[VFS] Asking for a solution with Zip files
OK, my problem is that I want to create some files in an inexisting
location.
I've understood that i can't resolveFile like
zip:file://c:/temp/toto.zip!/myFile.txt if toto.zip doesn't exist.
But How can I manipulate the URL to create first the file and then create
its son. (The same question is available if the URL is
ftp://myserver.fr/myNotCreatedDirectory/theFileIWantToPut.ext).
Did someone have a tip for me or do I have to parse theURL on my own to do
the trick ?
Thanks in advance...
Stéphane.

I wonder why VFS tries to create the *root* folder.
Maybe the underlaying ftp-client do have some problems in parsing the
directory-listing ... maybe something with language settings.
Could you please provide a listing using a commandline ftp client - I
would like to see how the directory listoutput is formatted.

Try this
private static void main(String[] args) {
try {
StandardFileSystemManager manager = new
StandardFileSystemManager();
manager.setFilesCache(new SoftRefFilesCache());
manager.init();
FileObject fileFtp = manager
.resolveFile("ftp://myAccount:myPassword@myFtpServer.fr/test.html");
fileFtp.createFile();
} catch (Throwable t) {
System.out.println("It doesn't work !! : " + t);
t.printStackTrace();
}
I catch this stack trace :

Do you have some code-sniplet you could provide to see what you do.
Maybe a conditional createFolder like:
if (!fo.exists())
{
fo.createFolder();
}
solve your problem !?

--> I want to create a new file at the root of my ftpserver. Surely the
folder exist ! But the ftp provider seems to try to create it again. I don't
understadn why.
And for sure, the ftp provider supports writing :-)
--> that's a good news :-)

Bad news: The ZipFileProvider does not support creating/updating
zip-files. :-(
--> Really a bad news ! But I'm not able to develop it on my own so, I will
manage to do without

FileObject fo =
VFS.getManager().resolveFile("ftp://myserver.fr/myNotCreatedDirectory/theFil
eIWantToPut.ext");
fo.getParent().createFolder();
fo.createFile();
--> I leave this problem because I've another one to deal with :
When I try to create a file like this
ftp://name:password@myftpserver/aNewFile I catch an Exception like this one
org.apache.commons.vfs.FileSystemException: Unknown message with code

Following the code, I see that i decide to create the folder even if it
exist..
Is it a bug ? FTP Provider is writable ?
Thanks for your help..

If no one else solved your problem in the meantime I will have a look at
it start next week.
--> Thanks a lot. I admit that I'm a bit lost in the code... (but I'm a
beginner with VFS). For what I've seen, It's a hard coded test which throw
an exception when the file doesn't exist. I think it's necessary for the
following code but I can't manage to see where and how...
(And all the other stuff collected this week in the mailinglist. Its
odd, all the time this list is so silent and if I am on vacation there
starts a mailstorm)
--> Oh I see...You've been introduced to Mr. Murphy too :-)
