Just to complete discussion,
right click on link didn't work with AjaxDownload version.

Regards,
Igor


2011/8/24 Igor Racic igor.ra...@gmail.com

 Works by using AttributeModifier for href.
 Any objection to use it with AjaxLink ?

 Thank you and regards,

 Hi,

 It worked in IE7. FF/Chrome option setting to download in fixed directory
 played here. I changed to ask on every download and now it works (both
 ways !).

 Is there a way so that right click propose correct name (currenctly it's
 like xyz.htm / xyz.htm.part) ?


 Thank you and regards,

 Igor,

 Don't use the AJAXDownload class. There's another way to do it via Ajax,
 and
 get the Save As dialog.

 Click this page:
 https://cwiki.apache.org/WICKET/best-practices-and-gotchas.html

 Go down to the example that starts with or do it like this: (the 2nd
 example in the section Starting download after form submission (Wicket
 1.2))

 This example is using the WebResource.

 [ WebResource export = new WebResource() { ... etc. ]

 Use this WebResource example. Then, add a ResourceLink backed by this
 WebResource.

 I followed it directly and it works. I get the Save As... dialog box and
 the
 file bytes are constructed at the time the link is clicked.

 CODE:
 --

 // Export to Spreadsheet Link

 // 1. Construct a WebResource from Excel bytes
 WebResource export = new WebResource()
 {
@Override
public IResourceStream getResourceStream() {
 ByteArrayResource bar = new
 ByteArrayResource(application/vnd.ms-excel,
 createExcelBytes());
 return bar.getResourceStream();
 }

@Override
protected void setHeaders(WebResponse response) {
 super.setHeaders(response);
response.setAttachmentHeader(report.xls);
}
 };
 export.setCacheable(false);

 // 2. Add a ResourceLink based on the WebResource
 ResourceLink exportLink = new ResourceLink(exportLink, export);

 add(exportLink);

Hi,

I am not able to get save dialog.

Here is the code:

final AJAXDownload download = new AJAXDownload()
{
@Override
protected IResourceStream getResourceStream()
{
return new StringResourceStream(info.srcString, text/plain);
}
 @Override
protected String getFileName() {
return info.proposedFileName;

 };
add(download);

add(new AjaxLinkVoid(download) {
@Override
public void onClick(AjaxRequestTarget target)
{
// do whatever with the target, e.g. refresh components
//target.addComponent(...);

// finally initiate the download
download.initiate(target);
}
});

Any hint to troubleshoot the problem ? (Clicking on link goes directly to
download)
Version is 1.4.17

AJAXDownload Example Doesn't Support Content-Disposition (Save As)

2011-08-22 Thread eugenebalt 
I followed the AJAXDownload example on how to do an Ajax-based file download:

https://cwiki.apache.org/WICKET/ajax-update-and-file-download-in-one-blow.html

It works, but my problem is, I can't get it to support the
Content-Disposition header attachment to do the Save As dialog box. The
file opens *immediately* inside the browser even when I override
setHeader(..) for the ByteArrayResource.  This works with the regular
ResourceLink, but not this AJAXDownload.

Can anyone help how to do this AJAX-based download, but with the Save As
Content-Disposition=attachment, so it gives me a prompt before I download?

CODE:

final AJAXDownload download = new AJAXDownload()
{

@Override
protected IResourceStream getResourceStream() {
// TODO Auto-generated method stub
ByteArrayResource bar = new 
ByteArrayResource(application/vnd.ms-excel,
createExcelBytes());
{
@Override
protected void setHeaders(WebResponse response) 
 
{
response.setHeader(Content-Disposition, 
attachment;
filename=report.xls);
}   
};
return bar.getResourceStream();
}

};
add(download);

AjaxLink exportLink = new AjaxLink(exportLink) {

@Override
public void onClick(AjaxRequestTarget target) {

download.initiate(target);
}

};  


AJAXDownload (from example):
-
public abstract class AJAXDownload extends AbstractAjaxBehavior
{
/**
 * Call this method to initiate the download.
 */
public void initiate(AjaxRequestTarget target)
{
CharSequence url = getCallbackUrl();

target.appendJavascript(window.location.href=' + url + ');
}

public void onRequest()
{
getComponent().getRequestCycle().setRequestTarget(
new 
ResourceStreamRequestTarget(getResourceStream(), getFileName()));
}

/**
 * @see ResourceStreamRequestTarget#getFileName()
 */
protected String getFileName()
{
return null;
}

/**
 * Hook method providing the actual resource stream.
 */
protected abstract IResourceStream getResourceStream();
}
