Problem with Coldfusion 9 and Solr

Hi,

I have CF 9.0.1 installed, and I'm not able to define a Solr collection.
I get this error in the Administrator:
"An error occurred while creating the collection: org.apache.solr.common.SolrException. Check the Solr logs for more detail."
And in the Solr log, I get this:
"JNDI not configured for solr"

Any hint?

Thanks.
