I have a servlet that generates a pdf file, and returns it inline to be displayed by the browser: res.setContentType("application/pdf"); res.setHeader("Content-disposition", "inline; filename=arajanlat.pdf"); bos = new BufferedOutputStream(out); // Simple read/write loop sends the bytes Sometimes the browser brings up the Adobe Reader plugin, but more frequently it displays a Save As window, saying the mime type is application/octet-stream. It used to work all the time in standalone Tomcat. The server-wide web.xml contains the pdf mime type. Can you give me a hint? Another question: even if the plugin shows, if I want to save the pdf, the offered filename will be the servlets path, not the filename I specified above. Is there a solution for this?
