B4J Question package javafx.application does not exist

[Olivier Zeegers]

Hello, I am trying to build a standalone version of my project via the B4J program.
For this I had to update my java from 8 to 22..
Now I get this error and already installed javaFx from GluonHQ and updated the conf path but still this error:

B4J Version: 10.00

Anyone knows the solution ?

The additional libraries path is not point to javafx folder.

You are using the wrong version of Java.

Best to download OpenJDK 19: https://www.b4x.com/android/forum/threads/b4a-v13-0-beta-is-available-for-download.162136/#content

If you've set up the folders correctly
just add

#JavaCompilerPath: 22, your/path/to/javac.exe

#JavaCompilerPath: 22, your/path/to/javac.exe

OK, when I add this I get this error output:

Thank you Erel,

I have downloaded this version and pointed the path to C:\Program Files\Java\jdk-19.0.2\bin\javac.exe
But I get the same error as in my reply to Daestrum...

Do not place it into Program Files folder.
It's a system restricted folder.
Make something like
C:\Java

Obviously, if you downloaded the jdk19 is correct, you forgot to remove this JavaCompilerPath.

OK, I moved java to C:\Java and now everything works !

it generates a results.exe in the temp/build folder but when I run it nothing happens ?

where can i find documentation on the create standalone package ?

thanx

Run run_debug.bat to see error log

Did you run the EXE from inside the folder or did you took it out from the folder?
In order to work it must be executed from inside that folder.
And you have to distribute the entire BUILD folder to other user.
Just use Build Standalone Package from the Project menù to create it.

This is the Build folder...
But when I click on result.exe nothing happens ;-)

Run run_debug.bat to see error log

OK, yes I see that files are missing in the bin folder ! thanx

 

[Olivier Zeegers]

OK, I copied all external images and sound files to the bin folder and it works !!

thanx everyone for the help !

Here I am once again:

I managed to create a standalone EXE file for my MAIN application... This runs smoothly...

But I created another application that is supposed to manage the settings of the main app.. I also created a standalone version and put the .EXE in the same folder as the main app but by clicking of the managing app it opens the main app... I suppose the .EXE is only pointing to another file with the same name ?

How can I accomplish to run both application separate from each other but simultaneously ?


thank you !
