I'm testing WebDAV now and getting lots of exceptions when 
copying photos from PhotoAlbum.

There are entries like this one:

Caused by: java.lang.OutOfMemoryError: Java heap space

Web server isn't stable in these moments.

javaw.exe consumes about 600Mb of memory. Although I can adjust it 
to use 3Gb of memory, this seems to be a wrong way. Storing big 
attachments in a database is a wrong way. Handling them in-memory is 
a wrong way. They should be handled in another manner. Some kind of 
event-based servlet streams attachments block by block without putting 
any whole octet stream in memory (it seems that stroring attachments 
in database implies this as a consequence).

No matter what I (and you) do, wrong way will constantly show its 
wrongness and limitations.

X-Wiki is far from being perfect yet indeed it's outstanding. I don't 
regret I have spent some time to get it working. I hope, current way 
of handling attachments will be obsoleted soon.
