Hi All... If you have not seen it yet, be sure to check out the excellant Orion CMP Primer available at: http://www.jollem.com/orion-cmp-primer/ If you do and you decide to download the associated files (rather than type them up yourself) you will find a minor error in revision 1.11 in the application deployment descriptor: /addressbook/etc/application.xml Inside this file, you will find: <application> <display-name>Orion CMP Primer (Sample Application)</display-name> <module> <ejb>orion-cmp-primer-ejb.jar</ejb> </module> <module> <web> <web-uri>orion-cmp-primer-web.war</web-uri> <context-root>/orion-cmp-primer-web</context-root> </web> </module> </application> Apparently, some stuff was renamed at some point and changes to this file seem to have been accidently omitted. For this to work, change it to: <application> <display-name>Orion CMP Primer (Sample Application)</display-name> <module> <ejb>addressbook-ejb.jar</ejb> </module> <module> <web> <web-uri>addressbook-web.war</web-uri> </web> </module> </application> This primer is an excellant bit of work for which I am very gratefull!
