Pinned topic Remote Control - Unable to download resource

‏2012-05-29T13:59:00Z |
Hey all,

When we try to start a session through the TRC server we get this error:


com.sun.deploy.net.FailedDownloadException: Unable to load resource: http:
//xxxxxxxx.xxxxxx.xxxx:80/trc/apps/controller/TRCConsole.jar at com.sun.deploy.net.DownloadEngine.actionDownload(Unknown Source) at com.sun.deploy.net.DownloadEngine.getCacheEntry(Unknown Source) at com.sun.deploy.net.DownloadEngine.getCacheEntry(Unknown Source) at com.sun.deploy.net.DownloadEngine.getResourceCacheEntry(Unknown Source) at com.sun.deploy.net.DownloadEngine.getResourceCacheEntry(Unknown Source) at com.sun.deploy.net.DownloadEngine.getResource(Unknown Source) at com.sun.javaws.LaunchDownload$DownloadTask.call(Unknown Source) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)


Java version is 6, and is fully updated.

Anyone got an idea what's wrong?

Thanks in advance

    Hi,

    The first thing to check would be if that URL works if you paste it in the browser in that same machine where you are trying to launch the controller.

    If that works then it could be a matter of having incorrect proxy settings in the Java Control Panel, so it might be worth checking that.

    If it doesn't work from the browser either then it could maybe that the hostname can't be resolved.

      Hey Jose,

      Well, the controller is not in the inside LAN. (we're using the broker)

      We published the website through a 'reverse proxy' appliance.

      But I think we found the problem, the broker(is in DMZ) is not yet reachable from outside the LAN at this moment.

      Could that be the problem?

        Hi,

        At that point the broker is not yet involved. This failure seems just in Java Web Start trying to download the controller jar's file so it can be launched. Once it's launched then it would try to connect to the broker and fail because of the other issue you have discovered, but this is not (yet) the problem.

        I would still look into troubleshooting this with a local browser pointing to that URL and see if that works. I'd imagine you might be having trouble reaching the reverse proxy with the hostname in the URL or maybe the reverse proxy is not passing all requests correctly to the TRC server.
