B4J Question Error when trying to run UI application that connects to jRDC2

[vfafou]

Hello!
I'm trying to run a UI application with executable created with integrated B4J packager.
When I double click to run the .exe my initial form is instantly drawed on the screen and closes immediately!
Running the run_debug.bat I have the following error:

Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.
httputils2service._service_create (java line: -1)

Thank you in advance!

Which version of Java are you using?

 

[vfafou]

Open JDK 11.0.1 downloaded from B4X.

 

[Erel]

Something is misconfigured. Are you using latest version of B4J?

 

[vfafou]

Yes, I do!

 

[Erel]

Reproduce it in a small project and upload it.

Hello, Erel!

This is a cut from my project without any additional libraries except jMetro.
If you make a Standalone Package and run the run_debug.bat, you will see the exception from my first post and the exceptions for jMetro from my other thread:

jMetro Style CSS

Hello! I'm using the jMetro style CSS as described here: https://www.b4x.com/android/forum/threads/javafx-metro-style-css.114932/ It's working perfectly but when I try to run the standalone package made with embeded packager, I have the following error: Oct 31, 2021 9:59:14 PM...

I have attached the jMetro library too!

Thank you in advance!

I ran you project in debug mode and it fails because You aren't calling stockUtils.Initialize.

For further discussion upload a new project with only the relevant feature.

 

[vfafou]

Oh! I'm really sorry!
I accidentally removed the stockUtils initialization from the demo!
The same error is appeared when I have it initialized.
It is initialized at addPages into B4XMainPage.

UPDATE!!!

I've found that running the jar with java.exe with the following args, the app is running perfectly!

java --module-path "C:\java\11.0.1\javafx\lib" --add-modules=javafx.controls -jar "C:\dev\B4X\Projects\Zooland 0.9\B4J\Objects\Zooland.jar"

How to configure packager call java with these args?

 

[vfafou]

Hello!
Is it possible to configure the packager to call java with these args?
Thank you in advance!

 

[Erel]

javafx.controls is included by default. As I wrote:
