Configure a remote repo location in jcr-ds.xml

[steven]

I deployed my jackrabbit app on JBoss using JCA and configure the repo 
location in jcr-ds.xml

       <config-property name="homeDir" 
type="java.lang.String">C:\timsrepo</config-property>
       <config-property name="configFile" 
type="java.lang.String">C:\timsrepo\repository.xml</config-property>

is there any way I can change the 'homeDir' and 'configFile' to a remote 
location which requires user authentication? like a Windows shared 
folder or Linux directory?

I tried accessing Windows shared folder and it worked, but without 
authentication:
       <config-property name="homeDir" 
type="java.lang.String">\\machine1\timsrepo</config-property>

Please help.
