JavaFX deployment: Failed to launch JVM - javafx

Question

Greetings
I have deployed a simple JavaFX application using msi installer that was created by jpackage. When double-clicking on the application icon installed in Windows 10 "program files" directory, it displays an error "Failed to launch JVM". Prior to deployment, I tested the application jar file from the command prompt without any problem. When checking the application installation directory (under "C:\Program files") it has all the runtime dlls and so on, so I am not sure what causes this error? Here is the japckage command I used to build the runtime image:
jpackage --type msi --name FileChooser -p "%JAVAFX_HOME%\lib;%M2_REPO%;org\openjfx\mavenfxfilechooser\mavenfxfilechooser.jar" --module "org.openjfx.mavenfxfilechooser/org.openjfx.mavenfxfilechooser.FileChooserApp"
Update
Following the recommendation given in the comment section, I installed the JMODS on my machine and issued a jpackage command line to point to the JMODS files instead of JAVAFX_HOME as follow:
jpackage --type msi --name FileChooser -p "%JMODS_HOME%;%M2_REPO%;C:\Users\hrh74\Downloads\Lib\file\org\openjfx\mavenfxfilechooser" --module "org.openjfx.mavenfxfilechooser/org.openjfx.mavenfxfilechooser.FileChooserApp"
I installed the application using the MSI runtime image and this certainly solved the" Failed to launch JVM" problem. The application started, however, I have a WebView component that should display content from https://us.yahoo.com when the user clicks on a "Yahoo" button and this doesn't seem to be working when the application run as a self-contained app but it works when I run the jar file from the command line. Do I need to add anything to the jpackage?
Please let me know if the source code and FXML file are needed.
Thanks

Your original problem has to do with missing native code. But you appear to have already solved that problem by using the JMOD files for JavaFX provided by Gluon. So I'll try to help solve your other issue regarding https://us.yahoo.com not loading in the WebView once you create a self-contained application.
When trying to load that website myself I was running into the same issue as you. Though sometimes I'd get a "we're working on the problem" page response, other times the entire application would become unresponsive, and yet other times nothing would happen (the load would just seem to fail "gracefully"). This happened with other websites as well, not just Yahoo. After some testing I was finally able to get the following error:
java.lang.Throwable: SSL handshake failed

That indicated to me the application created by jpackage was missing some crypto libraries. From here I just guessed, but inclulding:
--add-modules jdk.crypto.cryptoki,jdk.crypto.ec
When running jpackage seemed to solve the problem. I don't know if both modules are needed, or if only one is needed (or if adding either one implicitly adds the other).
Side note: When scrolling through https://us.yahoo.com I would frequently get the following warnings:
Mar 05, 2021 12:10:40 PM com.sun.javafx.webkit.prism.WCMediaPlayerImpl onError
WARNING: onError, errCode=0, msg=Could not create player!
And:
Mar 05, 2021 12:10:41 PM com.sun.javafx.webkit.prism.WCMediaPlayerImpl$CreateThread run
WARNING: CreateThread ERROR: java.lang.UnsupportedOperationException: Unsupported protocol "data"
I would get that warning regardless of how the application was packaged. I don't know how to solve the problem, or if there even is a solution without modifying the JavaFX code itself.

Have you seen running JavaFX application after jpackage? Try to download Gluon jmods and use it instead of %JAVAFX_HOME%
