Answer 1

You can use this command

set MAVEN_OPTS= -Duser.language=tr

Anyway the best solution is to put these informations in the POM file and never by command line. In particular you have to deal with the configuration of Maven-Surefire-Plugin

    
        org.apache.maven.plugins
        maven-surefire-plugin
        2.9
        
            
                tr
                TR
            
         
    

Second Question: Another question if I may, I am running a web app in my locale but it supports lets say german, english.. And your system locale is DE. Can I get your system locale from your request? Or maybe the language you prefer by your browser?

You can take these informations from the request. Here is an example in a servlet.

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.Locale;

public class GetLocale extends HttpServlet{

  public void doGet(HttpServletRequest request,HttpServletResponse response)throws ServletException, IOException
  {
      Locale locale = request.getLocale();
      String language = locale.getLanguage();
      String country = locale.getCountry();

      response.setContentType("text/html");
      PrintWriter out = response.getWriter();

      out.println(language + ":" + country);
  }
}
