add an error message to panel in apache wicket

I have an apache wicket panel for google recaptcha where I integrate wicket with google recaptcha and everything is working as it should, but I need to add an error message or feedbackpanel I am not quite good with wicket, so please advise me what is the best solution for my case?
public class ReCaptchaPanel extends Panel {
private static final long serialVersionUID = -8346261172610929107L;
private static final Logger log = LoggerFactory.getLogger(ReCaptchaPanel.class);
final String publicKey = "6LdrIgceAAAAADWF-gIz_OHJg_5gLu7IVw11hTnt";
final String secretKey = "6LdrIgceAAAAAE9qxHViBj3Sl8uyqUVdluugPRTq";
final String scriptClassName = "data-sitekey";
final String recCaptchaClassName = "g-recaptcha";
String currentLanguage = getLocale().getLanguage();
String scriptValue = "https://www.google.com/recaptcha/api.js?hl=" + currentLanguage;
/* in the following link you can find the language codes
* https://developers.google.com/recaptcha/docs/language
* */
public ReCaptchaPanel(String id) {
super(id);
final IFeedbackMessageFilter feedbackFilter = new ContainerFeedbackMessageFilter(this);
final FeedbackPanel feedbackPanel = new FeedbackPanel("feedback", feedbackFilter);
feedbackPanel.setOutputMarkupId(true);
add(feedbackPanel);
add(new Label("reCaptchaComponent", "").add(new SimpleAttributeModifier("class", recCaptchaClassName))
.add(new SimpleAttributeModifier(scriptClassName, publicKey)));
add(new Label("reCaptchaScript", "").add(new SimpleAttributeModifier("src", scriptValue)));
}
public ReCaptchaPanel(String id, IModel model) {
super(id, model);
}
/**

*
* #param secretKey Secret key (key given for communication between arena and Google)
* #param response reCAPTCHA response from client side (g-recaptcha-response).
* #return true if validation successful, false otherwise.
*/
public synchronized boolean isCaptchaValid(String secretKey, String response) {
try {
String url = "https://www.google.com/recaptcha/api/siteverify",
params = "secret=" + secretKey + "&response=" + response;
HttpURLConnection http = (HttpURLConnection) new URL(url).openConnection();
http.setDoOutput(true);
http.setRequestMethod("POST");
http.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded; charset=UTF-8");
OutputStream out = http.getOutputStream();
out.write(params.getBytes(StandardCharsets.UTF_8));
out.flush();
out.close();
InputStream res = http.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(res, StandardCharsets.UTF_8));
StringBuilder sb = new StringBuilder();
int cp;
while ((cp = rd.read()) != -1) {
sb.append((char) cp);
}
JSONObject json = new JSONObject(sb.toString());
res.close();
log.info("Google ReCaptcha has been verified");
return json.getBoolean("success");
} catch (Exception e) {
e.printStackTrace();
}
log.error(" Google ReCaptcha failed");
return false;
}
public synchronized boolean isCaptchaValid() {
HttpServletRequest httpServletRequest = ApplicationBase.getHttpServletRequest();
assert httpServletRequest != null;
String response = httpServletRequest.getParameter("g-recaptcha-
response");
return isCaptchaValid(secretKey, response);
}
}
I use this panel in another wicket component ( form) ,
class FormEmail extends Form {
.........
final ReCaptchaPanel reCaptchaPanel = new ReCaptchaPanel("reCaptchaPanel") {
/**
* #see org.apache.wicket.Component#isVisible()
*/
#Override
public boolean isVisible() {
SessionBase session = (SessionBase) getSession();
ItemListPanelConfigParams configParams = new ItemListPanelConfigParams(session);
return configParams.isShowCaptcha();
}
};
add(reCaptchaPanel);
Button buttonSend = new Button("buttonSend") {
#Override
public void onSubmit() {
onSendCallback(emailRecipient, emailReplyTo, comment);
setResponsePage(callbackPage);
}
};
what i need to achieve is that add a message when the verify method in code above is false; I mean an error message, anyone knows how.

How to sent data from form to backend? [Java]

how to send data from the form view to the backend? I want to use the collected data to create a JSON request.
#Controller
public class ControllerClass {
Connect connect = new Connect();
#RequestMapping(value = "/Search", method = RequestMethod.GET)
public ModelAndView showForm() {
return new ModelAndView("Forms", "FlightDTO", new FlightDTO());
}
#RequestMapping(value = "/connect", method = RequestMethod.POST)
public String submit(#Valid #ModelAttribute("FlightDTO") FlightDTO flightDTO,
BindingResult result, ModelMap model) {
if (result.hasErrors()) {
return "error.jsp";
}
return connect.connect();
}
}
View class collecting data.

public class UrlBuilder extends FlightDTO {

"&currency=" + getCurrency() +
"&return_date=" + getDateTo() +
"&token=" + key;
return connectUrlString ;
}
}
I tried to solve my problem in many ways. Unfortunately to no avail, that's why I decided to create a thread. I could not find a similar problem. I was probably looking for a bad one. However, I do not know how to google
I get null response :
http://api.travelpayouts.com/v1/prices/cheap?origin=null&destination=null&depart_date=null&currency=null&return_date=null&token=47c5ebee552ce27c902e7521b6ef3858

Above code will not work as you are creating new UrlBuilder object which will not have any values instead of passing flightDTO object from the controller.
Controller
#RequestMapping(value = "/connect", method = RequestMethod.POST)
public String submit(#Valid #ModelAttribute("FlightDTO") FlightDTO flightDTO,
BindingResult result, ModelMap model) {
if (result.hasErrors()) {
return "error.jsp";
}
return connect.connect(flightDTO); //passing flightDTO object received from form
}
Connect
public String connect(FlightDTO flightDTO) { //Added new parameter to recevice flightDTO
String output = null;
try {
UrlBuilder urlBuilder = new UrlBuilder();
urlBuilder.setOrigin(flightDTO.getOrigin());
urlBuilder.setDestination(flightDTO.getDestination());
urlBuilder.setDateFrom(flightDTO.getDateFrom());
urlBuilder.setDateTo(flightDTO.getDateTo());
......//Set other required values
urlBuilder.ulr();
System.out.println("URL String : " + urlBuilder.ulr());
......//other code
}
}

Scribe-java and Woocommerce authentication

I'm trying to implement support for Woocommerce e-shop into our system and I'm using scribe-java for that. What I'm trying is to get Json response from e-shop and store it into database.
Problem is that I can connect to e-shop but instead of Json response, I get HTML response. Any help would be much appreciated. BTW, I'm using latest scribe-java 3.0.0
URL: http://shop_url/wp-json/wc/v1/orders?after=2016-08-17T00:00:00&page=1&per_page=100&order=asc
Here's source code:
private Integer callGETWithOAuthAuthentication(String url, StringBuffer sbRet) throws IOException {
OAuth10aService service = new ServiceBuilder()
.apiKey(getSettingsStr().getSecret1())
.apiSecret(getSettingsStr().getSecret2())
.debugStream(System.out)
.signatureType(SignatureType.QueryString)
.build(WooCommerceApi.instance());
OAuthRequest request = new OAuthRequest(Verb.GET, url, service);
service.signRequest( new OAuth1AccessToken("", ""), request);
Response response = request.send();
BufferedReader in = new BufferedReader(
new InputStreamReader(response.getStream()));
String inputLine;
StringBuffer responseJson = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
responseJson.append(inputLine);
}
if (sbRet != null) {
sbRet.append(responseJson.toString());
}
return response.getCode();
}
And here is WooCommerceApi
import com.github.scribejava.core.builder.api.DefaultApi10a;
import com.github.scribejava.core.model.OAuth1RequestToken;
import com.github.scribejava.core.model.Verb;
import com.github.scribejava.core.services.HMACSha1SignatureService;
import com.github.scribejava.core.services.SignatureService;
public class WooCommerceApi extends DefaultApi10a {
protected WooCommerceApi() {
}
private static class InstanceHolder {
private static final WooCommerceApi INSTANCE = new WooCommerceApi();
}
public static WooCommerceApi instance() {
return InstanceHolder.INSTANCE;
}
#Override
public String getAccessTokenEndpoint() {
return null;
}
#Override
public String getRequestTokenEndpoint() {
return null;
}
#Override
public Verb getAccessTokenVerb() {
return Verb.GET;
}
#Override
public Verb getRequestTokenVerb() {
return Verb.GET;
}
#Override
public String getAuthorizationUrl(OAuth1RequestToken requestToken) {
// TODO Auto-generated method stub
return null;
}
#Override
public SignatureService getSignatureService() {
return new HMACSha1SignatureService();
}
}
And this is a response I'm getting:
`<!DOCTYPE html>

HtmlViewService in OBIEE Web Service API is not rendering report (it's only showing spinning loader)

I have a Java application that leverages the OBIEE Web Service API to consume data from the BI Server. I am able to XMLViewService and the WebCatalogService just fine, but I can't quite get the HtmlViewService to properly render a report in the Java app. The report just shows the spinning loader, but never actually renders the report. I'm pretty sure it has to do with the fact that the Java app and the BI Server are on different domains. This is what the API documentation says:
In situations where Oracle BI Web Services and the third-party Web server do not belong to the same Domain Name Service (DNS) domain, users may get JavaScript errors related to browser security constraints for cross-domain scripting. To avoid these issues, use the setBridge() method to modify callback URLs to point to the third-party Web server. Be aware that a Web component executed by the third-party Web server to re-route requests to Oracle BI Web Services is not provided. This function would need to be fulfilled by the third-party application.
Several years ago, I did this same type of integration using .NET/C# and ran in the the same issue because the .NET app and the BI Server were on different domains. As a result, I had to create an HTTP Handler (.ashx file) as well as use the setBridge() method to to solve the issue.
The challenge that I'm having is that I can't find a servlet bridge example for Java. And I'm not too confident in porting the .NET/.ASHX code to a Java servlet/bridge. Does anyone have any code examples or direction they could provide to point me in the right direction? Here's a snippet of code to show you what I'm doing to pull back the report data:
// define report path
ReportRef reportRef = new ReportRef();
reportRef.setReportPath(reportFolder + "/" + reportName);
// set page params
StartPageParams pageParams = new StartPageParams();
pageParams.setDontUseHttpCookies(true);
// set report params
String pageId = htmlService.startPage(pageParams, sawSessionId);
String reportId = pageId + reportName;
htmlService.addReportToPage(pageId, reportId, reportRef, null, null, null, sawSessionId);
// get report html
StringBuffer reportHtml = new StringBuffer();
reportHtml.append(htmlService.getHtmlForReport(pageId, reportId, sawSessionId));
// return html
return reportHtml.toString();
This is the error that is coming back in the browser:
XMLHttpRequest cannot load http://myobiserver.com/analytics/saw.dll?ajaxGo. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://myjavaapp.com' is therefore not allowed access.

Using the BridgeServlet from link (http://pastebin.com/NibVnBLb) posted in previous answer did not work for us. In our web portal, embedding Oracle BI dashboard using BridgeServlet above, redirected us to OBI login page and console log showed incorrect resources(js/css) web links (local URL instead of OBIEE URL's).
Instead we used this class (with some minor adjustments) https://gist.github.com/rafaeltuelho/9376341#file-obieehttpservletbridge-java.

Pass values from javascript to Servlet [duplicate]

This question already has answers here:
How should I use servlets and Ajax?
(7 answers)
Closed 6 years ago.
I'm new bee working on passing below data from jquery to Servlet. Below are my files
javascript:
<script type="text/javascript">
function getData(tableName)
{
var tableId =tableName+"Table";
jsonObj = [];
$(\'#' + tableId + '\').find(\'tbody>tr\').each(function (i) {
var $tds = $(this).find('td'), setvilId = $tds.eq(1).text(),setvilNotes = $tds.eq(8).text();
item = {};
item["id"] = setvilId;
item["notes"] = setvilNotes;
jsonObj.push(item);
});
console.log(jsonObj);
var jsonString =JSON.stringify(jsonObj);
request(jsonString);
};
</script>
<script type=\"text/javascript\">
function updateNotes () {
var editable = true;
var editables = $('td[id*=notestd], td[id*=eta]');
editables.attr('contentEditable', editable);
}
function request(jsonString) {
$.ajax({
url: "/updatesetvil",
type: "POST",
data: jsonString,
dataType: "text",
success: function(){
alert(\"success\");
},
error:function(){
alert(\"failure\");
}
});
};
</script>
Servlet:
public class UpdateSetvil extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
List<SetvilJsonAttributes> setvilAttrs = new LinkedList<SetvilJsonAttributes>();
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
out.println("Inside servlet");
// 1. get received JSON data from request
BufferedReader br = new BufferedReader(new InputStreamReader(request.getInputStream()));
String json = "";
if(br != null){
json = br.readLine();
}
System.out.println(json.toString()); // [{"id":"","notes":""},{"id":"18001","notes":"fdafd"},{"id":"8350","notes":"daggda"},{"id":"8056","notes":"gfdagdfa"}]
// 2. initiate jackson mapper
ObjectMapper mapper = new ObjectMapper();
// 3. Convert received JSON to Class
SetvilJsonAttributes setvilatt = mapper.readValue(json, SetvilJsonAttributes.class);
// 4. Set response type to JSON
response.setContentType("application/json");
setvilAttrs.add(setvilatt);
for (int i=0;i< setvilatt.size(); i++) {
System.out.println(setvilatt.get(i).getId());
}
}
private class SetvilJsonAttributes {
Integer id;
String notes;
String eta;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getNotes() {
return notes;
}
public void setNotes(String notes) {
this.notes = notes;
}
public String getEta() {
return eta;
}
public void setEta(String eta) {
this.eta = eta;
}
}
}
Error: java.io.IOException: Error parsing JSON request string
I kindly request anyone to help me on this.I have been stuck and unable to proceed further.

try this,
$.ajax({
url: "/updatesetvil",
type: "POST",
// The key needs to match your method's input parameter (case-sensitive).
data: { jsonString: jsonString},
contentType: "application/json; charset=utf-8"
dataType: "text",
success: function(data){
alert(\"success\"+data);
},
error:function(){
alert(\"failure\"+data);
}
});

Suggestion
If you are getting issues while parsing a JSON string then I can help you to parse the JSON string into Java object using GSON library as illustrated in below sample code.
Please note id should be String otherwise it will result into NumberFormatException for empty id values.
Sample code:
class SetvilJsonAttributes {
private String id;
private String notes;
// getter & setter
}
String jsonString="[{\"id\":\"\",\"notes\":\"\"},{\"id\":\"18001\",\"notes\":\"fdafd\"},{\"id\":\"8350\",\"notes\":\"daggda\"},{\"id\":\"8056\",\"notes\":\"gfdagdfa\"}]";
Type type = new TypeToken<ArrayList<SetvilJsonAttributes>>() {}.getType();
ArrayList<SetvilJsonAttributes> data = new Gson().fromJson(jsonString,type);
System.out.println(new GsonBuilder().setPrettyPrinting().create().toJson(data));
output:
[
{
"id": "",
"notes": ""
},
{
"id": "18001",
"notes": "fdafd"
},
{
"id": "8350",
"notes": "daggda"
},
{
"id": "8056",
"notes": "gfdagdfa"
}
]
If you don't want to change the type of id field then you can try with JsonDeserializer to deserializer it as per your need.
Please have a look at my another posts here and here for JsonDeserializer.

See these three lines:
System.out.println(json.toString()); // [{"id":"","notes":""},{"id":"18001","notes":"fdafd"},{"id":"8350","notes":"daggda"},{"id":"8056","notes":"gfdagdfa"}]
ObjectMapper mapper = new ObjectMapper();
SetvilJsonAttributes setvilatt = mapper.readValue(json, SetvilJsonAttributes.class);
The value of json is a JSON array. But, then you map it to SetvilJsonAttributes, which does not support JSON array. You can convert this json to a List of SetvilJsonAttributes using:
ObjectMapper mapper = new ObjectMapper();
ArrayList<SetvilJsonAttributes> setvilatt = mapper.readValue(json, new TypeReference<ArrayList<SetvilJsonAttributes>>(){});

I have used JSONArray and it worked out
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
out.println("Inside servlet");
Connection connector = MysqlConnector.getDBCon();
StringBuffer sb = new StringBuffer();
String line = null;
try {
BufferedReader reader = request.getReader();
while ((line = reader.readLine()) != null) {
sb.append(line);
}
json = sb.toString();
} catch (Exception e) {
System.out.println("Exception while reading JSON String");
e.printStackTrace();
}
System.out.println("String is " + json);
try {
JSONArray inputArray = new JSONArray(json);
for (int i=0; i < inputArray.length(); i++) {
JSONObject c = inputArray.getJSONObject(i);
String id = c.getString("id");
String notes = c.getString("notes");
System.out.println(id + "--> " + notes);
} catch (JSONException e) {
// crash and burn
System.out.println("Parse exeception for array");
e.printStackTrace();
}
}
