On one machine - Windows 10 running Virtual Box in which Linux Mint 18.3 Xfce runs - the app worked perfectly first time. Just like it did (and always has done) in Windows. No requirement for the user to fiddle with subsidiary apps, or file permissions or anything like that. Superb. Mission accomplished.
One a different machine - Windows 10 running Virtual Box in which Linux Mint 19 Xfce runs - the app simply doesn't run. See "Mechanics" below for details.
In both instances of Linux Mint, the basic user config is the same, i.e. the non-admin user wants to run this Java app. The browser in both cases is Chromium.
Is there a checklist of dependencies for a normal user (not a techno geek!) to check whether the Linux instance is correctly configured?
This relates to the instance in which ProRealTime doesn't work.
- ProRealTime downloads a jnlp file, which the (non-admin) user needs to
- Although the website intends to run the program directly (in Windows and in the Linux instance that works), in this instance the user needs to use Thunar to right-click and open with Iced Team web start.
- The program then appears to launch normally, but then ends up with a java dialogue box as below:
Code: Select all
net.sourceforge.jnlp.LaunchException: Fatal: Launch Error: Could not launch JNLP file. The application has not been initialized, for more information execute javaws/browser from the command line and send a bug report. at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:582) at net.sourceforge.jnlp.Launcher$TgThread.run(Launcher.java:945) Caused by: java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:576) ... 1 more Caused by: java.lang.NoSuchMethodError: java.lang.SecurityManager.checkTopLevelWindow(Ljava/lang/Object;)Z at obs.wG.mT(obs:1800) at obs.wG.<init>(obs:688) at com.itfinance.core.Starter.nM(obs:201) at com.itfinance.core.Starter.startAppli(obs:530) at com.itfinance.core.Starter.main(obs:165) ... 6 more
The details are:
- when attempting to launch the browser - terminal >
javaws -browser- the following error appears: ... subsequent to which a browser appears, but is functionally useless.
- then I have no idea what to do next!
