To clarify for people not familiar with Pedagogic Steps: the pedagogica scripts are stored in a jar file. It is this jar file that Geoff is referring to above.
This is one example of resources needed by an otml file. Images are another example. Currently, we put those resources on a webserver. If you are using Roolo to store the content then you'll want to store those resources in the repository. How those resources are accessed at runtime is not clear. That is what we were were talking about at a previous sail meeting. I think the best way to start is to provide web access to the resources in the repository, and then put these urls in the otml file. OTrunk currently supports a few options for accessing binary resources: - store the resources on a webserver and use absolute urls to them. - store the resources on the same webserver as the otml file, and use urls relative to the otml file. (the context url or codebase of the otml file can also be overridden using a property in the otml file). - store the resources directly in the otml file as gzipped-base64ed strings. - put the otml file and the resources in a jar file, use relative urls in the otml file, and put the jar file on the classpath. It would be easy to add another option where OTrunk could be passed a url to a zip file that contained the otml file and its resources. This is slightly different than the last option above which requires the jar file to be on the classpath. > > > I can't run the JNLP at the url http://itsidiy.concord.org/models/2. > It gives me this "Unable to launch the application" error, the stack > trace is below. Do I need to install something? This looks like the very annoying bug we found in java 6. The only solution we've found to this problem is to clear the cache. The problem started after we moved jnlp.concord.org to a new server with a different IP address. So we believe this problem is because webstart is storing the server's IP address in its cache. > > java.lang.NullPointerException > at > com.sun.deploy.net.DownloadEngine.applyPatch(DownloadEngine.java:607) > at > com.sun.deploy.cache.CacheEntry.processTempDataFile(CacheEntry.java:645) > at com.sun.deploy.cache.Cache.downloadResourceToCache(Cache.java:500) > at > com.sun.deploy.net.DownloadEngine.actionDownload(DownloadEngine.java:947) > at > com.sun.deploy.net.DownloadEngine.getCacheEntry(DownloadEngine.java:1059) > at > com.sun.deploy.net.DownloadEngine.getResourceCacheEntry(DownloadEngine.java:1134) > at > com.sun.deploy.net.DownloadEngine.getResourceCacheEntry(DownloadEngine.java:1068) > at > com.sun.deploy.net.DownloadEngine.getResource(DownloadEngine.java:142) > at > com.sun.javaws.LaunchDownload.downloadJarFiles(LaunchDownload.java:826) > at > com.sun.javaws.LaunchDownload.downloadEagerorAll(LaunchDownload.java:742) > at com.sun.javaws.Launcher.downloadResources(Launcher.java:1165) > at com.sun.javaws.Launcher.prepareLaunchFile(Launcher.java:540) > at com.sun.javaws.Launcher.prepareToLaunch(Launcher.java:157) > at com.sun.javaws.Launcher.launch(Launcher.java:95) > at com.sun.javaws.Main.launchApp(Main.java:302) > at com.sun.javaws.Main.continueInSecureThread(Main.java:212) > at com.sun.javaws.Main$1.run(Main.java:107) > at java.lang.Thread.run(Thread.java:613) > > > Thanks, > Geoff > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "SAIL-Dev" group.
