Printing UTF8 extended characters in servlet ( Solved) [on hold]

I try this code and it works very well:

package code;



    public class TestClass
    {
        public static String myName="محمد mohammed";


        public static String getMyName()
        {
            return myName;
        }
        public static void main(String[] args) 
        {
            System.out.println(getMyName());
        }

    }

and I get this result :

محمد mohammed

But when I try to call from servlet in same package and project :

    protected void doGet(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException
    {

...
System.out.println(TestClass.getMyName());          
...
    }// END DO GET

I got this result:

???? mohammed

Moreover, I tried to print directly from the servlet and I got '?' for any Arabic letter.

Note: In two files I use : UTF-8

It is solved by changing server encoding. see below:

Go to (if use Eclipse): 1- Servers. 2- open the server. 3- find : open lunch configuration then open it. 4- Go to Common. 5- Change Encoding.
