B4J Question Non-UI application installation

[CR95]

In order to understand how to install my "Console Non-UI" application in a LINUX environment, I loaded and installed the "curl" sample of this old thread :

Non-UI Applications

B4J currently supports two types of applications: UI applications (based on JavaFX) and Non-UI applications. Non-UI applications are standard Java applications. Usually the input to such applications is with command line arguments. You should create a new project and select: The program...

I an running Windows 7 and JAVA is installed
I follow the process of the thread (java -cp <jar file> <package>.main <args>) and I got this error:

In a second time, I searchd in the forum, I found :
Non-UI applications will run with a double click on the compiled jar if Java is installed.
When I double clicked on "curl.jar", a cmd window opens briefly and then disappears but my file wasn't executed.
After searching on the Web, I also tried
java.exe –jar curl.jar
First time, I got the message "URL is missing" which comes from curl application when there is no argument
So I tried
java.exe –jar curl.jar http://www.example.com
and I got the error message :
could not find or load main class ?jar (note that the end is different that the first try)

Please could you tell me what is the good process forexecuting a non-UI application :
- under Windows
- in a second time, under Linux-Ubuntu (without B4A Bridge installed)

It should be java -jar yourjar.jar

Yes. Your command works in Windows/Java environment. Thanks

Please could you tell me how it would be possible to build a package with my jar file and all the necessary files (Java, I presume) in order to run on a LINUX system WITHOUT Java installed (something similar to the package which is built by B4J Packager) ?

There is no packager tool for non-ui apps. You can copy OpenJDK or the JRE version together with your app.
