you have not written the form method here 

out.print("<form action='servlet2'>");  
    out.print("<input type='submit' value='go'>");  
    out.print("</form>");

so by default it will be get.So you need to call the doGet() of second servlet or write form method as post like this out.print("<form action='servlet2' method='post'>");
