Я получаю сообщение об ошибке при запуске кода, и я понятия не имею, что означает ошибка. Я использую Eclipse с сервером Tomcat версии 8.5. Ошибка говорит о статусе HTTP 500 — внутренняя ошибка сервера. Я пробовал все, но я не мог запустить его вообще. Любая помощь будет высоко оценена.
это код
package test;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
@Path("/hello")
public class Hello {
@GET
@Produces(MediaType.APPLICATION_JSON)
public String sayHelloJSon() {
String resource = null;
return resource;
}
@GET
@Produces(MediaType.TEXT_HTML)
public String sayHelloHTML(@QueryParam("name") String name, @QueryParam("Card_no") String Card_no, @QueryParam("amount") int amount) {
System.out.println("Name is " + name);
System.out.println("Amount is " + amount);
String response;
if(amount > 100000) {
System.out.println("Amount is greater than 1 Lakh");
response = "Credit card not approved";
}else {
System.out.println("Amount is lesser than 1 Lakh");
response = "Approved";
}
return "<html>" + "<title>" + "CC Authorization" + name + "</title>"
+ "<body><h1>" + response + "</h1></body>" + "</html>";
}
}
и это ошибка, которую я получаю
