httpclient athentification issue

Hi guys, I have an issue to login to a website with a simple form login.

My code always returns website login page despite the fact that all the parameters are correct and I'm trying to access to a home page. I'm using the classic AuthScope.ANY method.
thanks for your help.

client.getState().setCredentials(

GetMethod method = new GetMethod(url);
method.setDoAuthentication(true);


method.getParams().setParameter(HttpMethodParams.R ETRY_HANDLER,
new DefaultHttpMethodRetryHandler(3, false));

try {

int statusCode = client.executeMethod(method);

if (statusCode != HttpStatus.SC_OK) {
System.err.println("Method failed: " + method.getStatusLine());
}

//ConnectIntellio2 connec = new ConnectIntellio2();

InputStream responseBody = method.getResponseBodyAsStream();
File f=new File("outFile.html");

BufferedOutputStream out=new BufferedOutputStream( new FileOutputStream(
f.getName() ) );

byte buf[]=new byte[1024];
int len;
while((len=responseBody.read(buf))>0)
out.write(buf,0,len);
out.close();
responseBody.close();

System.out.println("Fichier créé");


} catch (Exception e) {
System.err.println("Fatal protocol violation: " + e.getMessage());
e.printStackTrace();

} finally {

method.releaseConnection();
}
}
