Created attachment 229 [details] Screenshot of the error dialogs that pop up when starting Gears.jnlp. Starting the gears demo via http://jogamp.org/deployment/webstart-next/jogl-demos/Gears.jnlp on Mac OS X Version 10.6.6 with all updates installed yields the following error: Exception: com.sun.deploy.net.FailedDownloadException: Ressource konnte nicht geladen werden: http://jogamp.org/deployment/webstart-next/jogl-demos/jogl-demos.jar at com.sun.deploy.net.DownloadEngine.actionDownload(DownloadEngine.java:1372) at com.sun.deploy.net.DownloadEngine.getCacheEntry(DownloadEngine.java:1525) at com.sun.deploy.net.DownloadEngine.getCacheEntry(DownloadEngine.java:1503) at com.sun.deploy.net.DownloadEngine.getResourceCacheEntry(DownloadEngine.java:1609) at com.sun.deploy.net.DownloadEngine.getResourceCacheEntry(DownloadEngine.java:1534) at com.sun.deploy.net.DownloadEngine.getResource(DownloadEngine.java:217) at com.sun.javaws.LaunchDownload$DownloadTask.call(LaunchDownload.java:1979) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:680) Cause: java.util.zip.ZipException: ZIP file must have at least one entry at java.util.zip.ZipOutputStream.finish(ZipOutputStream.java:304) at java.util.zip.DeflaterOutputStream.close(DeflaterOutputStream.java:146) at java.util.zip.ZipOutputStream.close(ZipOutputStream.java:321) at com.sun.deploy.net.HttpDownloadHelper.download(HttpDownloadHelper.java:228) at com.sun.deploy.cache.Cache.downloadResourceToTempFile(Cache.java:568) at com.sun.deploy.cache.Cache.downloadResourceToCache(Cache.java:529) at com.sun.deploy.net.DownloadEngine.actionDownload(DownloadEngine.java:1347) at com.sun.deploy.net.DownloadEngine.getCacheEntry(DownloadEngine.java:1525) at com.sun.deploy.net.DownloadEngine.getCacheEntry(DownloadEngine.java:1503) at com.sun.deploy.net.DownloadEngine.getResourceCacheEntry(DownloadEngine.java:1609) at com.sun.deploy.net.DownloadEngine.getResourceCacheEntry(DownloadEngine.java:1534) at com.sun.deploy.net.DownloadEngine.getResource(DownloadEngine.java:217) at com.sun.javaws.LaunchDownload$DownloadTask.call(LaunchDownload.java:1979) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:680)
What video card do you have? I just ran from that link on OS X 10.6.6 and the gears demo came up OK. I'm using Safari 5.0.4 (6533.20.27) and an NVIDIA GeForce 320M.
I am using a 2.66 GHz Intel Core i7 MacBook Pro with 8 GB of 1067 MHz DDR3 ram. The graphics card is a NVIDIA GeForce GT 330M. I just tried again in case something has changed. Same error.
Could you give me your Safari and JVM versions? Hopefully something is different between our systems that will give us a clue what's going on. Also, please make sure you can manually navigate in Safari to http://jogamp.org/deployment/webstart-next/jogl-demos/ in your browser and manually download jogl-demos.jar -- perhaps there's a firewall or permissions problem somewhere.
You might also try: - Updating Java - Checking for conflicting JARs in ~/Library/Java/Extensions and /Library/Java/Extensions Other users have solved similar problems by doing one of these things.
My Safari is version 5.0.4 (6533.20.27). Java is also up to date: java version "1.6.0_24" Java(TM) SE Runtime Environment (build 1.6.0_24-b07-334-10M3326) Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode) ~/Library/Java/Extensions is empty. /Library/Java/Extensions contains: libsvnjavahl-1.jnilib@ /System/Library/Java/Extensions contains: AppleScriptEngine.jar MRJToolkit.jar QTJava.zip dns_sd.jar jai_codec.jar jai_core.jar libAppleScriptEngine.jnilib* libQTJNative.jnilib* libShark.jnilib* libmlib_jai.jnilib* mlibwrapper_jai.jar Wait, looking for conflicting extensions brought me on the right track. I cleared the Java Webstart Cache with javaws -Xclearcache Now Gears.jnlp works. Sorry for bothering you.
This is actually good -- I didn't know about "javaws -Xclearcache". I'll put that on the wiki to help others in the future.
