hi all,
I'm trying to do the same example
(http://magazine.redhat.com/2008/08/12/jboss-drools-how-to-tuning-guvnor-part-1/)..
I created the file Guvnor.properties but I can not log in because I must
enter correct username and password and I do not know how to do that.
I get the following error:
RuleAgent(default) EXCEPTION (Tue Jan 18 15:45:08 CET 2011): Server returned
HTTP response code: 401 for URL:
http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/prova1/LATEST.
Stack trace should follow.

I'm using Guvnor 5.1 and I read that I must modify the file ChangeSet.xml
but I don't understand how.
Can anyone help me?
Thanks
Erika
