I am getting the following exception when trying to launch designer from ignition web page. I am able to download the “designer.jnlp” file but on launching the following errors are reported : Exception : com.sun.deploy.net.FailedDownloadException: Unable to load resource: [172.16.1.72:80/main/system/launc … igner.jnlp](http://172.16.1.72:80/main/system/launch/designer/designer.jnlp) 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.deploy.net.DownloadEngine.getResource(Unknown Source) at com.sun.javaws.Launcher.updateFinalLaunchDesc(Unknown Source) at com.sun.javaws.Launcher.prepareToLaunch(Unknown Source) at com.sun.javaws.Launcher.prepareToLaunch(Unknown Source) at com.sun.javaws.Launcher.launch(Unknown Source) at com.sun.javaws.Main.launchApp(Unknown Source) at com.sun.javaws.Main.continueInSecureThread(Unknown Source) at com.sun.javaws.Main$1.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Wrapped Exception : java.net.ConnectException: Connection refused: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at sun.net.NetworkClient.doConnect(Unknown Source) at sun.net.www.http.HttpClient.openServer(Unknown Source) at sun.net.www.http.HttpClient.openServer(Unknown Source) at sun.net.www.http.HttpClient.(Unknown Source) at sun.net.www.http.HttpClient.New(Unknown Source) at sun.net.www.http.HttpClient.New(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.plainConnect(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.connect(Unknown Source) at com.sun.deploy.net.BasicHttpRequest.doRequest(Unknown Source) at com.sun.deploy.net.BasicHttpRequest.doRequest(Unknown Source) at com.sun.deploy.net.BasicHttpRequest.doGetRequest(Unknown Source) 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.deploy.net.DownloadEngine.getResource(Unknown Source) at com.sun.javaws.Launcher.updateFinalLaunchDesc(Unknown Source) at com.sun.javaws.Launcher.prepareToLaunch(Unknown Source) at com.sun.javaws.Launcher.prepareToLaunch(Unknown Source) at com.sun.javaws.Launcher.launch(Unknown Source) at com.sun.javaws.Main.launchApp(Unknown Source) at com.sun.javaws.Main.continueInSecureThread(Unknown Source) at com.sun.javaws.Main$1.run(Unknown Source) at java.lang.Thread.run(Unknown Source) I am using the Mozilla Browser 3.5, basically I am in the same sub net as the machine I am browsing and my browser setting is “No Proxy” .

Well I have been trying and finally able to get it to work in chrome . I tried launching the Designer from I.E v8 and had the same error as above with no Proxy set . I have downloaded Chrome 4.1 and using the same settings i.e “No proxy” I am able to launch the designer finally !!! I have still not understood why Mozilla and I.E fail to launch the designer . Suspect there is something more than just proxy and network settings . ---

Go into the “Java” item under the Windows Control Panel and look at the “Network Settings…” window. What is it set to? ---

Interesting - it sounds like those browsers may have a proxy set that you don’t want to use. Try “Direct” ---

I have tried “Direct” with the same error on Mozilla and I.E . Chrome works fine in both “Use Browser” and “Direct” mode. ---

This is pretty strange. What version of Java are you running, and what version of Ignition? ---

They need to know more than just Java 1.6 It will be something like this: Sun Microsystems Inc. 1.6.0\_19 The \_19 is an incremental release and there are/were problems with some. There is a \_20 out and maybe a \_21. Dennis
