For development work, You may disable the Java security manager
in /etc/default/tomcat5 by adding:

# Use the Java security manager? (yes/no, default: yes)
#TOMCAT5_SECURITY=yes
TOMCAT5_SECURITY=no

Please see /usr/share/doc/tomcat5/README.Debian.gz :
  Disabling the security manager is not recommended on production systems
  since a call to System.exit() in a servlet of JSP page would then stop the
  whole virtual machine that is running Tomcat.
