Java Policy Error?

I am getting the following error in my Tomcat6 log. Can anyone point me in the right direction?

SEVERE: Skipped installing application listeners due to previous error(s)

I've never seen this error myself, but it seems as if there is a security policy somewhere in your installation that is preventing the logging library from accessing system properties. See here: http://tomcat.apache.org/tomcat-6.0-doc/security-manager-howto.html

Is this a fresh installation of Tomcat and Java?

Yes it is a fresh server build and I installed tomcat and java durning installation. Ubuntu server 8.10. I will review the link, thanks for your response.

Hi jdissy , Iam getting the same error too , did you resolve the issue ? could you post it ?
Thank you in advance . Regards

Hello,

I'm having the same problem. Seems to be related to the necessity of signing applets with a certificate. Then the browser should ask for certificate to be accepted. Ok, got this info from:
http://issues.apache.org/activemq/browse/AMQ-1605

But I have no Idea what I should be signing =[

Any clues?

Probably not related. Mango doesn't have any applets.

Thanks, I'll keep looking, since got no results yet.
