This error message can occur if JBoss 5.1 is used and is due to a change in this version of JBoss. The problem does not occur with JBoss 4.3.

- Close the Documentation window.
- Log off from your SAS Web application (such as SAS Enterprise GRC).
- Start a new session of the Web browser. For example, in Internet Explorer, you would
select File ► New Session. - Restart the SAS Web application.
- Select Help ► Contents.
