How to display a mssg on page before the adf lifecycle process has ended?

Question

Hi;
We have an ADF Application(11.1.1.3). We sign a document with a mobile signature. To do this we use a webservice call. During this call a hash is generated for the user to check and sign the document. Everything is fine but we couldn't find a way to display the generated hash on the page before the adf lifecycle process has finished. The hash should be displayed on the screen while the rest of the method is proceeding. After 2 minutes, the hash is timed out. How can we do this?
The method is as follows:
public boolean docFirstSign(String telNo, int gsmOperator, String evrakNo) {
String filePathToSign = null;
boolean signOpResult = false;
FileProcessor fileP = new FileProcessor();
try {       
filePathToSign = fileP.getFilePathToSign(evrakNo);
byte[] imzalanacakVeri = MobilImza.getBytesFromFile(filePathToSign);
String dataToBeDisplayed = "Size atanmis ve evrak uygulamasi uzerinden goruntulediginiz "+ evrakNo +" numarali evraki mobil olarak imzalayacaksiniz!";
MSS_SenderSoapProxy proxy = new MSS_SenderSoapProxy();
HashResult res = proxy.getHashForGsmOperator(imzalanacakVeri, telNo, 1);
Here the hash is generated. This should be displayed on the page, as at the same time a mobile message is sent to the user to check it and sign it. And the method shoud go on processing.
Logging.getLogger().info("Message -->"+res.getMessage());
//Hash kontrol
if (res.getResultCode()==0) {
SignatureResult sres = proxy.getSignature(dataToBeDisplayed,res.getApTransId()); //Turkce karakter olmayacak
Logging.getLogger().info("sres.getResultCode()-->"+sres.getResultCode());
if (sres.getResultCode()==0) {
byte[] imzaliData = MobilImza.base64Decode(sres.getSignedData());
System.out.println(sres.getMessage());
FileOutputStream fos = new FileOutputStream(new File(filePathToSign));
fos.write(imzaliData);
fos.close();
signOpResult = fileP.docCheckin(evrakNo);
} else {
fileP.cancelCheckout(evrakNo);
} else {
Logging.getLogger().error("Hash Hesaplanamadi");
fileP.cancelCheckout(evrakNo);
return signOpResult;
} catch (Exception e) {
e.printStackTrace();
fileP.cancelCheckout(evrakNo);
return signOpResult;
return signOpResult;
}

Hi,
its a synchronous method execution which means that the display of a popup only works when there is a response to the initial request. What about - as soon as you generated the Hash - show a popup to the user asking him/her to take a note of the hash and then confirm that the document or whatever you want to sign and send to the mobile should be processed. So when the user clicks ok on the message dialog you continue with the remaining of your method
