Re: Send file to client via Ajax
Hi Cristian,
I've got it working!
Just place all the following files at the same package and you will get a
working example (I tested them with FF35 and IE7).
import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.ajax.markup.html.AjaxLink;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.model.AbstractReadOnlyModel;
/**

*/
public class TestPage extends WebPage{
private Label text;
private String labelText = Hi!;
private DocumentResourceListener documentResourceListener;
/**
*
*/
public TestPage() {
AjaxLinkVoid link = new AjaxLinkVoid(link) {
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
TestPage.this.labelText = Hi! and donwload image!;
if(target!= null) {
target.addComponent(TestPage.this.text);
String url = documentResourceListener.getURL().toString();
target.appendJavascript(;alert('Hi');window.location.href='+url+';);
}
}
};
add(link);
text = new Label(text, new AbstractReadOnlyModelString() {
private static final long serialVersionUID = 1L;
@Override
public String getObject() {
return TestPage.this.labelText;
}
});
text.setOutputMarkupId(true);
add(text);
documentResourceListener = new DocumentResourceListener(listener, new
MyPdfResource());
add(documentResourceListener);
}
}

Just replace jta-1_1-spec.pdf with your own PDF file on MyPdfResource and

This is just a trick to have component that generates file contents on the

This is just a trick to have component that generates file contents on the
same page! I think you could used mounted resources as well, or just a
dedicated servlet if you want to get file generation out of wicket!

Re: Send file to client via Ajax
Perfect! The label was just used to have something to repaint and show AJAX
was working! The whole thing was intended to provide an example of how to do
something and not the complete means to achieve it. If you feel that will
make the example more clear feel free to edit the Wiki page and add/change
any information in there!

Re: Send file to client via Ajax
Hi,
I was trying to build and Example at work but I had to live... I'll try to
get it working tomorrow and post it here. Essentially I was trying something
similar to this.
http://cwiki.apache.org/WICKET/displaying-content-eg-pdf-excel-word-in-an-iframe.html
I was trying to have a component in a page that implements IResourceListener
and then on the onclick on AJX link have something like
if(target != null) {
target.addComponent(theComponentYouWantToRepaint);
String url = urlFor(ComponentImplementingIResourceListener);
target.appendJavaScript(window.location.href=+url);
}
so, that once component is repaint you get a request back to you page asking
for the resource. This is somehow similar to the example above..
Best,
Ernesto

There is no corresponding urlFor() method.

Betreff: Re: Send file to client via Ajax
Maybe you could repaint via AJAX and then use
target.appendJavascript(window.location.href=´URL´);
Where the URL is the URL of an ILinkListener generating you file... There
was someone asking something similar not long ago.
Best,
Ernesto

why do you want to use AjaxFallbackButton ?
you will not re-paint part of the page
use ResourceLink to download the file
