Andreas,
Can you read the created files/folder using a regular servlet? If you
can do it so, I would advice you to dispatch download requests to this
servlet, read the requested file and then write it in response.
Something like this (in your doPost or doGet):
response.setContentType("application/x-msdownload");
String filePath = getServletContext().getRealPath("/") +
"your-correct-path" + request.getParameter("fileName");
File requestedFile = new File(filePath);
response.addHeader("Content-Disposition", "attachment;
filename=" + requestedFile.getName());
if (!requestedFile.exists()) {
logger.error("file doesnt exist : " + filePath);
}
ServletOutputStream out = null;
RandomAccessFile inputFile = null;
try {
inputFile = new RandomAccessFile(requestedFile,
"r");
Long contentLength =
Long.valueOf(inputFile.length());
response.setContentLength(contentLength.intValue());
out = response.getOutputStream();
byte[] buffer = new byte[4096];
int read = 0;
int totalRead = 0;
try {
while ((read = inputFile.read(buffer)) >
0) {
out.write(buffer, 0, read);
totalRead += read;
out.flush();
}
} catch (EOFException e) {
out.flush();
out.close();
} finally {
if (out != null) {
out.flush();
out.close();
}
if (inputFile != null) {
inputFile.close();
}
}
} catch (IOException e) {
logger.error(e.getMessage(), e);
} finally {
filePath = null;
requestedFile = null;
out = null;
inputFile = null;
}
I hope it helps you finding a way to solve your problem...
Yours,
Marcus Milanez

mmm, I am not sure i got what you mean by "listed", but I will try to
describe to you the situation.
catalina home: C:\Program Files\Apache Software Foundation\Tomcat 6.0
my project folder: C:\Program Files\Apache Software Foundation\Tomcat
6.0\PROTEUS_9
(i build-deploy-run it through NetBeans 6.0.1)
web folder of project(containing pages) : C:\Program Files\Apache
Software Foundation\Tomcat 6.0\PROTEUS_9\web
usersessions folder: C:\Program Files\Apache Software Foundation\Tomcat
6.0\PROTEUS_9\web\UserSessions
an istance of a created folder at runtime is this: C:\Program
Files\Apache Software Foundation\Tomcat
6.0\PROTEUS_9\web\UserSessions\admin_Thu_Apr_24_00.30.09_2008
and here is where i put everything the user downloads or creates, so
that he will b able to retrieve it after the end of session.
If by chance you would like to warn me for the dots '.' in the path name
or the capital letters , I could say tha I have tried to create simple
path names without any dots or special characters and i had the same
problem.
Thnx so much.
Andreas.

Could you please list the part of your code where you list the created
files? Where are they located, inside your webapp folder?
Yours,
Marcus Milanez

Hello and many thnx for interest and help.
Yes, I do see the folders/files created by Java code during runtime with
file viewers, they seem all fine.
But tomcat won't open/see them, and even if i try to put the URL in my
browser I get HTTP Status 404.
The code is pretty much basic, Java.IO , FileReader/Writer and so on.
Tell me please if i can be more specific or I should post something
more.
Thanx a lot,
Best Regards,
Andreas, Greece.

Hi Andreas,
We do pretty much the same here and it is working fine. Could you please
post some parts of your code, so that we can see how you specify your
physical folders? Can you see the folders/files created using a file
viewer ?
Yours,
Marcus Milanez

Assunto: Runtime created files not accessible.Please help.
Hello everyone!
I have developed a jsf(java server faces) web application running on
tomcat 6.0 .
Maybe my questions will be a bit naive, but i kindly ask for your help
since i am not able to find solution myself.
The problem is this:
My web server needs to create new folders and write files in the folders
so that the end user will b able to download later.
The files I download or I create though, and save in my new folders
created at runtime, are not available for tomcat...
I get HTTP Status 404 , and I am unable to open them at runtime back
from the local disk.
So, what should I do to make the newly created folders and files
instantly available in Tomcat without restarting???
And what is the proper place for someone to put his application folder??
Thank you very much for your help...
Andreas, Greece.
