Hello,
I'm looking for a way to download a file from the server.
I think I might need to implement something like a File Download Servlet
that should extend HttpServlet, to manage the communication between the
server and the client.
Anyone more expert in this topic could confirm or give me some tips
about this?
Thanks in advance,
Daniel Conde.

Hello Tiago,
I have done like this:
1. create a custom widget (you could let it be unvisible)
2. click a RAP download button, pass infos to js with this widget
3. hide a iframe with download-form inside the js and let this
form-action point to a download-servlet
4. if the browser receives the command for upload, submit this download form
5. download servlet reads the file from memory and begin to download
5. the user could decide to download it or not, if yes, servlet does the
job forward
6. send a response from servlet to browser after download is finished
7. send a request from js to rap and tell rap what rap should do ...
I hope this can help.
Greetings
Wen

Hi,
without having tried it too hard using a button and a browser widget should
do the trick:
Button button = new Button( parent, SWT.PUSH );
button.setText( "push me" );
final Browser browser = new Browser( parent, SWT.NONE );
button.addSelectionListener( new SelectionAdapter() {
public void widgetSelected( final SelectionEvent evt ) {
browser.setUrl( "linkToMyDownload.zip" );
}
} );
The browser could be 'hidden' for example by setting its size to 0,0. For in
memory data the URL should point to an additional servlet or a
servicehandler. Using the Hyperlink component of forms instead of a button
would make it look like a real web link.
Hope that works...
Ciao
