PUT /ProductoServlet — Update an Existing Product by ID

Sending a PUT request to the ProductoServlet endpoint updates all fields of an existing product identified by its id. All parameters are passed as query-string values rather than a request body — this is intentional, because Tomcat’s built-in servlet infrastructure does not parse PUT request bodies as form parameters, making query strings the most reliable approach for passing data through doPut().

Request

Method: PUT
URL:

http://localhost:8080/ServidorTiendaPlayeras/ProductoServlet?id={id}&nombre={nombre}&talla={talla}&precio={precio}&stock={stock}

Parameters

integer

required

The primary-key ID of the product to update.

nombre

string

required

The new product name. URL-encode any spaces or special characters (e.g., use %20 or + for spaces).

talla

string

required

The new t-shirt size. Accepted values: CH, M, G, XG.

precio

number

required

The new price in Mexican Pesos (MXN). Parsed server-side as a double.

integer

required

The new inventory count. Parsed server-side as an int.

curl Example

curl -X PUT "http://localhost:8080/ServidorTiendaPlayeras/ProductoServlet?id=1&nombre=Playera%20Oversize&talla=G&precio=350.00&stock=10"

PHP (Laravel) Example

The PlayerasController::update() method builds the query string manually, using urlencode() on nombre to handle special characters:

Http::put(
    $this->apiUrl
        . "?id={$id}"
        . "&nombre=" . urlencode($request->nombre)
        . "&talla={$request->talla}"
        . "&precio={$request->precio}"
        . "&stock={$request->stock}"
);

SQL Executed

UPDATE productos SET nombre = ?, talla = ?, precio = ?, stock = ? WHERE id = ?

Response

success

boolean

true if the UPDATE statement executed successfully; false if the update failed (e.g., no row with the given id exists, or a database error occurred).

Success:

{ "success": true }

Failure:

{ "success": false }

All five parameters — id, nombre, talla, precio, and stock — are required. Omitting id, precio, or stock will cause a NumberFormatException on the server when the servlet attempts to parse the missing value, resulting in {"success": false}.
