How to go to previous page upon clicking the cancel button

This is my web.xml

           <?xml version="1.0" encoding="UTF-8"?>
           <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org  /xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID"version="3.1">

          <welcome-file>index.htm</welcome-file>
          <welcome-file>index.jsp</welcome-file>
          <welcome-file>default.html</welcome-file>
          <welcome-file>default.htm</welcome-file>
          <welcome-file>default.jsp</welcome-file>
          </welcome-file-list>
          <servlet>
          <servlet-name>Jersey Webapp Application</servlet-name>
          <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

          <init-param>
          <param-name>com.sun.jersey.config.property.packages</param-name>
          <param-value>com.restify.frontend;org.codehaus.jackson.jaxrs</param-value>
          </init-param>
          <init-param>
          <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
          <param-value>true</param-value>
          </init-param>
          <load-on-startup>1</load-on-startup>
          </servlet>
          <servlet-mapping>
          <servlet-name>Jersey Webapp Application</servlet-name>
          <url-pattern>/reporter/*</url-pattern>
          </servlet-mapping>
          </web-app>

Here is my 1st servlet:Name of servlet:Response

              @WebServlet({ "/Response", "/reportsto" })
              public class Response extends HttpServlet {
              private static final long serialVersionUID = 1L;
              protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
              .....

My 2nd servlet i.e Response1:

              @WebServlet({ "/Response1", "/resp" })
              public class Response1 extends HttpServlet {
              private static final long serialVersionUID = 1L;
              protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        .....               
              Set<Map.Entry<Object,Object>> s2=map1.entrySet();
              PrintWriter out1=response.getWriter();
              out1.println("<html>"+
              "<form action=\"./reportsto\" method=\"get\">"+
              "<input type=\"cancel\" value=\"cancel\" name=\"cancel\">\n\">"+
        "</form>"+);
      So from the servlet Response1 I need to goto the previous page that is   servlet1 Response onclicking the cancel button.How can this be done please advice.

Actually my servlet1 Response will give the output as:

                 Number User Id     Username    Count
                   1    A12354      Anagha R        0
                   2    M12345      Madhusudan S    1

My second servlet Response1 displays:

                   1    CHARgska    Validating

Here In servlet2 I need to have a cancel button upon clicking takes me back to the previous page i.e servlet1

   <script>
    function goPrev() {
          window.history.back();
    }
    </script>

and call this function in input tag

<input onclick="goPrev()" type="....>

The click of Cancel button will take the user to the previously visited page. 

out1.println("<html>"+
              "<form action=\"./reportsto\" method=\"get\">"+
              "<input onclick=\"window.history.go(-1); return false;\" type=\"button\" value=\"Cancel\" />"+
        "</form>"+);
