Well this one aint easy but we are making just a little progress
The final line of the java log show that the files were actually uploaded ok. I checked in my java log for a successful upload and the message is the same as yours.
So something is going wrong after that. It probably is a permissions error but which file? I can see two ways forward. One is just to experiment with permissions and the other is to look at the server logs to see if we can pinpoint the problem.
Here's some background information. The files are uploaded to your system's temp file. It looks like this part is going ok. The java applet then calls a php script – svmanager/myupload.php – and this script copies the uploaded files into the gallery.
What permissions do you have on on the myupload.php file and what permissions are on the gallery folder and the images folder inside it? You can experiment with changing these – make a note so you can change them back.
Incidentally, I see that you have a Windows server. Some Windows servers do not allow you to change the permissions with ftp so check that the permissions are actually changing. Go back and look at them again after you've tried the change.
Many (but not all) hosts give you access to the detailed server access logs. These keep a log of every single request from the browser to the server so they are pretty long and unfriendly but they are a very valuable source of information. Look at your server with ftp and see if there's a folder called logs or something similar. There will probably be lots of files in there, often having file names with sequential numbers or dates so you can tell which one is the latest. They are just text files. The entries are time-stamped so if you know the time that you tried to do an upload then you should be able to go straight to that entry.
This is what I see for a successful upload on my local test machine:
127.0.0.1 - - [15/Oct/2009:09:09:15 +0100] "GET /path/svmanager-trunk/uploader/myuploader-source-signed-1.12.2.jar HTTP/1.1" 304 -
127.0.0.1 - - [15/Oct/2009:09:09:19 +0100] "GET /path/svmanager-trunk/uploader/labels.jar HTTP/1.1" 304 -
127.0.0.1 - - [15/Oct/2009:09:09:46 +0100] "POST /path/svmanager-trunk/myupload.php?path=%2Fpath%2Fsvmanager-trunk%2Fg1%2Fimages%2F HTTP/1.0" 200 -
::1 - - [15/Oct/2009:09:09:47 +0100] "GET /path/svmanager-trunk/svmupload.php?uploaded=true HTTP/1.1" 200 5927
It's not quite as incomprehensible as it might look. You can see the two GET requests for two java files (.jar) and then the POST to the myupload.php script. The third GET request loads the upload screen back into the browser. Most importantly – no error message.
Bit of a long post but hope it helps a little.
