No, this is really simple as an action method.
Why make it any harder than this?
public void exportFileAction(String contentType, byte[] data,
String filename) throws IOException
{
FacesContext facesContext = FacesContext.getCurrentInstance();
OutputStream responseStream =
((HttpServletResponse)facesContext.getExternalContext().getResponse()).getOutputStream();
if (null == responseStream) throw new
AbortProcessingException("responseStream is null");
HttpServletResponse response =
(HttpServletResponse)facesContext.getExternalContext().getResponse();
response.setContentType(contentType);
response.setHeader("Content-Disposition","attachment;filename=\""
+ filename + "\"");
response.setContentLength(data.length);
responseStream.write(data);
response.flushBuffer();
facesContext.responseComplete();
}
public String exportFileWhenClicked()
{
try {
exportFileAction("text/plain", bean.getStringData().getBytes(),
"file.csv");
} catch (IOException e) {
FacesContext.getCurrentInstance().addMessage(null,
new FacesMessage(FacesMessage.SEVERITY_ERROR,
"Write Error.", e.getLocalizedMessage()));
return null;
}
return "export file";
}
