Thank you very much. I copy paste the .war files into the Alfresco/tomcat/webapps folder, restarted the Tomcat server and then went to the link which was indicated in the book "CMIS and Apache Chemistry in Action", although I had to change it a bit, cause I had Tomcat on port 8080 and the filename of the downloaded file of InMemory Repository was different of whats written in the book. But it all worked. Thanks.
