Two Solr Webapps, one folder for the index data?

[Jörg Kiegeland]

I have successfully configured two parallel  Solr webapps , however I 
see that all data gets stored in one folder of my Tomcat installation, 
namely C:\Tomcat\solr\data\index.

How can I configure that each Solr webapp shall store the data in the 
folders I assigned at  <Environment value="individualSolrFolder">, where 
already the Solr scheme etc. resides (so that it get stored at 
individualSolrFolder/data/index)?

Thanks
