#2 Problem when using security manager with Tomcat

[Anonymous]

Hi,

I can successfully run my application without the security manager and security filter works great. However, when Tomcat is started with security manager enabled I get the following error:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

java.lang.NullPointerException

any ideas please.
