nothing happen when click on button
am using vaadin 7.6 and simple file downloader 1.0.4
by using simple file downloader nothing happen when click button
please help me to solve this
and may i know there is any required to compile it's widget
the below one is what am try
SimpleFileDownloader downloader = new SimpleFileDownloader();
addExtension(downloader);
Button button = new Button("Click Me");
button.addClickListener(new Button.ClickListener()
{
public void buttonClick(ClickEvent event)
{
StreamResource resource=getStream(new File("/home/likewise-open/KONNECTBI/kirubakaran.m/Downloads/DL_TSTMDLLD.xlsx"));

}
private StreamResource getStream(File inputfile) {
StreamResource.StreamSource source = new StreamResource.StreamSource() {
public InputStream getStream() {
InputStream input=null;
try
{
input = new FileInputStream(inputfile);
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
return input;
}
};
StreamResource resource = new StreamResource ( source, inputfile.getName());
return resource;
}
File resource is cached
This addon has no special configuration for "cache-control" so the default of 1 day is used... if you want to download a "newer" file with the same name, the old file will be downloaded. This can be avoided with following setting in handleConnectorRequest():
stream.setParameter("Cache-Control", "no-store");
