I know thatit is not a good practice ,but for sake of testing .

I'm trying to send a value of a parameter to my bank via JSP. I can retrieve the session value (parameter)

The code below works, but he did not write value to database.

anybody help?

Do you know whether the value of fonte is correct and that it exists in column id of a row in table pedido? The statement stmt1.executeUpdate() returns a value. What is that value?

String idOrigem = (String)session.getAttribute( "fonte" );
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/company3", "test3", "password3");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery( "SELECT origem FROM register WHERE origem = " + idOrigem + " ORDER BY id Desc LIMIT 1");;
String fonte = rs.getString("origem"); // <--name field of database
if ( idOrigem != null && !rs.wasNull() ){

// creating Query String
String query = "update pedido set origem = ? where id = ?";

// Creating Statement for query execution
PreparedStatement stmt1 = conn.prepareStatement(query);

stmt1.setString(1, idOrigem);
stmt1.setString(2, fonte);

// Updating Table
