Using the temp Directory of the current User in jcr-ds.xml

[Sebastian Lindstaedt <Se...@vaberlin.de>]

Hi, 
 
I'm using Jackrabbit in a deployment model 3 scenario and it works like a charm (Kudos to the community! ). 
In my jcr-ds.xml I'm using something like: 
<config-property name="homeDir" type="java.lang.String">/temp/jackrabbit</config-property>
Where temp is a folder that I created myself.
 
Now I would like to do something like:
<config-property name="homeDir" type="java.lang.String">%temp%/jackrabbit</config-property>
Where %temp% points to C:\Documents and Settings\UserName\Local Settings\Temp. The problem is, that I need a folder that I can rely on, on any machine that my JBoss/Jackrabbit gets started on.
Is there a way to use this systemproperty in the jcr-ds.xml?
 
These settings will only be used for a demo, not a productive system! (I'm starting jboss and jackrabbit
directly from a CD and need to save some files in the temp directory of the current user)
 
I'm thankful for any hint,
 
Sebastian
