help,can't save any changes of a word document in the server,only save in local

Hi,

I have downloaded the slide 2.1 +tomcat 5.28, and installed it as the 
default configure.

I only changed,
1)
added two user accounts user and root in the tomcat-users.xml
2)
add the authority in Domain.xml for /roles/root
  <objectnode classname="org.apache.slide.structure.SubjectNode" 
uri="/files">
                    <permission action="all" subject="/roles/root" 
inheritable="true"/>
                    <permission action="/actions/write" 
subject="/roles/user" inheritable="true"/>
                    <permission action="/actions/read-acl" subject="owner" 
inheritable="true"/>
                </objectnode>

But my problem is that, when I upload a .doc document to the path \files, 
when I visited
http://localhost:8080/slide/files/**.doc, and open with word,
when I change some in the doc file, but I failed to save the .doc file, Only 
I can save the file into the local computer, cannot save any change in the 
server.

anyone has met such problems.

Please give me some help

Thanks advance


Tyshan
