问题 I am now trying to deploy a Java application with Java Web Start. The application works fine when running standalone. I exported the project as a runnable .jar file, and then wrote the corresponding jnlp file. However, when running from the jnlp file, the application returns the following error when starting up: Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: someClass ........ Caused by: java.lang.ClassNotFoundException: someClass ......... I exported the .jar file

问题 I am trying to remote debug a Java applet, but I cannot seem to get the -agentlib:jdwp JVM argument to work. I have tried specifying it in the Java control panel for the particular JRE used, and I have tried setting it via the JNLP file used to launch the applet. What is the correct way to set JVM parameters for applet launch? In particular, to debug remotely. 回答1: Looking at a similar SO question, I found the following answer... Sometimes to debug some security related stuff the browser

问题 It is years since I have worked in Java (that's my excuse). I am trying to launch a Java Swing UI as an Applet (previously done via Web Start). I have modified the jnlp file to reflect the changes that I know are necessary for an applet (e.g. using applet-desc instead of application-desc). Inside the <resources> tag in the jnlp file we set system properties like this: <property name="java.security.auth.login.config" value="$$context/app/auth.conf"/> In the init method of the main class we try

问题 I want to configure my webstart app/jnlp so that if no internet connection is available, it would start from cache. Nevertheless, when I disconnect from the internet, I always get a NoRouteToHostException or UnknownHostException exception, despite the configuration below. I've set the offline-allowed and update tags/attributes properly I think; I cannot find the reason why webstart is still trying to lookup the host. I definitely do have the app cached from my previous start when I was

问题 I have a jnlp file for deploying my javafx 2.0 application, however, how do I make sure that the users have the correct javafx runtime (32 or 64 bit depending on the jvm present on the machine) and if not, download it and run the application. Assuming that the user does not have a javafx runtime currently installed, the problems that I'm facing mostly with a 64 bit machine with either 32-bit, 64-bit or both JRE's are: 1) The Javafx swing deployment guide mentions to use the <jfx:javafx

问题 On Mac OS X 10.9 signed Java Web Start applications are blocked by default with the message: "application.jnlp" can't be opened because it is from an unidentified developer. I know it's possible to weaken the security checks to allow any application to run, but that requires a manual intervention of the end user. Is it possible to "sign" a Java Web Start application such that it is recognized as originating from an identified developer? Thank you 回答1: Apple does appear to support signing of

问题 After the JNLP gets downloaded in the browser it becomes cached so it doesn't need to be downloaded again, which is good. However, as a consequence, if I update the JAR that the JNLP uses, users will still see the old version of the app that is in the cache. You can clear the cache by running this in the terminal: javaws -uninstall But obviously you could not expect from users to run this when your update is ready. It should be more seamless than that. One idea is to change the jnlp file name

问题 Issue I have a preloader for my application that handles the Application-specific initialization. Now I'm trying to extend this so that the preloader also shows the progress of the downloaded application JARs. TL;DR Why is the preloader not getting loaded during Phase 2 , as this should handle the PreloaderFx::handleProgressNotification(); to track the downloading of the JARs I suppose? Update 14 March 2016 : Is using DownloadServiceListener the way to solve this? How to connect this to a

问题 I want to have a link on my JSF page. When you click this link, a Java Web Start application starts. The application doesnt affect the current page at all. The application just starts on its own. The problem is, I the JNLP file that starts the Java Web Start application needs to be generated on the fly. Basically I will decide which application and what paramaters for the JNLP file depending on the state of the application. Does anyone know of a way that I can accomplish this. Is it possible
