Swf not loading at localhost server

i've come across a issue regarding publishing swf which is
createing a problem to me.
Actually i have published and run the swf file on my system,
here it is running properly, but when i send to other people it is
not running.i guess it may be due to the publish settings that may
b i've changed in between.so what should be the publish settings so
that it should also run on another systems.
plz tell me the solution for this

yes.. actually swf is calling a RSS feed XML from web.when i
give the local path of the feed from localhost at my system, then
it works,but dont work when the path is given of RSS feed coming
from web.

  • Gallery tree swf not loading

    I am using the gallery_tree.fla provided in the Samples for
    Flash 8 Pro to build a small photo gallery, substituting the name
    of my xml file in this line of code in the action script:
    treeDP_xml.load("bbq_gallery_07.xml"); .
    I used the gallery_tree.xml, substituting my image filenames
    in the nodes. I placed the images, the .xml and the .swf in the
    same folder. The .swf will play if I open it on my local machine in
    a browser, but on the web server, it just continues to show the
    loader but no images or tree.
    My .xml and Actionscript is attached. Suggestions as to my
    problem?

    Seems odd it will only run once. Usually if a cache problem
    you get the same
    results even when you update the movie or server scripts.
    If it is
    http:// it is not local even if from the browser
    cache.
    Verify the html is validated.
    Check to see if this applies to all swfs. Create a simple
    hello world swf
    that connects to a JSP script that returns a simple value to
    Flash. If that
    seems to work, then the problem is in the JSP or
    Actionscripting coding.
    Check you can load the JSP script repeatedly using a direct
    call to it on
    the browser line using
    http://.

  • Applet does not load on app server when Free Design Layout

    Hi,
    I have to embed a an applet in a webpage of an web application. Before I go on to anything.. let me first tell you, I am using Netbeans 6.0
    As shown in the tuorial:
    [http://www.netbeans.org/kb/articles/tutorial-applets-40.html]
    1. I first made the "Applet" source say HelloApplet. java. After compiling and running it I get the HelloApplet.jar.
    2. I created a WebApplication and then from the properties -> packaging -> I "Add Project" HelloApplet.jar.
    3. Then I a webpage I "embeded" the applet.
    4. I run the web app and the applet gets loaded and everything is just fine.
    But before I go on I must tell you that the applet was designed in Null Layout. Now I edited the applet source once again and changed the layout to Free Design Layout*. ( this is available from Netbeans..on the HelloApplet.java .. go to the design view.. right click on the form and from the context menu you can change the layout to FreeDesign or whatever you might want).
    When I expand the "Libraries" node I see the that the library Swing Layout Extensions - swing-layout-1.0.3.jar has been added.
    When I "run" the "HelloApplet.java" file, the applet is shown in the appletviewer. No problems with that.
    But!
    When I try to Clean & Build and Run the WebApplication, the applet does not get loaded. On inspecting the java console I see the following error:
    java.lang.NoClassDefFoundError: org/jdesktop/layout/GroupLayout$Group
    at java.lang.Class.getDeclaredConstructors0(Native Method)
    at java.lang.Class.privateGetDeclaredConstructors(Unknown Source)

    at java.lang.ClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClassInternal(Unknown Source)
    ... 10 moreIt clearly shows that the Free Design Layout has something to do with the GroupLayout which can be found by expanding the "Swing Layout Extensions - swing-layout-1.0.3.jar". Now when the HelloApplet.jar is created only the HelloApplet.class file gets included together with some other data but NOT the swing extensions. Hence when I run the web app the class file looks for the GroupLayout.class definition but can find it in the jar as its not included when the HelloApplet.jar is created.
    But with null layout there isint a problem because null layout takes the definitions from the JRE on the machine.. and so it runs without a hitch.
    My Question is : How can I run the applet with Free Design Layout? or is it possible to package the swing layout extensions in the HelloApplet.jar?<</u>
    Thanks for all your replies.
    Cheers.

  • SWFs not loading in Air 4.0... for iOS

    Hi,
    I've read some of the posts about the problem of SWFs not loading in iOS.  This seemed to have to do with the SWFs having code.  We removed code from the SWFs and In previous releases, using previous SDKs (I don't remember the last one that worked) we had everything working.  But in the latest version compiled with the latest SDK (4.0...) none of the SWFs load.
    of course I'm learning about this late in the game.
    One more piece of information.  I did a test with an application that just loads one codeless SWF and have exactly the same result. 
    If anyone has any ideas, I would be very grateful.
    Best regards,
    Chris McLaughlin

    Hi,
    So code or no code external SWFs require a loader context.
    I borrowed this directly from a kglad response:
         var lc:LoaderContext=new LoaderContext(false,ApplicationDomain.currentDomain,null);
    When I add the LoaderContext to the loader (at least with my experimental app) the SWF loads.
    Also from kglad's example: yourloader.load(yourexternalswf.swf,lc);
    Thanks kglad.

  • External .swf not loading on HTML pages

    Good morning,
    I'm having trouble and I was hoping someone could shed some light on what I'm doing wrong. I have a main .swf file from which external .swf files are being loaded through the use of buttons.
    When I preview the animation, everything works just fine. The problem occurs when I put the animation on the website where it needs to be. The main animation appears like it's supposed to, but the buttons are not successful in loading the external .swf files. I've made sure that all .swf files are on the server but still nothing. Could anyone help? I'm not sure what the problem is.
    Here's the AS:
    stop();
    var presentationLoader:Loader = new Loader();
    addChild(presentationLoader);
    //Navigation
    presentation1.addEventListener(MouseEvent.CLICK, buttonClick);
    presentation2.addEventListener(MouseEvent.CLICK, buttonClick);
    presentation3.addEventListener(MouseEvent.CLICK, buttonClick);
    presentation4.addEventListener(MouseEvent.CLICK, buttonClick);
    presentation5.addEventListener(MouseEvent.CLICK, buttonClick);
    presentation6.addEventListener(MouseEvent.CLICK, buttonClick);
    function buttonClick(event:MouseEvent):void
    presentationLoader.load(new URLRequest(event.target.name + ".swf"));
    function homeClick(event:MouseEvent):void
    presentationLoader.unload();
    Thank you,
    - Cmarcoux

    For anyone having a similar problem in the future, the solution is in bold:
    stop();
    var presentationLoader:Loader = new Loader();
    addChild(presentationLoader);
    //Navigation
    presentation1.addEventListener(MouseEvent.CLICK, buttonClick);
    presentation2.addEventListener(MouseEvent.CLICK, buttonClick);
    presentation3.addEventListener(MouseEvent.CLICK, buttonClick);
    presentation4.addEventListener(MouseEvent.CLICK, buttonClick);
    presentation5.addEventListener(MouseEvent.CLICK, buttonClick);
    presentation6.addEventListener(MouseEvent.CLICK, buttonClick);
    function buttonClick(event:MouseEvent):void
    presentationLoader.load(new URLRequest("../../media/flash/" + event.target.name + ".swf"));
    function homeClick(event:MouseEvent):void
    presentationLoader.unload();
    For the animation to work on a website, the file path was needed.

  • Xml file not loading from different server

    Hi,
    I have a simple flash banner that is pulling a number from an xml file on a different server. When it gets to the frame where the number should be it just says "transferring data from eckul.com" and will not actually pull in the number. Unfortunately I can't put the files on the same servers. Any help would be much appreciated, below are the links and the xml code I'm using followed by the action script. Cheers
    http://www.sainters.net/newsletters/2010/flash_test_membership2.html
    http://www.eckul.com/number.xml
    <?xml version="1.0"?>
    <inventors>
        <person>
            <name>892</name>
            </inventors>
    function loadXML(loaded) {
    if (loaded) {
    _root.inventor = this.firstChild.childNodes[0].childNodes[0].firstChild.nodeValue;
    _root.comments = this.firstChild.childNodes[0].childNodes[1].firstChild.nodeValue;
    name_txt.text = _root.inventor;
    comment_txt.text = _root.comments;
    } else {
      trace("file not loaded!");
    xmlData = new XML();
    xmlData.ignoreWhite = true;
    xmlData.onLoad = loadXML;
    xmlData.load("http://www.eckul.com/number.xml");

    so, in frame 1 of your fla before you execute that cross-domain load method, use:
    System.security.loadPolicyFile("http:www.yourcrossdomain.com/subdirectoriesIfNeeded/crossd omain2.xml");
    where the following (crossdomain.xml) is in www.yourcrossdomain.com's root (IF you want to allow allow subdirectory policy files):
    <!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
    <cross-domain-policy>
    <site-control permitted-cross-domain-policies="all"/>
    </cross-domain-policy>
    and in the subdirectory (and its descendents) that you want to allow access put crossdomain2.xml:
    <?xml version="1.0"?>
    <!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
    <cross-domain-policy>

    </cross-domain-policy>

  • Very Slow running dashboards/swf not loading

    I have built a number of dashboards and sent them round to colleagues in my company (either embedded in powerpoint or as swf to open in IE). We have no probelms viewing these dashboards internally but when we send them out to clients they cannot view them.
    It seems like the swf files are just not loading, or are incredibley slow (so slow that the client has given up on them) has anyone else encountered problems like this? Could there be some security issues; when the files pass onto another network the swf is halted?
    Hope someone can help!

    There is known issue with  xcelsius 2008 when exported to PPT..
    Check this and do the work around mentioned.. it will work,but very slow.
    I don't know its a problem with xcelsius  or with my laptop?

  • Urgent! external swf not loading with swfobject!

    hello there,
    I have a swf that loads another one into it through an empty
    movieclip - When i embed it with swfobject it doesnt appear.
    My guess is that i would have to mention the external swf in
    the flashvars ... Done that with no success.
    Does anyone have an idea of what could be causing me this
    trouble?
    thanks

    Generally the problem will be that the path of all externally
    loaded content is relative to the html page, NOT the swf location.
    If everything is in the same folder then that isn't it.
    Otherwise nice dice is correct, we will need to see your code
    to go further.

  • SWF not loading on website---Help please...

    Hi everyone,
    I'm not really new to Flash; I know how to get around persay. Though this task has me almost in tears. I'm trying to put a video playlist on my website. It has 3 videos. The playlist requires a few files in which I put in a folder named "video testing". Heres what I did:
    I created a video playlist in Adobe Flash CS4 with some Actionscript.  I published it in html and flash(swf). Afterwards, I saved the playlist as “MyVideoPlaylist”.  I put all of these files in a folder named “video testing”. This folder contains:   “MyVideoPlaylist.swf”   “MyVideoPlaylist.fla”   “playlist.xml”   “video”  “thumbs”. The video folder contains all the videos for the playlist and the thumbs folder contains the thumbnail images for the playlist. I opened up Filezilla and uploaded all files in that folder to the “flash” folder within the root directory. Since I’m using wordpress I browsed to the page that I wanted to put the flash in and placed the following code in the html section:
    <object width="425" height="344"><param name="movie" value="http://www.burnnoticefanatic.com/flash/MyVideoPlayer.swf"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.burnnoticefanatic.com/flash/MyVideoPlayer.swf" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>
    After pasting the code, I viewed the page and saw that the video was not loaded, just a blank white background. Though, when right-clicked, you see the flash options. When I type in the full URL to the swf, the playlist loads correctly. You can see it here: http://www.burnnoticefanatic.com/flash/MyVideoPlaylist.swf
    When its embedded with the code above, it doesn’t work.  
    To see what I mean can be found on the page:  http://www.burnnoticefanatic.com/video-gallery

    What does "http://www.burnnoticefanatic.com/promo.swf" have to do with the file you have been talking about? 
    As far as you saying "it could be that the swf file needs the videos and thumbs to play it correctly"... I assumed you were attempting to use them.
    It's hard to solve this if the right players aren't in the game.  The code you are using in the web page is old-style code.  I would expect that if you publish an html file using Flash and use that code for embedding your file it will solve some potential problems, though those may not have been encountered yet.

  • Iweb not loading properly to server?

    Hi I have used Dreamweaver in the past but decided to try iweb this time. I built a site www.southernlakestravel in iweb and have both published it to a local folder for safe-keeping and also to my webserver (2day.com) . I have also tried to ftp the site in dreamweaver. My problem is that all the fites load onto the server (whether published directly from iweb or via dreamweaver ftp) BUT I can almost never get the navigation bar to show up - just appears as a little dot on the top left side. I also note a lot of the images are not loading properly. If I resize them in photoshop to fit then it seems to be more secure. When I look at my files serverside and remoteside I have the folder name, the index file then the subfolder name with all the page files and a second index file and the script files. I notice that the script files include a js navigation menu. Is there a problem with the heirarchy of these files and whether the main index page can "pull these". Should the server be looking to document or root folder. I am at my wits end to know what to do. I can click on links between pages (click on activities in the above page and then go to some of the links shown), but basically the pages load without the iweb style navigation menu showing up at all and with many of the photos only half showing. Also, why does it become southernlakestravel/southernlakestravel?
    I am about to give up on iweb.
    Meg.

    You have the double domain name because the second one is your site name - you gave your site this name in iWeb and you can change it to something shorter and more suitable and then this won't happen.
    As you have seen, it is the way that iWeb works - when you publish to a local folder, iWeb produces a site folder with a separate index.html file - there is another index.html file inside the site folder itself so what you need to do is upload the site folder to the root folder and then you upload hte separate index file that will sit outside the site folder and point in towards it.
    The iWeb page template navigation menu is javascript based and sometimes if there is a black dot, this means that all the files are not being uploaded to the server correctly.
    It would suggest that you publish your site to a local folder and then view your site by opening the html pages and seeing if there is a problem there before you upload your site.
    i would then suggest that you then use something other than Dreamweaver to upload your site - download Cyberduck for free - this is a dedicated ftp programme and may be better than Dreamweaver for uploading. With Cyberduck, you can see exactly where everything is being uploaded to.
    In the end, if you really want to eliminate your site name, then you can - you just need to upload the contents and the contents only of your site folder.  This means that you will not need the extra index file - simply select all the contents of your site folder and upload these with the index file that is in there already.  If you do this your url will just be http://www.domain.com/page name.html without the site name at all.

  • SWF not Loaded 100% using SWFLoader !!!!!!!

    HI all,
    Iam working in Flex Project, i got hung up with a issue with SWFLoader, I have main application and a sub application developed in FLEX 3, the sub application contains the flex pages of DashBoard screen, the SWF of sub application is loaded in main application using SWFLoader. if the browser is opened full , the SWF is loaded 100% , if the browser is opened 75% the swf is not loaded fully. when the browser is maximized the SWF is not displayed full screen. the issue is THE SWF IS GETTING LOADED ACCORDING TO THE BROWSER SIZE, WHEN BROWSER IS MAXIMIZED THE SWF IS DISPLAYED SAME WHEN BROWSER WAS 75% AND NOT EXPANDED .if anybody come across this issue, pls post reply , thanks.
    The swf of subApplication is loaded in the main with the code:
    <mx:Canvas id="dashCanvas" creationPolicy="all" cachePolicy="on"width="100%" backgroundColor="#FFFFFF" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
    <mx:SWFLoader id="dashBoard" trustContent="true" width="100%" height="100%" scaleContent="true" autoLoad="true" source="@Embed(source='../../../../assets/appl/dashboard/dashboard.swf')" />
    </mx:Canvas>
    The width and height of thr subApplication and the Main Application are set as 100%.
    when the width and height of the subApplication is set as :
    width=Capabilities.screenResolutionX;
    height = Capabilities.screenResolutionY;
    the SWF loads fully and correctly when the browser is opened 100% but when the browser is 75% open, the SWF gets loaded according to the browser.
    Thanks & Regards
    Gowrishankar R

    Setting width/height will turn off % sizing and might affect resizing as you have now fixed its width/height.
    See if the resizeHandler gets called on the Application.  You may also need height=100% on the Canvas

  • My page is not loading correctly after server work? Help?

    A couple of days ago I was having issues uploading files to my webserver and come to find out, they were working on something on their end. 
    So okay.  But now, certain pages on my website are not loading correctly.  These are not necessarily pages I was working on during the issues
    with the server.  Whats more, they appear to load fine in Mozilla, but they don't load correctly in Chrome.  Chrome is what I have been using lately,
    and I did not have any issues with these pages prior to a few days ago.  Basically the formatting on the page is all screwed up.  I contacted the techs
    on the sever side and they said it what outside their scope and said it was likely server/script incompatability???  I have no idea what this is or why
    since my page was working just fine a few days ago.  The "home" page loads correctly, but basically if you click on "About" , "contact" or any of
    the other pages you will see what I mean if you are using Chrome (unless it is actually my computer?)  I would appreciate any input you might have,
    and here is the link to my page:
    http://rickcicciarelli.com/AntiqueTargetThrowers.html

    So I realized that I must have messed with the screen resolution by accidently touching the  touchpad on my laptop.  So it appears, that the page loads funny in certain screen resolutions.  What doesn't make sense is that the laptop will be set at a certain resolution and the "home" page loads properly, but the other pages shrink down and load funny.  So when I change the  screen resolution to what it is 'suppose' to be, the page loads fine.  So this begs the question, why should it load funny in a different screen resolution?

  • Cap 2 - Embedded SWFs not loading

    Hey everyone...
    I'm building Captivate tutorials using Cap 2. As part of
    these, I'm creating separate simulations in Captivate, publishing
    them, then dropping the SWFs into slides on my larger project.
    So, the problem I'm having is that when I'm progressing
    through the larger Captivate module, I'll get to a slide that
    begins with one of the swf animations, and the slide audio will
    begin and the slide progresses, but the embedded swf is still
    loading. So, what happens is by the time the swf finally loads, my
    main timeline has moved almost completely past the animation...so
    basically, it screws everything up.
    I've tried using a preloader for the whole project, set to
    100% and that didn't fix the problem, which leads me to believe
    that the animations aren't actually loaded in that preloading
    process.
    I've tried synchronizing the animation with the project...no
    luck there. I've made sure that the embedded animations don't have
    preloading of their own. Nothing seems to work.
    Ideally everything would load up in the initial preloading,
    but I'd settle for having each slide wait until the contents are
    completely loaded before beginning.
    Any suggestions anyone might have would be greatly
    appreciated.
    Thanks,
    jb

    So I figured out a workaround for this issue, if anyone is
    interested.
    I republished the Cap projects I was imbedding into the
    larger project in Flash 8 format, and published the larger project
    in Flash 7 format. Doing so causes the larger Cap project to
    publish the Flash 8 swfs along with the rest of the published
    files, and then calls to those files instead of trying to imbed the
    swfs within the larger project. Works like a charm.
