<% // example: // <a href="download.jsp?path=img/&name=test.gif">download image</a>
String root = getServletContext().getRealPath("/"); String path = request.getParameter("path"); String name = request.getParameter("name");
response.setContentType("unknown"); response.addHeader("Content-Disposition", "filename=\"" + name + "\"");
try { java.io.OutputStream os = response.getOutputStream(); java.io.FileInputStream fis = new java.io.FileInputStream(root + path + name);
byte[] b = new byte[1024]; int i = 0;
while ( (i = fis.read(b)) > 0 ) { os.write(b, 0, i); }
fis.close(); os.flush(); os.close(); } catch ( Exception e ) { } %>
