Http delete 403 error tomcat

From my Android application, I am trying to delete an image that is stored in the tomcat webapps directory. When I try the following code, it gives me the status code 403. I looked online and found that it gives this code if the request is legal, but the action is prohibited. Can someone tell me where I am going wrong. My code is:

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("DELETE");
int responseCode = connection.getResponseCode();

and when I tried using HttpClient, it gave me the same error: HTTP / 1.1 403 Forbidden

HttpClient httpClient = new DefaultHttpClient();
                  try {
                    httpClient.getParams().setParameter(
                            "http.socket.timeout", new Integer(90000));
                    HttpDelete delete = new HttpDelete(new URI(
                            "http://192.168.2.1:9090/LocationUpdaterServlet/images/"
                                    + userid));
                    Toast.makeText(Image.this, "Removing your picture", 5000).show();
                    HttpResponse response = httpClient.execute(delete);
                    if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
                        System.out.println(response.getStatusLine());
                    } else {
                        // Here every thing is fine.
                    }
                    HttpEntity resEntity = response.getEntity();
                    if (resEntity == null)
                        System.out
                                .println("---------Error No Response !!!-----");
                }catch (Exception ex) {
                    System.out.println("---------Error----"+ ex.getMessage());
                    ex.printStackTrace();
                } finally {
                    httpClient.getConnectionManager().shutdown();

                }

In web.xml, include other http methods with this:

<servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
    <init-param>
        <param-name>debug</param-name>
        <param-value>0</param-value>
    </init-param>
    <init-param>
        <param-name>listings</param-name>
        <param-value>false</param-value>
    </init-param>
    <init-param>
        <param-name>readonly</param-name>
        <param-value>false</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

Parameters debugand listingsare loaded by default in tomcat, and by default readonly- true, which means that only GET and POST are available.

Other options available:

     debug               Debugging detail level for messages logged
