Run your app from terminal so that you can see the error logs

B4X:

# cd to Reserveren.jar path
cd /path/to
java -jar Reserveren.jar

This may be caused by 'Updres.jar' path is not found. This may be solved by providing the absolute path.

B4X:

shel2.Initialize("shel2", "java", Array As String("-jar", "/path/to/Updres.jar"))

Thank you for the quick response billzhan.
I tried to start it in the terminal.
No respons.

Have now tried:
shel2.Initialize("shel2", "java", Array As String("-jar", File.DirApp&"/Updres.jar"))
File.DirApp displays the correct path.
And I still get the same error.

Try to use the full path to java. Maybe the default Java is set incorrectly.

What happens when you run "java -jar Updres.jar" from the terminal?

Note that you should use File.Combine (File.DirApp, "Updres.jar")

Terminal:
# cd Documenten
# cd Faunatuurlijk
# cd Reserveren
# cd Objects
# java -jar Updres.jar
And nothing happened.

and if I do the following without #
java -jar Updres.jar
Unable to access jarfile Updres.jar

shel2.Initialize("shel2", "java", Array As String("-jar", File.Combine (File.DirApp, "Updres.jar") ))
And still have the same problem.

Terminal:
# cd Documenten
# cd Faunatuurlijk
# cd Reserveren
# cd Objects
I tried it again
open java -jar Updres.jar
The files /User/jackbodewes/java and /User/jackbodewes/Updres.jar do not exist.

What're the outputs ( terminal ) :

B4X:

java -version

id -F

pwd

# given that the path is ~/Documenten/Faunatuurlijk/Reserveren/Objects
ls -l ~/Documenten/Faunatuurlijk/Reserveren/Objects
ls -l ~/Documenten/Faunatuurlijk/Reserveren/Objects/Updres.jar
ls -l ~/Documenten/Faunatuurlijk/Reserveren/Objects/Reserveren.jar

Java 8u40+ is needed for B4J 4.20. You don't have Java8 installed/set

Yes we did it.
You were right with the Java version 1.6.0.65
But I had to reinstall the entire SDK and not just install the java update 1.8.
Thank you very much billzhan and Erel.
