Hi,
Also do not forget to set the header so that the save as dialogue box is displayed in
IE...For that you have to set the content-disposition header ..
following is the code from our project..
Class FileOpenAction{
protected final void returnBinaryFile(
HttpServletResponse response,
String filename
String saveAsName)
throws FileNotFoundException, IOException {
response.setContentType(mimeType);
String fileExt =
WebUtil.getFileExtensionFromMIMEType("application/pdf");
setSaveAsHeader(response,saveAsName,fileExt);
File file = new File(filename);
response.setContentLength((int) file.length());
FileInputStream in = new FileInputStream(file);
OutputStream out = response.getOutputStream();
byte[] buf = new byte[4096];
int count = 0;
while ((count = in.read(buf)) >= 0) {
out.write(buf, 0, count);
}
in.close();
out.close();
}
public static void setSaveAsHeader(HttpServletResponse response,String
saveAsFileName,String fileExt){
if(saveAsFileName == null){
return;
}
//to get over a problem in browsers due to which the file name must
have proper extension
if((fileExt != null)|| (fileExt.length() !=0)){
int index1 = saveAsFileName.indexOf(fileExt.toUpperCase());
int index2 = saveAsFileName.indexOf(fileExt.toLowerCase());
if((index1 == -1) &&(index2 == -1)){
saveAsFileName = saveAsFileName + "." + fileExt;
}
}
response.addHeader("Content-Disposition", "attachment; filename=" +
saveAsFileName );
}
}
Also another thought..Why use another servlet..Just use another action like we
do..This way you can use all the existing framwroek..Like authorisation etc....

Additionally, In struts framework you have to reset request header before by
call
request.reset();
request.setContentType("application/pdf");
request.setContentLength(byte.length);
