Using Cookies for Session Maintenance gives output Hello72EB80AEBFB7831A35879408414F9ABA

I am making a small program where user's name will be used all over the pages where he navigates. I have written following code.

JSP file:

<form action="CookieServletOne" method="post">
User Name:<input type="text" name="username">
<input type="submit" value="Go">
</form>

Servlet One (under post method):

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

        String username=request.getParameter("username");
        pw.println("Welcome " +username);

        Cookie ck=new Cookie("un",username);
        response.addCookie(ck);

        pw.print("<form action='CookieServletTwo'>"); 
        pw.print("<input type='submit' value='go'>"); 
        pw.print("</form>"); 

        pw.close();

Servlet2:

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

    Cookie[] ck=request.getCookies();
    pw.write("Hello" +ck[0].getValue());

I want to take the value which is written in text box to the Servlet2 by using cookies. But,

At the end it is printing value something like this:

Hello5BD0268F522455DA719130360F74A969

What I am doing wrong here ???

Server: Apache Tomcat. Jdk: 1.7 Os: lubuntu.

Thanks.

You should be adding below code to your servlet2 to get your desired result.The output which you are getting is JSESSIONID.

Cookie[] ck=request.getCookies();
for(int i=0; i<ck.length; i++) {
    if("un".equals(ck[i].getName())) {
        pw.write("Hello" +ck[i].getValue());
    }
}
