Grazie !
credo di aver risolto proprio con l' iframe.
Codice dell'iframe
codice:
<html>
<head>
<script language="JavaScript" type="text/javascript" src="../js/private/ajax.js"></script>
<script language="JavaScript" type="text/javascript" src="../js/private/jsclasses.js"></script>
</head>
<body>
<FORM METHOD="POST" id="caricaa" name="caricaa" ENCTYPE="multipart/form-data" ACTION="../UploadFile" >
<INPUT NAME="nascosto" TYPE="hidden" >
<label>Name:</label>
<INPUT NAME="documentationNameInput" TYPE="text">
<label>File:</label>
<INPUT NAME="documentationFileInput" TYPE="file" >
<INPUT TYPE="submit" VALUE="Send File" onclick="addDocumentation();">
</FORM>
</body>
</html>
Codice servlet
come si evince basta fare l'output con il codice dell'iframe, dalla servlet
codice:
