently building an XML Socket Server that I am running locally on my computer. My flash client I build as an executable that runs on your computer and connects to mine via port 9000. I want however, to be able to run the flash client as a .swf in a web page on my website. I have a security policy but I don't know if I am using it right. My server is extremely basic still, it has no admin controls or even authentication or anything, right now it just spits back what it is given essentially, while I test out things and stuff. I just don't know how to handle any cross browser stuff.
********************************************All my code works as is if the flash file is compiled as a .exe from any computer. I have tested that. It just doesn't work as a .swf in a web browser.********************************************The file currently is set to just have the user type in their name and then when they move their mouse, it shows up on all other clients with their names next it it. Basically testing a real time activity updates.Here is my code and other files:My config.xml file:

I'm making a flash-based website which would use some information from a separate domain to update its contents. The XML file (document.xml) rests under one domain (let's call it updater2.net), while the core site rests under another (e.g., coredommain.net). I looked at some literature and I picked the simpliest method utilizing this small .php file (called loadXML.php here) and the A/S excerpt:

The other problem is that I cant use a php file on [URL] like a proxy between the sites, because this thing I want to access on mysite2 is IP address dependent, so each different user of the flash file has to be "tracked" different. (like a visitor counter - if each user of the swf access mysite2 through a php on th first site, they are tracked as 1 user (because they are tracked with mysite1 IP address))

Alright, I was told that I need some sort of file on the domain hosting an FLV in order to load it from another domain. Is this true? If so, step by step, how would I go about loading this FLV if I were to say.... put it on newgrounds, and host the video myself. I've posted on the newgrounds forums, but that place is a joke.

Question: How do I create the ability to load a xml file from another domain?
For example, I am creating an embeddable video player that will play on the domain which the xml file resides and also embedded on other sites. I am to the point where the video player completely works on the domain that the xml file resides and when I embed it on another domain, the .flv plays but the xml data will not pull.
FYI, I have complete access to the domain where the xml file resides.
Here are some snippets of security settings that I have been trying to get to work:
Code from Player:
System.security.loadPolicyFile(domain + "data/crossdomain.xml");
Code from "data/crossdomain.xml":
<?xml version="1.0"?>

As you might know, browser's security model does not allow a script loaded in a page from http:[url]... to make cross-domain requests (no AJAX calls to any other domain other than url...).The Javascript file itself could have been served from a different domain altogether (url....) and that is irrelevant. This is the Same-Origin Policy.
Flash also has something similar? But does Flash treat the origin to be the HTML page where the .swf file was loaded or origin is the domain which served the .swf file?
So http:[url]... loads a .swf file from http:[url].... Now .swf can load resources only from [url].... or only [url....? I'm assuming there are no cross-domain.xml files setup on either [url]....

After reading James Ward's post I'm considering using a proxy rather than a crossdomain.xml file. I have a java app, which includes a flex applet, on one tomcat instance and a java web service on another tomcat instance. Does it make sense to have a single (Apache httpd) proxy handle requests for both the app and the web service, thus eliminating the cross domain restriction?how to deal with the cross domain issue are welcome.

I'm running a rails3 project with an external asset host for all javascript, images, swfs etc. This is on a completely different domain. So know I tried to embed some SWFs using swfobject. In development (same host) everything works fine, but in production (different hosts) it doesn't start the flash (firebug shows the file is loaded but nothing appears on the page). I already put this crossdomain.xml file in the root of the asset host but it does not change anything at all.
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />
[code]....
What can I do to make it work? The SWFs I'm using are not developed by me, so I cannot change them. Some are simple sounds, others are videos and small "apps". I don't want to have to make rails serve the swfs.

I have a flash accordion embedded using SWFObject. The SWF and related XML file are hosted on one domain. I have about 10 sites embedding this SWF from it's hosted location, both the SWF and the XML. The accordion links to various pages of my domains. The domain in which the SWF and XML file are hosted, the links work as expected. The other domains that the SWF is not hosted on, the links do not work at all. I verified it's a cross domain issue by placing the SWF and XML files locally on each domain and they worked, but this is not how I want it setup. I attempted to use crossdomain.xml and allow access from all hosts but that didn't work either.

I have a project I am working on, but first I needed to test this. I have a SWF named "index.swf" (with a index.html), that is running on a rented server of mine. [URL].
-The SWF contains 2 layers.
-The first layer contains 2 dynamic textfields names "text1" and "text2".
-The second layer has some actionscript:
ActionScript Code:
stop();
var loadFile:LoadVars = new LoadVars();
loadFile.load [URL];
loadFile.onLoad = function(succes:Boolean){
text1.text = this.variable_me;
text2.text = succes;
}
The "test.php" is located on the second domain. This is the code written in it is:
PHP Code:
<?php echo "variable_me=works&";?>
So the SWF-file on the 1e domain has to load the php file from the second domain. But it doesn't work.
text1 displays: "undefined"
text2 displays: "false"
But if I call the php file in a regular browser (like this "[URL]") it displays:
variable_me=works&
My flash code isn't wrong, i have tested this local. My PHP file is OK.

I have a banner that loads in XML and an image. The banner.swf is on domain1, while the image and XML data is on domain2. I got the data.xml to load using a crossdomain.xml policy file to allow crossdomain loading of the data.xml. The only problem I have now is loading in the image. Locally it works fine, unless I don't have the swf and the image in the same directory. I guess the real question is, how do I load in an image with XML, if the swf and the image are not in the same directory. My code is underneath:
Code:
myXML = new XML();
myXML.ignoreWhite = true;
myXML.onLoad = loadXML;
myXML.load("mpu.xml");
