JavaWeb java.lang.NoClassDefFoundError: sun/security/ssl/HelloExtension

I'm getting an error when trying to use a JavaWeb project using Glassfish 5.0. Everytime it tries to bring data from my SQL Database it gives me this error. <br>
StandardWrapperValve[ListadoPersonas]: Servlet.service() for servlet ListadoPersonas threw exception
java.lang.NoClassDefFoundError: sun/security/ssl/HelloExtension

Here is the servlet ListadoEstadosCiviles where I call the function which brings the data back from my database

GestorPersonas g = new GestorPersonas();
ArrayList<EstadoCivil> lista = g.obtenerEstadosCiviles();
for (EstadoCivil estadoCivil : lista) {
    out.println("<tr><td>" + estadoCivil.getId() + "</td><td>" + estadoCivil.getNombre() + "</td></tr>");
}

Here is GestorPersonas() constructor:

 public GestorPersonas() {
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        } catch (ClassNotFoundException ex) {
            Logger.getLogger(GestorPersonas.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

Here is obtenerEstadosCiviles() method

public ArrayList<EstadoCivil> obtenerEstadosCiviles() {
    ArrayList<EstadoCivil> lista = new ArrayList<>();
    
    try {
        Connection conn = DriverManager.getConnection(CONN,USER,PASS);
        Statement st = conn.createStatement();
        ResultSet rs = st.executeQuery("select * from EstadosCiviles");
        // Si el select devuelve una única fila, en lugar de while, se usa un if
        while (rs.next()) {
            int id = rs.getInt("id");
            String nombre = rs.getString("nombre");
            EstadoCivil ec = new EstadoCivil(id, nombre);
            lista.add(ec);
        }
        
        rs.close();
        st.close();
        conn.close();
    } catch (SQLException ex) {
        Logger.getLogger(GestorPersonas.class.getName()).log(Level.SEVERE, null, ex);
    }
    
    return lista;
}

I have no problem connecting my java application to sql, I think the problem is with glassfish but i cant figure out why it is not working

This is the servlet that is calling obtenerEstadosCiviles() function, I expect that table full with data

What I expect:

UPDATE

I've just checked my plugins and it appears that Java Web and EE it´s activated but the "Active" symbol doesnt appears active. Could this be part of the problem?

Had basically the same problem, eventually solved it with this solution here.

In your glassfish folder go to glassfish5/glassfish/modules/endorsed/ and open the grizzly-npn-bootstrap.jar file with winrar or your preferred unzipper.

Delete the sun folder and try running your program again.
