Subject Re: Tomcat Security Limitation
Date Wed, 10 Oct 2012 16:35:45 GMT
Dear all,

Thanks all for your reply. I managed to get the debug logs on and those logs of interest were
set to WARN (warnings), they gave me an indication to the required security settings and I
finally got it to work !!

I am experiencing another problem now. But at least I got Tomcat security manager out of the
way…..I hope!

Many thanks,
