Thanks , Jeremy,
I tried to use AjaxSubmitLink , to
@Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
final File f1 = new File(path.trim() + "/" + fname);
if (f1.exists()) {
final String fn = f1.getName();
IResourceStream resourceStream = new
FileResourceStream(new org.apache.wicket.util.file.File(f1));
getRequestCycle().setRequestTarget(new
ResourceStreamRequestTarget(resourceStream) {
@Override
public String getFileName() {
return fn;
}
});
}
}
But when i clicked the AjaxSubmitLink, i can not get the popup window for
saving. I mean when i clicked the ajaxsumbitlink, there is nothing , not
like downloadlink to popup window.
can u give me some suggestion?
thanks
