Re: Have any DynamicByteArrayResource sample?
well, I have some idea:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
.
.
.
add(new Link("download") {
public void onClick() {
WebResponse response = (WebResponse) getResponse();
response.setHeader("Content-Disposition",
"attachment;filename=" + "aaa.xls");
response.setContentType("application/x-msdownload");
response.getOutputStream().write(baos.toByteArray());
baos.flush();
baos.close();
}});
It's work! very easy, like a Servlet, but above codes need some
try-catch-finally block.
