Lucas. D's questions

I have a fairly simple API that, when hitting one of the endpoints, gives me the following stack trace

Microsoft.AspNetCore.Routing.Matching.AmbiguousMatchException: The request matched multiple endpoints. Matches:

VimTube.Controllers.CategoryController.GetAllCategories (VimTube) VimTube.Controllers.CategoryController.GetCategoryByName (VimTube)

I understand that it is failing because I have two methods that point to the same URL. The same are the following

[HttpGet]
public Task<ActionResult<IEnumerable<Category>>> GetAllCategories()
{
    return _repository.FindAll();
}

[HttpGet]
public IEnumerable<Category> GetCategoryByName([FromQuery]string name)
{
    return _repository.ListCategoriesWhichStartsWith(name);
}

And my controller class is prefixed with vimtube/categories .

My idea would be to have these url's

1. vimtube/categories returns a list of all categories.
2. vimtube/categories?name=Ent returns the categories that start with the query you passed to it.

I read that with [FromQuery] this was possible, but apparently it is not. Thank you!

I have a .JAR file which contains my Spring application with all its dependencies. I also hired a VPS which today the support tells me that their VPS are " unmanaged ", that is, not managed (I don't know if this makes what I want to do impossible).

The DocumentRootwhich is in the directory /etc/apache2/sites-enabled/points to /var/www/html. Here is a file with the extension .html which is the default file that the browser loads when making a request to the domain that points to my server.

Without having much knowledge of the subject, I have uploaded my .JAR file to that directory and from the command line with java -jar file_name.jar I execute my application. It gets up and starts without problems, but when I enter my domain again I get the typical page with the title

" Index of / " and the list of files in that folder.

I have everything installed on the server, mysql, maven, java, etc.

Does my application go in another directory or does this type of application run on unmanaged servers ?

I am trying to send an email from my web app but I have a very strange error.

org.springframework.mail.MailSendException: Failed messages: javax.mail.MessagingException: IOException while sending message;
nested exception is: java.io.IOException: No MimeMessage content

This is my Mail class

public class Mail {

    private String from;
    private String subject;
    private String replyTo;
    private String text;
    private String to;

    public String getFrom() {
        return from;
    }

    public void setFrom(String from) {
        this.from = from;
    }

    public String getSubject() {
        return subject;
    }

    public void setSubject(String subject) {
        this.subject = subject;
    }

    public String getReplyTo() {
        return replyTo;
    }

    public void setReplyTo(String replyTo) {
        this.replyTo = replyTo;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {

    public String getTo() {
        return to;
    }

    public void setTo(String to) {
        this.to = to;
    }

    public Mail(String from, String subject, String replyTo, String text) {
        this.from = from;
        this.subject = subject;

            mail.setSubject(mail.getSubject());
            mail.setReplyTo(mail.getReplyTo());
            mail.setText(mail.getText());

            LOG.error("ERROR SENDING EMAIL", e);
            return "redirect:/contact";

}

Debugging the code I have realized that this line

mail.setText(mail.getText()); 

null always comes, something very rare since I write a message in the Textearea. All the other fields arrive perfectly and if I forcefully pass a String to my setText method, the mail arrives correctly with that String, but obviously I want the user to send an email with the message they want.

Best regards.

I'm using TINYMCE so that in a form with a textarea the user can give some styles to the text. This way in my database this field is saved, for example, as follows.

<p><strong>Some description goes here...</strong></p> 

The issue is that when displaying it on a page it looks like this, and what I need is that the labels are not seen and the formatted/rendered text is seen like here

Some description goes here...

I've tried the <pre>and tags <code>but they don't give me the results I need.

I am using Thymeleaf with Spring framework. In the IDE I am trying to show the description in the following way

<article th:text="${product.description}"></article>

Thanks since now.

I have the following HTML code which consists of two Radio Buttons. I need that if the user chooses one, depending on which it is, the "Discount Percentage" field is active or not.

<div class="form-group">
    <label for="isProductDiscounted" class="text-uppercase font-weight-bold">Is Product Discounted?</label>
    <div class="btn-group w-100" data-toggle="buttons" name="isProductDiscounted">
        <label class="btn btn btn-blue-grey waves-effect w-50 form-check-label active">
            <input id="isDiscounted" class="form-check-input" name="isDiscounted" type="radio" value= 0 th:field="*{discounted}" autocomplete="off" checked> No discounted
        </label>

        <label class="btn btn btn-blue-grey waves-effect form-check-label w-50">
            <input id="isNotDiscounted" class="form-check-input" name="isDiscounted" type="radio" value= 1 th:field="*{discounted}"> Discounted
        </label>
    </div>
</div>

<div class="form-group">
    <label for="discountPercentage" class="text-uppercase font-weight-bold">Discount Percentage</label>
    <input type="number" class="form-control" id="discountPercentage" th:field="*{discountPercentage}">
    <small class="form-text text-danger" th:if="${#fields.hasErrors('discountPercentage')}" th:errors="*{discountPercentage}"></small>
</div>

By default, when loading the page the selected radio button is "No discounted". I have tried the following code, but it doesn't work at all, since the input is always disabled regardless of the selected radio button.

var discounted = document.getElementById('isDiscounted');
var no_discounted = document.getElementById('isNotDiscounted')
var discount_percentage = document.getElementById('discountPercentage')

if(discounted.checked) {
    discount_percentage.disabled = true;
} else  {
    discount_percentage.disabled = false;
}

Thanks in advance.

I have the following code in my controller which is responsible for loading a client with a photo.

@RequestMapping(method = RequestMethod.POST, value = "/form")
public String guardar(@Valid @ModelAttribute("cliente") ClienteEntity cliente, BindingResult result, @RequestParam("file") MultipartFile foto, RedirectAttributes flash, SessionStatus sesion) { 


if (result.hasErrors() || foto.getSize() > 5242880L) {
            LOG.info("La foto pesa " + foto.getSize());
            return "form";
        } else {
             //...
        }

}

In my application.properties I have the following

spring.http.multipart.max-file-size=5MB
spring.http.multipart.max-request-size=5MB

So that images with a weight greater than 5MB cannot be uploaded, but when I do, I get the same exception twice, which is the following

org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (10506931) exceeds the configured maximum (5242880)

I've tried using a try-catch and even validation with the if but my program doesn't get to enter the controller and I can't take any action to prevent the exception from being thrown.

EDIT

On this page I found the following code, I no longer get the exception but it does not redirect me to my error view either

@ControllerAdvice
public class GenericExceptionHandler {

    @ExceptionHandler(value = MultipartException.class)
    public ModelAndView handleFileUploadException(MultipartException mpex, HttpServletRequest request) {

        ModelAndView modelAndVew = new ModelAndView("error");
        modelAndVew.addObject("errorMsg", mpex.getMessage());
        return modelAndVew;
    }

In the console I get the size warnings

2018-03-01 11:45:08.157 WARN 13880 --- [nio-8080-exec-4] .mmaExceptionHandlerExceptionResolver : Resolved exception caused by Handler execution: org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request ; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (10506931) exceeds the configured maximum (5242880) 2018-03-01 11:45 :09.148 WARN 13880 --- [nio-8080-exec-7] .mmaExceptionHandlerExceptionResolver : Resolved exception caused by Handler execution: org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.

And Chrome throws me an ERR_CONNECTION_RESET

Edit2

Add Apache Tomcat as a server since I didn't have any selected.

In the multipart-config I have the following

<multipart-config>
      <!-- 50MB max -->
      <max-file-size>52428800</max-file-size>
      <max-request-size>52428800</max-request-size>
      <file-size-threshold>0</file-size-threshold>
</multipart-config>

And in controller again add this

if(foto.getSize() >= 5242880L) {
            LOG.error("---------------------- LA FOTO PESA DEMASIADO ----------------------");
            return LISTAR;
        }

But it still doesn't enter my if, so it doesn't do the address and I get Chrome's ERR_CONNECTION_RESET

I have a repository class that implements from another a method to get all my clients

@Repository
public class ClienteRepositoryImpl implements ClienteRepository{

    private EntityManager em;

    @Override
    @Transactional(readOnly = true)
    public List<ClienteEntity> findAll() {

        return em.createQuery("from Cliente").getResultList();

    }

}

The problem is that in the return line it throws me the following warning

Type safety: The expression of type List needs unchecked conversion to conform to List

I have searched in different places and it is not so clear to me why Java throws this at me. I have also read some questions on the subject in English, such as this one where the use of the @SuppressWarnings("unchecked") tag is even recommended, as well as disabling the warnings that cannot be avoided, something that for me is a bad practice .

How could I avoid this type of warning without the use of tags like the one mentioned?

I have the following code which shows some products in a combobox

    <body>
        <%

        List<String> productos = new ArrayList<>();
        productos.add("TV");
        productos.add("PC");
        productos.add("Stereo");
        productos.add("Iphone");

        %>

        <select>
            <%
                for (String p : productos)
                {
                    out.println("<option>" + p + "</option>");
                }

            %>
        </select>
    </body>
</html>

But when I run it I get the following error

I have the following code with which I am testing how to encrypt passwords with SHA1. I have used adapted code from two different sources but both bring me different results.

import java.io.UnsupportedEncodingException;
import java.math.BigInteger;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import javax.xml.bind.DatatypeConverter;

public class Encriptacion 
{

    public static void main(String[] args) throws UnsupportedEncodingException {

        String password = "Lucas";

        try 
        {
            //da39a3ee5e6b4b0d3255bfef95601890afd80709
            MessageDigest md = MessageDigest.getInstance("SHA1");
            md.update(password.getBytes(), 0 , password.length());
            System.out.println(new BigInteger(1, md.digest()).toString(16));

            //CBEDE02E8C227684972AB1467409D98C0D0D5A5D
            MessageDigest msdDigest = MessageDigest.getInstance("SHA1");
            msdDigest.update(password.getBytes("UTF-8"), 0, password.length());
            password = DatatypeConverter.printHexBinary(msdDigest.digest());
            System.out.println(password);

        } 
        catch (NoSuchAlgorithmException ex) 
        {
            System.out.println("ERROR : ");
            ex.printStackTrace(System.out);
        }

    }

}

I do not know what is the reason why it brings me different results or what is the correct way to encrypt a password.

I am doing a program of Librosand Autoreswhere one autorhas many libros.

When inserting a new one, LibroI need to obtain the iddel autorto save it as fk_dniin the table Libros, so I have the following code which loads me comboboxwith those Autoresthat are saved in my database.

public void insertarLibro()
    {
        String url = "jdbc:sqlserver://localhost:1433;databaseName=Biblioteca";
        String user = "mi_usuario";
        String password = "mi_contraseña";
        String fk_dni = "SELECT dni FROM Autores WHERE nombre = '?'";


        try
        {
            Connection cn = DriverManager.getConnection(url, user, password);
            PreparedStatement ps = cn.prepareStatement(fk_dni);
            ResultSet rs = ps.executeQuery();
            String nombre = (String)cboAutor.getSelectedItem();

            while(rs.next())
            {
                ps.setString(1, nombre);
            }

            System.out.println("DNI : " + rs.getString(1));
        }
        catch(SQLException e)
        {
            System.out.println("ERROR : ");
            e.printStackTrace(System.out);
        }

    }

But my program returns the following error

com.microsoft.sqlserver.jdbc.SQLServerException: Result set has no current row

So I deduce that my program is not entering my loop while. In case I remove the single quotes in my query fk_dni, the error it throws me is:

The value is not set for parameter number 1.

The System.out.println("DNI : " + rs.getString(1));is temporary since I only use it to verify that the data is displayed correctly.

Hello, I have my class Gestorwith the following code:

Class gestor

        private final String cadena = "jdbc:sqlserver://localhost:1433;databaseName=Persona";
        public final String usuario = "mi_usuario";
        public final String contrasenia = "mi_contraseña";


        ArrayList<Persona> cargarPersonas()
        {
            ArrayList<Persona> personas = new ArrayList<>();

            try

                    String nombre = rs.getString("nombre");
                    String apellido = rs.getString("apellido");
                    int edad = rs.getInt("edad");

                    Persona p = new Persona(nombre,apellido,edad);
                    personas.add(p);
                }

                rs.close();
                st.close();
                cn.close();

            }catch (SQLException e)
            {
                System.out.println("ERROR : " + e);
            }

            return personas;
        }

}

I have a JFramecall ListadoPersonaswith a JListcall lstPersonas. I would like to be able to load it with the data from the ArrayList.

Hello, I have the following code

public class main {


    private static Connection cn;

    public static Connection getConexion() {
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            cn = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=Persona");

        } catch (ClassNotFoundException | SQLException e) {
            cn = null;
        }

        return cn;
    }


    public static void main(String[] args) {
        //menuPrincipal mp = new menuPrincipal();
        //mp.setVisible(true);

        Connection prueba = main.getConexion();

        if (prueba != null) {
            System.out.println("Conexion realizada con exito...");
        } else {
            System.out.println("Error en la conexion...");
        }
    }
}

Which returns me "Error in the connection". I have managed to do the same through the "Services" panel as you can see below

But my method doesn't return what I'm looking for.

I have the following code that generates a table in php returning me the data stored in a database in mysql

require("conexion.php");

$consulta = mysqli_query($conexion, "SELECT * FROM clientes");

if (!$consulta) {
    die("Fallo al realizar la consulta");
}

echo ("<table border='1px'>");
echo ("<th> NOMBRE </th> <th> MEDIO DE PAGO </th> <th>PLAN CONTRATADO</th> <th> MODIFICAR </th> <th> ELIMINAR </th>");
while ($clientes = mysqli_fetch_array($consulta)) {
    echo ("<tr>");
    echo ("<td>$clientes[nombre]</td>");
    echo ("<td>$clientes[medioPago]</td>");
    echo ("<td>$clientes[plan]</td>");
    echo ("<td><a href='modificar.php?idC=$clientes[id]'>Modificar </a></td>");
    echo ("<td><a href='eliminar.php'>Eliminar </a></td>");
    echo ("</tr>");
}
echo ("</table>");

As you can see, each record also generates a link that takes me to the modify.php page to modify the data if necessary. With idC=$clients[id] I get the ID of the client that I want to modify. In my modify.php file I have the following code

<form action="modificar.php">
        <label>Nuevo nombre: </label>
        <input type="text" name="nuevoNombre" placeholder="Ingrese el  nuevo nombre">

        <label>Medio de pago: </label>
        <select name="nuevoMedioPago">
            <option value="tarjeta">Tarjeta de credito</option>
            <option value="rapipago">Rapipago - Pagofacil</option>

Which throws me an error on the line where I have my sql query to update the data. In case I use GET or POST both in the form and when obtaining the new name, etc., the error it throws me is Undefined index .

Greetings and thanks.

I have 3 images, each of them within a link

<a href="contratar.php?plan=basico" value="basico"><img src="images/p1.gif"></a>
<a href="contratar.php?plan=avanzado" value="avanzado"><img src="images/p2.gif"></a>
<a href="contratar.php?plan=profesional" value="profesional"><img src="images/p3.gif"></a>

Clicking on any of them takes me to my contract.php page and here I need to show the plan that the user selected.

Thanks in advance.

Hello, I am trying to connect Netbeans with a database but I have the following error

Cannot establish a connection to jdbc:sqlserver://CRONOPIO:1433;databaseName=ppm using com.microsoft.sqlserver.jdbc.SQLServerDriver (Could not make TCP/IP connection to host CRONOPIO, port 1433. Error: "Connection refused : connect Check the connection properties, verify that there is an instance of SQL Server running on the host and accepting TCP/IP connections on the port, and verify that there are no firewalls blocking TCP connections on the port.".)

My SQL Server has no instance, but the database exists and my port is enabled:

The only thing that occurs to me, since I tried several things, is that perhaps not having an instance name, the empty field is what generates the error. Greetings.

I am having trouble connecting with "SQL Sever Authentication".

When I installed the program in the Database Engine Configuration part I selected mixed authentication mode, this created an administrator "CRONOPIO\Lucas(Lucas)" but when trying to log in from SQL I get the error:

Cannot connect to CRONOPIO. Login failed for user 'Cronopio\Lucas' . (Microsoft SQL Server Error: 18456.

I've also tried logging in using just "Lucas" but I still get the error. There are no problems logging in with Windows authentication but I need to do some work and it is necessary to log in with SQL.

Update:

I'm wanting to make a Rock, Paper, Scissors game in Python, nothing complicated. The player starts with 2 points and depending on whether he wins or loses, value is added or subtracted. The problem is that it is not saved in the variable that I declare first, so that even if it reaches 0 points, the while continues to execute.

from random import randint

pi = "Piedra"
pa = "Papel"
ti = "Tijera"

puntos = 2

while puntos > 0:


    elemento = input("¿Piedra, papel o tijera? : ")
    maquina = randint(0,2)


    def piedra(puntos):
        if elemento.lower() == "piedra" and maquina == 0:
            print ("Empate, la maquina eligio ", pi , " ! ")
        elif elemento.lower() == "piedra" and maquina == 1:
            print ("Perdiste, la maquina eligio ", pa, " ! ")
            puntos -= 2
            print ("Tienes " , puntos , " puntos.")
        elif elemento.lower() == "piedra" and maquina == 2:
            print ("Ganaste, la maquina eligio ", ti, " ! ")
            puntos += 2
            print ("Tienes " , puntos , " puntos.")

    def papel(puntos):
        if elemento.lower() == "papel" and maquina == 0:
            print ("Ganaste, la maquina eligio ", pi, " ! ")
            print ("Tienes " , puntos , " puntos.")
            puntos += 2
        elif elemento.lower() == "papel" and maquina == 1:
            print ("Empate, la maquina eligio ", pa, " ! ")
        elif elemento.lower() == "papel" and maquina == 2:
            print ("Perdiste, , la maquina eligio " , ti, " ! ")
            puntos -= 2
            print ("Tienes " , puntos , " puntos.")

    def tijera(puntos):
        if elemento.lower() == "tijera" and maquina == 0:
            print ("Perdiste, la maquina eligio " , pi, " ! ")
            puntos -= 2
            print ("Tienes " , puntos , " puntos.")
        elif elemento.lower() == "tijera" and maquina == 1:
            print ("Ganaste, la maquina eligio " , pa, " ! ")
            print ("Tienes " , puntos , " puntos.")
            puntos += 2
        elif elemento.lower() == "tijera" and maquina == 2:
            print ("Empate, la maquina eligio " , ti, " ! ")

    piedra(puntos)
    papel(puntos)
    tijera(puntos)

I have in my "Upload" view the following code:

<form action="" method="post" enctype="multipart/form-data">

<label for="file">Filename:</label>
<input type="file" name="file" id="file" />

<input type="submit" />
</form>

And in my controller "SubidaController" the following

public ActionResult Subida()
    {
        return View();
    }

I need that from the form of my view I can load an image and then go to the index and see it there. That is to say that when uploading an image it must be saved within a physical directory of my project so when restarting or reloading the page the images are not lost. I have searched and tried the methods using sites like this http://haacked.com/archive/2010/07/16/uploading-files-with-aspnetmvc.aspx/ but have not achieved what I need.

Here I found the way to do it, the only problem I have is that they are not shown on my Home page, they are only saved in the "images" folder of my project http://www.dotnetdreamer.net/upload-imagedisplay-image -in-aspnet-mvc

Upload View

UploadController

HomeController

I am working with an API and I have the following code in php

<?php
$link = file_get_contents('http://api.steampowered.com/IEconItems_440/GetPlayerItems/v0001/?key=APIKEY&SteamID=STEAMID64&format=json');

$myarray = json_decode($link, true);

$count = 0;

foreach($myarray['result']['items'] as $item)
{
    if($item['defindex'] == 5021)
    { 
            $count++;
    }
}
echo $count;
?>

What this will do is throw me a numeric value that I want to display in a table cell. Unlike other php files that can be executed when a button is clicked, I need the result that my php returns to be displayed as soon as the page loads.

Good afternoon people!. I have searched for half an hour and I have not found anything that works for me or gives me positive results. I have a pivot table that changes the number of rows to display based on what one selects from the DropDownList. The problem is that for those cases in which the table has few rows, the footer gets out of place and, as you can see below, it is not "stuck" properly to the footer.

I have tried with the position attribute, with others of which I had never heard but I can't get the footer to always stick to the footer. At the moment this is what I have in my css;

footer
{
    margin-top:50px;
    width:100%;
    height:200px;
    background-color:red;
}

From already thank you very much!
