Ilan,
Both your requests to create a csv and a binary file for download are
generally outside of the scope of velocity servlets.
You'd generally do this using a different servlet.
What servlet framework are you using?
For example, in struts, you'd do something like this in an action to create
a pdf file to download.
To create another file type (cvs, binary), you'd simply change the content
type and provide a different file generator.
response.setContentType("application/pdf");
ByteArrayOutputStream memoryOutputStream = new
ByteArrayOutputStream();
BillPdfer billPdfer = new BillPdfer(selectedBill,
memoryOutputStream);
billPdfer.writeBillPdf ();
response.setContentLength(memoryOutputStream.size());
ServletOutputStream out = response.getOutputStream();
memoryOutputStream.writeTo(out);
out.flush();
return null;
You could still use Velocity to create your csv, but you'd do it directly
with Velocity.mergeTemplate rather than via a servlet.
