I want to download a file in my jsf project. At bean side I am getting object of DataHandler. I tried to search many times but I did not found anything related to it. How can I download a file through datahandler object?

DataHandler src = attachment.getAttachment();

ByteArrayOutputStream output = new ByteArrayOutputStream();
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
externalContext.setResponseHeader("Content-Type", src.getContentType());
externalContext.setResponseHeader("Content-Disposition", "attachment;filename=sachin.jpg");

And if anybody knows about a good tutorial on file download and file upload which describes whole process in detail would be great for me.
