  <html>
 <head>
 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
 </head>
 <body>

<html:file properties="tonFichier" name="tonForm"/>

 public void executeTest() {

  java.util.Date d = new java.util.Date();
  System.out.println(d.toString()); } 

 %>

 <form enctype="multipart/form-data" method="get">

    You can do as follows.

    if(request.getParameter("btnSubmit")!=null) //btnSubmit is the name of your button, not id of that button.
{
    java.util.Date d = new java.util.Date();
    System.out.println(d.toString()); 
}

<input type="submit" id="btnSubmit" name="btnSubmit" value="Execute Test"/>

    onclick="executeTest()" with your button tries to invoke a Javascript function. Change your button tag as mentioned in the above code and encolse this code within a sciptlet. It will do the job when you click this button.

    Additionally, you may want to replace

    System.out.println(d.toString());

    with

    out.println(d.toString());

    in your code.

    Also, in your form tag, 

    <form enctype="multipart/form-data" method="get">

    the attribute enctype="multipart/form-data" is required when you’re uploading files. You should remove it, if such is not a case and 

    method="post"

    The form attribute enctype="multipart/form-data" can not work, if you use method="get"
