I was asking the same question not long ago. Here is an easy way to return a pdf from an action method (in this case a Jasper Report): | byte[] data = JasperRunManager.runReportToPdf(compileDir | + report.getReport() + ".jasper", params); | | FacesContext facesContext = FacesContext.getCurrentInstance(); | HttpServletResponse response = (HttpServletResponse) facesContext | .getExternalContext().getResponse(); | response.setContentType("application/pdf"); | response.setContentLength(data.length); | response.setHeader("Content-disposition", | "attachment;filename=report.pdf"); | | try { | | OutputStream out = response.getOutputStream(); | | out.write(data); | | out.flush(); | out.close(); | | facesContext.responseComplete(); | } catch (IOException ex) { | FacesMessages.instance().add( | "Error while downloading the file: report.pdf"); | } | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4090891#...
