[xwiki-users] file attachments deleted when jetty restarts

Hi all, I guess there is some trick that I'm not aware of... I have switched to file databases (but cannot copy the existing ones to the filesystem yet, due to problems discussed in another email). When I upload a file, it is created on the filesystem here: /var/cache/jetty/tmp/work/storage/xwiki/Website+Admin/attachment+porter/~this/attachments /var/cache/jetty/tmp/work/storage/xwiki/Website+Admin/attachment+porter/~this/attachments/myrightstoadmin.png /var/cache/jetty/tmp/work/storage/xwiki/Website+Admin/attachment+porter/~this/attachments/myrightstoadmin.png/~METADATA.xml /var/cache/jetty/tmp/work/storage/xwiki/Website+Admin/attachment+porter/~this/attachments/myrightstoadmin.png/myrightstoadmin~v1.1.png /var/cache/jetty/tmp/work/storage/xwiki/Website+Admin/attachment+porter/~this/attachments/myrightstoadmin.png/myrightstoadmin.png but, when i do /etc/init.d/jetty stop it deletes that entire /var/cache/jetty/tmp folder ! Seems obvious to me that since its called /tmp, it means its for temporary storage. So when I start jetty up again, the file attachments cannot be found. Design flaw? Where do I configure the location of the file attachments? Theres nothing in the documentation. cheers Paul
