B4J Question How can I start the app on Desktop

[Sinan Tuzcu]

Hi guys,

is it possible, to run the app on the Desktop?
I try since yesterday to run the application,, but doesn't work.
I click on the jar file and the mouse cursor rotate but nothing will open and I get also not error message.

I have install the latest version of Java how it is described on the webpage.

We need some more information before we can give you a proper answer. Which version of Java did you install? It's different for Java 8 and Java 11.

I have took this link from here--> OpenJDK 11 + OpenJFX 11: download link.
I think it is the version 11.

Ok, to run a java app from the desktop in java 11 you need to create an exe file that contains the JRE (Java Runtime Environment) using B4JPackager11.

For Java 8 the JRE is installed on the PC and will run a Jar file.

B4JPackager 11 is indeed the way to build a standalone package.

For Java 8 the JRE is installed on the PC and will run a Jar file.

Not always the case. The real difference is that if Java 8 is installed on the computer then you can run apps by double clicking on the compiled jar.
Starting from Java 11, JavaFX is not included in the JRE so executable jars cannot run without some configuration.
