B4J Question ZXing QR lib. problem with standalone package

[Mostez]

I'm using ZXing library to generate QR code on socket server page, the code runs OK in debug or release mode, but when I generate standalone package I get this error:
any ideas how to fix that?
TIA

Spoiler: Error

You need to add the packager properties

#PackagerProperty: AdditionalModuleInfoString = provides org.eclipse.jetty.io.ssl.ALPNProcessor.Server with org.eclipse.jetty.alpn.java.server.JDK9ServerALPNProcessor;
#PackagerProperty: AdditionalModuleInfoString = provides org.eclipse.jetty.http.HttpFieldPreEncoder with org.eclipse.jetty.http2.hpack.HpackFieldPreEncoder, org.eclipse.jetty.http.Http1FieldPreEncoder;
#PackagerProperty: AdditionalModuleInfoString = uses org.eclipse.jetty.util.security.CredentialProvider;
#PackagerProperty: AdditionalModuleInfoString = uses org.eclipse.jetty.io.ssl.ALPNProcessor.Server;
#PackagerProperty: IncludedModules = jdk.charsets, jdk.crypto.ec

You need to add the packager properties

I included these two properties already:

    #PackagerProperty: AdditionalModuleInfoString = uses org.eclipse.jetty.websocket.common.RemoteEndpointFactory;
    #PackagerProperty: IncludedModules = jdk.crypto.ec

then I included all of the properties you've recommended, I also modified the code according to @Erel's recommendations here, but still get the error

What version jserver are you using?

 

[Mostez]

What version jserver are you using?

3.00

 

[teddybear]

Try to upgrade jserver3 to 4.

 

[Mostez]

I just wonder it works ok in release and debug mode!

 

[aeric]

As mentioned by teddybear, you need to add:

#PackagerProperty: IncludedModules = jdk.charsets, jdk.crypto.ec

Don't miss the first module: jdk.charsets

 

[Mostez]

Don't miss the first module: jdk.charsets

Thank you so much @teddybear @aeric , that's solved the problem
