title: "PrintWriter" is not recognized by eclipse
body: <p>I have Eclipse(Kepler) IDE and when I write the below code.</p>
  
  <pre><code>PrintWriter pw=response.getWriter();
  </code></pre>
  
  <p>It displays an error message saying that PrintWriter cannot be resolved to type. The import statements that I have used are as follows,</p>
  
  <pre><code>import java.io.IOException;
  import javax.servlet.ServletException;
  import javax.servlet.annotation.WebServlet;
  import javax.servlet.http.HttpServlet;
  import javax.servlet.http.HttpServletRequest;
  import javax.servlet.http.HttpServletResponse;
  import javax.servlet.http.*;
  </code></pre>
  
  <p>Do I have to import some additional statements to get my PrintWriter to work? If yes then which are they?</p>
  
  <p>Thanks in advance :)</p>
