Thank you for the tip. I use now the ImageDirectoryGenerator but I
have one problem with it. If I add a file to a directory given as a
parameter and then refresh the site, the xml generated doesn't show
the new file. But whenever I delete anything from this directory,
the changes are showed at once. When I copy new files to the
directory, the changes are showed only after I have restarted the
servlet engine (in my case Jetty, I am using Coccon 2.1.2). What can
cause this strange behaviour? I have tried to set the
"refreshDelay"-parameters for some different values, but the xml
generated by the ImageDirectoryGenerator never changes until I
restart the servlet engine...

Re: DirectoryGenerator problem (was: Re: Listing files from a directory)

[hed <he...@interia.pl>]

I think there is a bug in DirValidity class (nested in DirectoryGenerator
class):

public int isValid() {
if (System.currentTimeMillis() <= expiry) {
return 1;
}
expiry = System.currentTimeMillis() + delay;
int len = files.size();
for (int i = 0; i < len; i++) {
File f = (File)files.get(i);
if (!f.exists()) {
return -1; // File was removed
}
long oldDate = ((Long)fileDates.get(i)).longValue();
long newDate = f.lastModified();
if (oldDate != newDate) {
return -1;
}
}
// all content is up to date: update the expiry date
expiry = System.currentTimeMillis() + delay;
return 1;
}

directory isn't valid only when a file was removed or 'lastmodified' dates
aren't equal.
it is necessary to check a number of files in that directory also...
