When submitting the form on the jsp page is running forever

When submitting the form on the jsp page below (cadastroPaciente.jsp), the System is running forever without returning any error.
I've already tested the connection alone in a Test Class and the Servlet without the connection to the database (only building the object and returning it to the screen) worked. But when I put it in the Servlet to save in the database it is running forever and does not save in database.
The buildpath has:
jakarta.servlet.jsp.jstl-api-2.0.0.jar
mysql-connector-java-8.0.26.jar
On the Console there's just this:

I got it! It needed to include the mysql-connector-java-8.0.26.jar in the library (in the lib folder), below the WEB-INF. But thank you for the
DanielBarbarian because he pointed out an important subject about the JOptionPane. Actually my application is not a swing application so the JOptionPane doesn't make sense. This was because I copied it from somewhere else that was probably a Swing application.

Now I want to create them in java project by Retrofit 2.
In my java project I use Retrofit 2 to create http request.
import retrofit2.Response;
import java.util.*;
public class Main {
public static void main(String[] args) {
System.out.println("Start request");
//Map<String, Object> bodyMap = getParams();
List<String> payment_method_types = new ArrayList<String>();
payment_method_types.add("card");
List<String> line_items = new ArrayList<String>();
JsonArray jsonArray = new JsonArray();
JsonObject lineItemsJsonObject = new JsonObject();
lineItemsJsonObject.addProperty("name", "T-shirt");
lineItemsJsonObject.addProperty("description", "Comfortable cotton t-shirt");
lineItemsJsonObject.addProperty("amount", 1500);
lineItemsJsonObject.addProperty("currency", "usd");
lineItemsJsonObject.addProperty("quantity", 1);
jsonArray.add(lineItemsJsonObject);
line_items.add(jsonArray.toString());
TransportService.checkoutSessions("https://example.com/success", "https://example.com/cancel", payment_method_types, line_items, new DefaultRestClientCallback<Void>() {
#Override
public void onSuccess(Response<Void> response) {
//super.onSuccess(response);
System.out.println("checkoutSessions: onSuccess: response = " + response);
}
#Override
public void onError(ErrorResponse errorResponse) {
}
});
}
public static void checkoutSessions(String success_url,
String cancel_url,
List<String> payment_method_types,
List<String> line_items, Callback<Void> callback) {
StripeRestClient stripeMonitorRestClient = RestClientFactory.createRestClient(StripeRestClient.class);
Map<String, String> headerMap = new HashMap<>();
headerMap.put("Accept", "application/json");
headerMap.put("Content-Type", "application/x-www-form-urlencoded");
headerMap.put("Stripe-Version", "2019-03-14");
headerMap.put("checkout_sessions_beta", "v1");
headerMap.put("Authorization", "Bearer sk_test_4eC39HqLyjWDarjtT1zdp7dc");
Call<Void> adMessagesList = stripeMonitorRestClient.checkoutSessions(headerMap, success_url, cancel_url, payment_method_types, line_items);
// asynchronously
adMessagesList.enqueue(callback);
}

spring mvc with angular 2 not working on eclipse, data is not getting loaded

I am tying to test a simple spring mvc with angular 2 project running on eclipse.
The html page is getting displayed, but it is not loading any data from spring backend, any idea why this is happening?

If you want to return anything from a rest controller then you must use #ResponseBody annotation just before function declaration.
Like this in your case:
#RestController
public class CountryController {
#Autowired
private HttpServletRequest request;
CountryService countryService = new CountryService();
#RequestMapping(value = "/countries", method = RequestMethod.GET, headers = "Accept=application/json")
#ResponseBody
public List getCountries() {
List listOfCountries = countryService.getAllCountries();
return listOfCountries;
}
#RequestMapping(value = "/country/{id}", method = RequestMethod.GET, headers = "Accept=application/json")
#ResponseBody
public Country getCountryById(#PathVariable int id) {
return countryService.getCountry(id);
}
.
.
.
}
And in case you are having a rest call which doesn't return anything then make sure to write #ResponseStatus(HttpStatus.NO_CONTENT)
Example:
#RequestMapping(value = "/country/{id}", method = RequestMethod.GET, headers = "Accept=application/json")
#ResponseStatus(HttpStatus.NO_CONTENT)
public void setCountryById(#PathVariable int id) {
countryService.setCountry(id);
}

Look here:
State:<br>
<select>
<option><%
ArrayList<edu.witc.Assignment03.model.States> states = (java.util.ArrayList)request.getAttribute("states");
for (edu.witc.Assignment03.model.States state : states) {
state.getStates();
}%></option>
</select><br>
here request.getAttribute("states"); will be null, cause you have not done request.setAttribute("states", states); in your servlet. that cause the java.lang.NullPointerException..
Possible chances of java.lang.NullPointerException :
if you running directly the jsp page(ctrl+F11). Here states object will not available in request.
if states object is null, then in jsp you have foreach loop to iterate states this will cause exception
you have used two ArrayList to hold onlystates`:
In States class: private List<String> state = new ArrayList<>();
and in CustomerServlet servlet:
private List<edu.witc.Assignment03.model.States> states = new ArrayList<States>();
where one ArrayList is sufficient.
Final solution
change in CustomerServlet class from:
private List<edu.witc.Assignment03.model.States> states = new ArrayList<States>();
to
private edu.witc.Assignment03.model.States states = new States();
then add it to request so that states will available in jsp, in doGet() or anywhere that should adds states to request like:
request.setAttribute("states", states);
and in your jsp render option like:
State:<br>
<select>
<%
edu.witc.Assignment03.model.States states = request.getAttribute("states");
if(states!=null){
for (String state : states.getStates()) {
out.println("<option>"+state+"</option>");
}
}else{
System.out.print("states is null");
}
%>
</select><br>
Note:
Last but not least please avoid script-lets in jsp instead use jstl to render easily

Resin is showing my app as active but I am getting 404

as In topic my war is running without errors on Jetty / Tomcat but when I deploy it to the Resin 4
It shows as running / active in the deployed applications tab on the resin-admin panel. Nothing unusual in the logs as well.
But when I try to access myapp I am getting 404
