[html + java] codifica chiocciolina (@) o altro?

[gaglioppo]

ciao amici,

ho un problema:
ho una form html del tipo:

<FORM METHOD=POST ENCTYPE="multipart/form-data" ACTION="http://............. NAME=........>
E-mail: <INPUT TYPE=TEXT NAME=email >
</form>

in un sito che sto analizzando.
Sto realizzandoun tool java per interrogare la form automaticamente.
il problema è che il sistema mi dice che: Badly formed E-mail Address
mentre se compilo la form a mano tutto funziona.

Sto usando il seguente pezzo di codice

	File prediction =new File("nome");
	File FileProperties = new File(prediction,"MODEL.properties");
	FileWriter outFileProperties = new FileWriter(FileProperties);
	PrintWriter FileP= new PrintWriter(outFileProperties) ;
	FileP.println(http);
	FileP.println(seq);
	FileP.close();
            String fileName = "MODEL.properties";
	Properties props = new Properties();
	FileInputStream in = new FileInputStream(fileName);
             props.load(in);

	URL url = new URL(props.getProperty("URL"));
	props.remove("URL");
	String r = doPost(url, props);

	File outputFile = new File("MODEL.html");
	FileWriter out2 = new FileWriter(outputFile);
	PrintWriter out1= new PrintWriter(out2) ;
	out1.println(r);
	out1.close();

dove:

	public static synchronized String doPost(URL url, Properties nameValuePairs)
	throws IOException
	{
		URLConnection connection = url.openConnection();
		connection.setDoOutput(true);

		PrintWriter out= new PrintWriter(connection.getOutputStream());

		Enumeration enum2 = nameValuePairs.keys();

		while (enum2.hasMoreElements()){
			String name = (String)enum2.nextElement();
			String value = nameValuePairs.getProperty(name);
			char ch;
			if (enum2.hasMoreElements()) ch = '&'; else ch = '\n';
			out.print(name + "="
			+ URLEncoder.encode(value,"UTF-8") + ch);
		}

		out.close();
		BufferedReader in;
		try{
			in = new BufferedReader(new
			InputStreamReader(connection.getInputStream()));
		}
		catch (FileNotFoundException exception){
			InputStream err= ((HttpURLConnection)connection).getErrorStream();
			if (err == null)
				throw exception;
			in = new BufferedReader(new InputStreamReader(err));
		}
		StringBuffer response = new StringBuffer();
		String line;

		while ((line = in.readLine()) != null)
			response.append(line + "\n");

		in.close();
		return response.toString();
	}//fine doPost

e ho creato un file MODEL.properties che contiene:

dove sbagloio?
