PKCS11 Wildfly 13 - Digital certificate

I'm trying to use the following library: link

To use it, it is necessary to load a digital certificate, in this case, type A1.

When you try to use it with a normal class with a public static void main it works normally. I have a jar of my design that I use all the time.

It turns out that by using the library in a web project <package>war</package> and deploying in Wildfly(versão 13) , when trying to load the certificate: CertificadoService.certificadoPfx(path, pass);

Bursts this Exception:

Caused by: java.lang.NoClassDefFoundError: sun/security/pkcs11/wrapper/PKCS11Exception

Follow class:

@Singleton
public class Worker {

    private AtomicBoolean busy = new AtomicBoolean(false);

    public void work() {
        if (!busy.compareAndSet(false, true)) {
            return;
        }
        try {
            System.out.println("Executing this task at " + new SimpleDateFormat("HH:mm:ss").format(new Date()) + ".");

            String path = "/home/user/certificado.pfx";
            String pass = "4321";


            CertificadoService.certificadoPfx(path, pass);

        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            busy.set(false);
        }
    }
}
