Thanks Karsten

Did you forget to upload the jnlp.txt files?

Please attach the log files that are created when you run the Jnlp using OWS. The above log is for the itw-settings app used to configure OWS deployment properties. I requested you to attach the log files. not copy them. You can zip the log files and attach to your post. It is difficult to read and...

Hi Carmello, I found more information: The optional install attribute can be used in a shortcut element to describe the application's preference for being considered "installed". If the value is "true" the application prefers to be considered installed. The default value of the i...

Hi Carmello, As I said earlier, one of the options for this property is "Install If Hinted". So the question is where do you specify this hint? For shortcuts, a hint can be specified in the Jnlp file using the <shortcut> tag under <information> tag. So I am wondering if there is a similar ...

Hello Carmello, As far as I can tell from my search in the code OWS and ITW do not support deployment.javaws.install property. However can you please elaborate a bit how you are using this property? For instance Java Control Panel > Advanced Tab has Application Installation. It has options like Inst...

There is a bug in OWS 1.4.0 such that it is not able to handle jar file names like javafx-controls-17-ea+16-win.jar . Character + in ea+16 is problematic. It results in the following error: Error while activating jars java.io.FileNotFoundException: <path>\s_javafx-controls-17-ea 16-win.jar The worka...

It seems that the App with WebView was crashing on loading a URL because of bug OpenJfx. 11.0.2 to 16. This bug has been fixed in OpenJfx v 17-ea+16.:So one can specify those jars in the jnlp file: <?xml version="1.0" encoding="utf-8"?> <jnlp spec="1.0+"> <information> ...

An App that uses JavaFX WebView from OpenJfx when started with OWS, crashes as soon as a URL is loaded in the. WebView. The JRE used to run the App is Java 11 or higher. The OpneJfx lib versions tried were 11.0.2, and also 16. Jnlp file: (Note that s_ prefix means signed jar) <?xml version="1.0...

Hi Muhammad, I do not know why your app jnlp is not running when started locally but runs when deployed on server. However, I can start the same app (after I built it in my set up) both locally as well as by deploying on server. I am attaching a zip file. It has jars and fxapp.jnlp. You can unzip an...

I am able to run your app after building it using your run.bat and by deploying it in a server. Running from command line like you do in the run.bat file where jnlp and jar files are local (not on server) I get the following. Caused by: java.lang.NoClassDefFoundError: javafx/application/Application. .

Differences I noted between your sample and mine :

Jnlp file:
Manifest of Jar file:

I am able to run your app. I compiled it with Java 8, created a jar, signed it. I chose OWS to use AdoptOpen Java 11 to run the ToggleButtonDemo app: <?xml version="1.0" encoding="utf-8"?> <jnlp spec="1.0+" codebase="http://localhost:8080/jnlp"> <information> ...

Note: When running with Java 11+ the JavaFX Application is required to be launched via a launcher class: // Launcher for JavaFX application which is specified in the Jnlp file public class HelloWorld11Launcher { public static void main(String[] args) { HelloWorld11.main(args); } } // JavaFX Applicat...

Please answer all the questions I asked you in the earlier post.

Hi, I had a look at the logs. In the Stage2 log there is an exception: 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.sour...
