Duh!
Change it to "int count = 0;"...
Not so sure on the second part.

Subject: multipart requests
I'm using comoreilly servlet and MultipartRequest to
upload large numbers of copies of the
same file to the server and as a result I need to index
each uploaded
file. I've rewritten the code in DefaultFileRenamePolicy
to accommodate
this but can't get it to work completely. It renames the
second file by
adding the index 0002 to the end of the filename, then
0003 to the third
and so on. My problem is that I can't get it to add an
index 0001 to the
filename of the first file. My code looks like this. Does
anyone have
any ideas??
public class DefaultFileRenamePolicy implements
FileRenamePolicy {
private boolean createNewFile(File f) {
try {
return f.createNewFile();
}
catch (IOException ignored) {
return false;
}
}
public File rename(File f) {
String name = f.getName();
String body = null;
String ext = null;
int dot = name.lastIndexOf(".");
if (dot != -1) {
body = name.substring(0, dot);
ext = name.substring(dot); // includes "."
}
else {
body = name;
ext = "";
}
int count = 1;
while (!createNewFile(f) && count < 9999) {
count++;
String c = new Integer(count).toString();
StringBuffer ct = new StringBuffer(c);
ct.insert(0,"000");
String newName = body + ct + ext;
f = new File(f.getParent(), newName);
}
return f;
}
}
I have one other problem. I need to recover the size of
the upload
directory after the files have been uploaded. I've
inserted these two
lines of code into DemoRequestUploadServlet,
File upDir = new File(dirName);
out.println("Present size of Upload directory: " +
upDir.length());
and put them right before the line
out.println("FILES:");
But it obviously isn't working because it gives me the
wrong value. My
guess is that it is giving me the string length of the
filenames in the
folder (but I can't see why), so surely I am using the
wrong method. Or
have I put it in the wrong place?
I've tried using the getSize() method, but i can't get it
to compile
without giving me all sorts of error messages. Has anyone
got any ideas
on how to solve this?
Many thanks in advance.
Damian
