HttpServletResponse Returns scrambled content

Dear Experts,

I'm having a trouble with the following code, that when returned to the browser, shows the binary content of the file instead of the complete file.

I'm Using Seam 2.2 on Jboss EAP 5...

Thanks a lot!
Dave

public String print()
{
byte[] attachment = soh.getInvoicePdf(); // Oracle Blob Field

FacesContext facesContext = FacesContext.getCurrentInstance();
		HttpServletResponse response = (HttpServletResponse) facesContext.getExternalContext().getResponse();
		        response.addHeader("Content-disposition", "attachment; filename=\"" +"invoice.pdf" +"\"");
                response.setContentLength(attachment.length);
           	    response.setHeader("Pragma", "no-cache");
        	    response.setHeader("Cache-Control", "no-cache");
        	    response.setDateHeader("Expires", 0);
        	    response.setContentType("application/pdf");
		try {
			ServletOutputStream os = null;
			os = response.getOutputStream();
			os.write(attachment);
			os.flush();
			os.close();
			facesContext.responseComplete();
						
		} catch(Exception e) {
			e.printStackTrace();
		}
		
		return null;
}

It was a good idea but it didn't solve my issue...

i found the issue by chance:

 i was using an a4j button instead of an a:CommandButton.

Thanks for your quick reply!
