java.security.AccessControlException: access denied (java.lang.reflect.ReflectPermission suppressAccessChecks)

[Rafael]

Hello i deployed an application wich was working perfectly on
hosted mode on a Tomcat server and i was greeted by a lot of errors,
which, in time, i discovered that they were security exceptions. Since
the only i'd like to achieve by now is to see the app working in web
mode i started granted permission after permission in order to make
things work, regardless of any security issues this might cause.
Anyhow, i am stuck at this error:

java.security.AccessControlException: access denied
(java.lang.reflect.ReflectPermission suppressAccessChecks)

Nevertheless, such permission is granted by the configuration i
established.

¿Does anyone knows of any way i can get past this?

¡Thanks in advance!

PS: I should point out that i am, to sum it up, a nooboid newbie
