- 2.6.1 and 2.6.4 are much alike so documentation of 2.6.4 will fit both.
- Also trying to upgrade to 2.6.4 is recommended
- You can read about CMS in the CMS section at http://wiki.jboss.org/wiki/JBossPortal
- You can grab the source ball of 2.6.4 from http://www.jboss.org/jbossportal/docs/
- You can check out anonymously the source of 2.6.x from "tags" at http://anonsvn.jboss.org/repos/portal/
Did you succeed in using the Cms service? I have the same problem and would appreciate any hints.
