File Download Example By HTTP URL

[paata]

Hi all.
First of all, I tried to find some example into showcase or forum, but no success.
here is discussion about image file download and upload :
http://<br /> http://forums.smartcl...download<br />
but I think my case a little bit different.

I have http URL for file into my client code like that :
http://someipaddress:port/catalog/catalog/fileName.mp3

how i can download this by clicking (for example) button ?
1.onclick event:

saveFileButton.addClickHandler(new com.smartgwt.client.widgets.events.ClickHandler() {
 @Override
   public void onClick(com.smartgwt.client.widgets.events.ClickEvent event) {
           try {
                  ListGridRecord listGridRecord = sessionsGrid.getSelectedRecord();
                     if (listGridRecord == null) {
                         SC.say("Please Select Record Into Grid.");
                         return;
                     }
                    String sessionId = listGridRecord.getAttributeAsString("session_id");
                    Date date = listGridRecord.getAttributeAsDate("start_date");
                    getURL(sessionId, date);
               } catch (Exception e) {
                   SC.say(e.toString());
               }
          }
    });

2. getting url from server :

private void getURL(String sessionId, Date date) {
    try {
          CallCenter.commonService.findSessionMp3ById(sessionId, date, new AsyncCallback<String>() {
               @Override
               public void onSuccess(String urlAddress) {
                   if (urlAddress == null || urlAddress.trim().equals("")) {
                       SC.say("Can't find url by sessionId : "+urlAddress);
                       return;
                    }
                //////////////////////////////////////////////////////////////
                // HERE I WANT TO DOWNLOAD FILE BY URL
                /////////////////////////////////////////////////////////////
              }
             @Override
             public void onFailure(Throwable caught) {
                    SC.say(caught.toString());
             }
        });
    } catch (Exception e) {
         SC.say(e.toString());
      }
}

OK, I did it by simple dew window and place LinkItem on it.
It works fine.
