Thanks Sean and Igor, based on both your responses I've come up with roughly the following which is working:
 
            final String filename = "thefile.csv";
            final String contentType = "text/csv";            
            final String content = "the,content,is,this";

            add(new Link("link"){
                public void onClick(){
                   
                   
                    RequestCycle.get().setRequestTarget(EmptyRequestTarget.getInstance());
                    WebResponse response = (WebResponse) getResponse();
                    response.setContentType(contentType);
                    response.setAttachmentHeader(filename);
                    response.setHeader("Cache-Control", "max-age=0");
                    OutputStream out = response.getOutputStream();
                   
                    try {
                        out.write(content.getBytes());
                        out.flush();
                    } catch (IOException ex) {
                        // ignore
                    }
               
 
                }
            });

Subject: Re: [Wicket-user] Downloading a file generated on the fly


Here's an application  that I wrote.

The application retrieves data from a database and converts it to an Excel XLS file.

I am sending the XLS file to the web browser via the ServletOutputStream.

Note:  DatabaseQueryForm extends BaseForm

I would like to create a text file on the fly and then create a link which will initiate a download of this file.
 
I checked out the example at http://www.wicket-wiki.org.uk/wiki/index.php/UploadDownload#Downloading_Images.  I am thinking that I can do something similar but extend DynamicWebResource.  Then use ResourceLink to link to it... Would this work?  Is there a better way to do it?
