Change Glassfish Servlet Encoding/Charset

I'm sending a Serializable object to Servlet on Glassfish 4.1 server, the object has String fields with Arabic chars, when I try to log the Arabic values I got (?????)

I've read This and This and many other posts but nothing solved the problem, I've tried the same codes on Tomcat 8 Server and it works fine

What should I do with Glassfish server or my Servlet to read UTF-8 chars correctly?

Sending the Serializable object:

        url = new URL(ServerInfo.STORABLE_RECEIVER_URL);            
        http = (HttpURLConnection) url.openConnection();
        http.setRequestProperty("content-type", "application/x-object;  charset=utf-8");
        http.setRequestProperty("Accept-Charset", "UTF-8");
        http.setDoOutput(true);
        http.setDoInput(true);          
        out = new ObjectOutputStream(http.getOutputStream());
        out.writeObject(t);

web.xml

<filter>
    <filter-name>Set Response Character Encoding</filter-name>
    <filter-class>net.abdullahcodes.serv.MyFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>Set Response Character Encoding</filter-name>
    <url-pattern>/TradableReceiver</url-pattern>
    <url-pattern>/*</url-pattern>
    <url-pattern>/</url-pattern>
</filter-mapping>

<locale-encoding-mapping-list>

        <locale>ar</locale>
        <encoding>UTF-8</encoding>
    </locale-encoding-mapping>

Servlet test received Serializable object:

        log("sys: "+System.getProperty("file.encoding"));
        log("def: "+Charset.defaultCharset());
        log("size: "+b.totalRowsCount()+", "+b.totalColumnsCount());
        log("test arabic: هلوووووووووويااا");
        System.out.println("test sysout: اوووه خطبها نصيب");
        while (b.hasNext()) {
            Position p = new Position();
            p.setEn(b.next());
            p.setAr(b.next());
            log("p: "+p.toString());                
        }

Console output on Glassfish:

You need to set the command line property:

 -Dfile.encoding=UTF-8

when starting Glassfish.

If you're starting from your IDE then you need to add this setting to the launch configuration.

If Glassfish is being started as a service then you need to set an environment variable:

 JAVA_TOOL_OPTIONS=-Dfile.encoding=UTF-8
