I'm no expert here, but for the types of things
in your example, you need to enable the java
system security (also controls access to the 
filesystem, etc).

You enable this by starting Tomcat with the
- security option.  The permissions given to
your app are defined, I believe, in tomcat.policy
(catalina.policy in 4.x) in the conf directory.

Take a look at "Using the Java SecurityManager 
with Tomcat" on the jakarta site
http://jakarta.apache.org/tomcat/tomcat-3.3-doc/tomcat-security.html
