In a system all data is exposed via URL due to the sending method GET. I need to send via POST.

Code:

<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    <form action="adicionarContato" enctype="multipart/form-data">
        <br><label>Nome:</label>
        <input type="text" name="nome">

        <br><label>email</label>    
        <input type="text" name="email">

        <br><label>Endereco</label>
        <input type="text" name="endereco">

        <br><label>Data Nascimento</label>
        <input type="text" name="dataNascimento">

        <br><input type="submit" value="gravar">

    </form>
</body>
</html>

Change your form tag to this:

<form action="adicionarContato" enctype="multipart/form-data" method="POST">
    <br><label>Nome:</label>
    <input type="text" name="nome">

    <br><label>email</label>    
    <input type="text" name="email">

    <br><label>Endereco</label>
    <input type="text" name="endereco">

    <br><label>Data Nascimento</label>
    <input type="text" name="dataNascimento">

    <br><input type="submit" value="gravar">

</form>
