Yes it does, it's .fp7

Which is not an extension web server would recognize, could that be the
issue?

Re: Initiating File Download through Ajax is not working

Hi

It's mostly working for me as well, except that the downloaded file has
.html appended to it's name.  Any hints?

Re: Initiating File Download through Ajax is not working

[val360]

final AJAXDownload download = new AJAXDownload() {
  @Override
  protected IResourceStream getResourceStream() {
return new FileResourceStream(theDatabase.getFile());
  }

  @Override
  protected String getFileName() {
return theDatabase.getFile().getAbsoluteFile().getName();  //FIX!!! the
filename gets .html appended to it.
  }
};
add(download);

add( new AjaxLink(download) {
public void onClick( AjaxRequestTarget target ) {
if( theDatabase.isOpen() ) {
target.appendJavascript( alert('The database is open, 
close or pause the
db first.'); );
} else {
download.initiate( target );
}
}
});

And this class is unchanged:

import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.behavior.AbstractAjaxBehavior;
import
org.apache.wicket.request.target.resource.ResourceStreamRequestTarget;
import org.apache.wicket.util.resource.IResourceStream;

/**
 * @author Sven Meier
 * @author Ernesto Reinaldo Barreiro (reier...@gmail.com)
 */
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();
}
