SecureContext timeout in RMI accessing ?

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

After some output ,I get the following exception.
Is there a setting about timeout of SecureContext in RMI?

(the code will be posted after exception )

Exception occured: net.sf.acegisecurity.AuthenticationCredentialsNotFoundException: A valid SecureContext was not provided in the RequestContext

I'm not sure this is a timeout issue.  At the moment, we haven't yet tested with Jackrabbit RMI (it's planned for v1.3).
