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.
