First step question

After installation of Lenya which works fine I followed the steps to setup my 
first publication-publication. I entered the system and was asked to create a 
new page. Unfortunately I got the message

Exception during commit or rollback: 
org.apache.lenya.cms.repository.RepositoryException: 
org.apache.lenya.cms.rc.RevisionControlException: java.io.IOException: Die 
Syntax für den Dateinamen, Verzeichnisnamen oder die Datenträgerbezeichnung 
ist falsch (see logfiles for details)

I concluded that something must be wrong with my access to the file system. 
Unfortunately after two hours I'm not able to solve this:

Here is an output of my publication.xml

 <site-manager name="tree" /> 
  <template id="default" /> 
  <content-dir src="${pubs.root.dirs}/asamc/data/content/" /> 
  <resource-types /> 
  <modules /> 
  <proxies /> 

The failure must be the content-dir
I also tried to give an absolut file path

"file:///D:/data/content/" without any effect.

What I do wrong?

Best regards
