Re: How to Integrate Wicket with Apache POI

[eugenebalt <eu...@yahoo.com>]

It's very easy.

1) In your HTML:

# Export to Spreadsheet 

2) In your Java:

add(new DownloadLink("link", generateExcelFile());


The DownloadLink is a provided Wicket class. Note that generateExcelFile()
must return a File object. If the file already exists, you just read it. If
you need to create a spreadsheet in POI, I recommend something like this
utility method:

public void File generateExcelFile() {

   FileOutputStream fos = new FileOutputStream(new File("report.xls"));
   HSSFWorkbook wb = new HSSFWorkbook();
   
   //...

   wb.write(fos);
			
   fos.close();

}

Sorry; in the previous post, the HTML got rendered.

I meant to write,

1) In HTML:

a wicket:id="link" href="#"   (just create the standard HTML link)

2) In Java, use

add(new DownloadLink(link, file));
