B4J Question smartcardio class not found Exception

[Hengki]

Hi all,
I want to ask and ask for advice, I'm trying to make a small application to get a list of smartcard readers, after I try to compile (debug and release) it works, the list of smartcard readers appears, but if I build a standalone package form the application only appears briefly then disappears , when I checked there was an error ( java.lang.ClassNotFoundException: javax$smartcardio$TerminalFactory)
My question is, are there still deficiencies in making packages and what should be added, please advise.
thank you

Where is your #AdditionalJar directive? Looks like you are using a jar but not included in your project?

 

[EnriqueGonzalez]

the packager usually nees some extra configuration to recognize some jars, classes and modules

look here:

Integrated B4JPackager11 - The simple way to distribute standalone UI apps

B4JPackager11 is a utility written in B4J that uses the underlying Java tools to create a standalone package that doesn't depend on any other software being installed. It works with OpenJDK 11 and OpenJDK 14. Starting from B4J v8.30 it is integrated in the IDE and available under Project - Build...

www.b4x.com

there are examples for webview, poi, ssl. so on and so forth.
Try experimenting with exports and opens directives.

is that or you are indeed not linking the libraries look for the directve: #merge libraries

I think smartcardio doesn't need extra jar, because java already provides it

I have tried using b4j package 11 , but it still doesn't work, the error is still the same
