I'm new using these tools so you'll probably find this very stupid.
I'm getting this error, when trying to access my webapp (where I'm supposed to show every user in my database "User" table.
HTTP ERROR 500

I don't know if it's necessary to keep going with the DAOs ... the problem is that the error names a "Contact" and I don't even use that name in anything at all (I use "Usuario"). And yes, before you ask, I did replace some internet code which did have the word "contact" but I replaced them all to my code. So maybe this caused a mess but I'm really lost now. Hope you can help me. If there's something you don't understand don't hesitate to ask.
Thank you a lot!
You are only putting your object into a map. You need to put your objects in http request. Spring has model objects Model and ModelAndView that do this as shown below:-
<code>
#RequestMapping("/index")
public String listUsers(Model model) {
model.addAttribute("usuario", new Usuario());
model.addAttribute("usuarioList", usuarioService.listUsuario());
return "usuario";
}
</code>
OR
<code>
#RequestMapping("/index")
public ModelAndView listUsers() {
ModelAndView mav = new ModelAndView("usuario");
mav.addObject("usuario", new Usuario());
mav.addObject("usuarioList", usuarioService.listUsuario());
return mav;
}
</code>
What I can suggest you here is delete the target folder where the build is prepared and recreate the build and war and then run, if problem persists then let us know with the necessary files. Thanks

Thank you for your attention.
Good deeds.
Based on the assumption that you've filled in valid data in the form you'r submitting to the post. You will need standard setter (and maybe getter for view) methods for spring to be able to fill your model entity.
Also <tr th:each="matrix : ${matrix}"> is problematic as you'r defining the same variable name twice this way.
To prevent errors like these it's good practice to add bean validation with #NotNull on your y and x variables and modify controller as such
#PostMapping("/generate")
public String matrixRegistration(#Valid Matrix matrix, Model model, BindingResult bindingresult)
{
if (bindingResult.hasErrors())
{
//handle errors
}
matrix.fillArrayList();
model.addAttribute("matrix", matrix);
return "redirect:/";
}
see https://zetcode.com/spring/bindingresult/ for more details
I solved my own problem myself.
<table>
<tr th:each="values :${matrixArray}">
<th:block th:each="val :${values}">
<td th:text="*{val}"></td>
</th:block>
</tr>
</table>
Thans for suggestions. Its help a lot.
I have this uni project going on, and I'm stuck on this error and can't find the solution.
First there's the JSP file that loads a list
<%#page import="Controllers.RestClient"%>
<%#page import="java.util.List"%>
<%#page import="Model.Stationss"%>
<%#page import="javax.xml.bind.JAXBException"%>
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<label for="Origin">Embark Station:</label>
<select name ="StartStation" id="stations">
<%
List<Stationss> listS = RestClient.getStations();
for (int i = 0; i < listS.size(); i++) {
out.print("<option value = " + i + ">" + listS.get(i).getName() + "</option>");
}
%>
</select><br>
</body>
</html>
There's also the ReST client access
package Controllers;
import java.util.List;
import Model.Stationss;
import java.util.ArrayList;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Invocation;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.GenericType;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.xml.bind.JAXBException;
public class RestClient {
public static List<Stationss> getStations() {
System.out.print("test");
String link = "http://localhost:8080";
String path = "/Service/webresources/pkg.service.stations";
Client client = ClientBuilder.newBuilder().build();
WebTarget target = client.target(link).path(path);
Invocation.Builder invocation = target.request(MediaType.APPLICATION_XML);
System.out.print(link);
System.out.print(path);
Response response = invocation.get(Response.class);
System.out.print(response);
List<Stationss> list = response.readEntity(new GenericType<List<Stationss>>() {
});
System.out.print(list);
return list;
}
};
and after I have the model
/*
* Click nbfs://nbhost/SystemFileSystem/Templates/Licenses/license-default.txt to change this license
* Click nbfs://nbhost/SystemFileSystem/Templates/Classes/Class.java to edit this template
*/
package Model;
import javax.persistence.Transient;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement
public class Stationss {
private int id;

private int zone;
Gate gates = new Gate(zone);
public int getId() {

}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getZone() {
return zone;
}
public void setZone(int zone) {
this.zone = zone;
}
public Gate getGates() {
return gates;
}
public void setGates(Gate gates) {
this.gates = gates;
}
public Stationss() {
}
public Stationss(int id, String name, int zone) {
this.id = id;
this.name = name;
this.zone = zone;
}
#Transient
public CheckTicket enter(String xml) {
return gates.enter(xml);
}
#Transient
public boolean exit(String xml) {
return gates.exit(xml);
}
}
and at last, the huge error screen

It's my first time learning java and I'm completely at loss on what I'm doing wrong.
I know the link the xml list is working fine.
You have missing dependencies on your classpath
See the stack trace
javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath.
This answer might be helpful
This is how far i have come trying to respond with a List<> of Users to a Client . Every time i get Error 500 so i tried to respond with just a String and it worked so there is not a problem with the server/client communication. I searched the Internet and i found some examples that they returned Lists<> without error but i can't get mine to work.

I can't post this as a comment so here it is. You can't really expect HttpUrlConnection.getContent to return a List of User instances. From the Javadoc
This method first determines the content type of the object by calling
the getContentType method. If this is the first time that the
application has seen that specific content type, a content handler for
that content type is created:
If the application has set up a content handler factory instance using
the setContentHandlerFactory method, the createContentHandler method
of that instance is called with the content type as an argument; the
result is a content handler for that content type. If no content
handler factory has yet been set up, or if the factory's
createContentHandler method returns null, then the application loads
the class named:
The usual way to get the content (when using HttpUrlConnection) is by using BufferedReader in combination with InputStreamReader something like
if(resCode==200){
reader = new BufferedReader(new InputStreamReader(conn.getInputStream(),"UTF-8"));
stringBuilder = new StringBuilder();
String line=null;
while((line = reader.readLine()) != null){
stringBuilder.append(line + "\n");
}
}
But even now you will only get your User list as one large string (formatted as XML) and you should use an object mapper to convert the content/entity string to a List of User instances.
If, on the other hand, you used a Jersey client, it would be able to do the conversion automatically for you (it uses JAXB under the hood). Your Jersey client code might look something like (not tested)
WebTarget target = client.target(UriBuilder.fromUri("http://localhost:11118/EclassServer/webresources/UserService/users").build());
GenericType<List<User>> genType = new GenericType<List<User>>();
List<User> userList =(String) target.request().accept(MediaType.XML_APPLICATION).get(genType);
You don't have a correct root element. You've added the #XmlRootElement annotation to the User class, but it's not the root element as you're returning a list of users not a single user.
I recommend to specify a XSD and generate the JAXB classes rather than writing them yourself.

Your configuration is wrong
<servlet-class>org.springframework.web.servlet.DispatcherServlet.class</servlet-class>
The <servlet-class> element expects the name of a class. There is no such class called
org.springframework.web.servlet.DispatcherServlet.class
You probably meant
org.springframework.web.servlet.DispatcherServlet
I'm following this guide:
http://code.google.com/intl/it-IT/apis/documents/docs/2.0/developers_guide_java.html
I just need to retrieve a token and use it to get a list of documents, so i used AuthSub to get a single use token, and this seems to work: i get a string like this
1/BM14a4NnfKf........
Now i'm trying to do this: http://code.google.com/intl/it-IT/apis/documents/docs/2.0/developers_guide_java.html#Versioning
1) Specifying a version
2) Retrieving a list of documents
I'm managing these functions in a class called TokenServiceImpl:
package mui.server.services;

import java.net.MalformedURLException;
import java.net.URL;

import com.google.gdata.util.AuthenticationException;
import com.google.gdata.util.ServiceException;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
public class TokenServiceImpl extends RemoteServiceServlet implements
TokenService {
private static final long serialVersionUID = 1L;
String nextUrl = "";
String scope = "https://docs.google.com/feeds/";
boolean secure = false; // set secure=true to request secure AuthSub tokens
boolean session = true;
String authSubUrl = "";
#Override
public String getToken(String requestUri) {
nextUrl = requestUri;
authSubUrl = AuthSubUtil.getRequestUrl(nextUrl, scope, secure, session);
return ", clicca <a href='" + authSubUrl
+ "'>qui</a> per regalarmi un token! (esempio Google Docs)";
}
#Override
public String getDocsInfo(String token) {
String elenco=", grazie del token, eccolo qui:<br> " + token + "<br>";
DocsService client = new DocsService("yourCo-yourAppName-v1");
client.setProtocolVersion(DocsService.Versions.V2);
try {
URL feedUri = new URL(
"https://docs.google.com/feeds/documents/private/full/");
DocumentListFeed feed = client.getFeed(feedUri, DocumentListFeed.class);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ServiceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return elenco;
}
}
But in the method getDocsInfo (which get the string "token", the token previously retrieved) the only row
DocumentListFeed feed = client.getFeed(feedUri, DocumentListFeed.class);
gives me errors:

What am I missing? I'm really confused... I'm at the beginning with all this, maybe it's something stupid... but is't it just what's exactly written in the guide?
And here in this example
http://code.google.com/intl/it-IT/apis/documents/docs/2.0/developers_guide_java.html#ListDocs
where do I need to use the token i retrieved?
Two steps more were required:
1) change the token to "sessionToken":
String sessionToken = AuthSubUtil.exchangeForSessionToken(token, null);
2) associate the token to the client:
DocsService client = new DocsService("yourCo-yourAppName-v1");
client.setAuthSubToken(sessionToken);
