please help me understand if there's anything out-of-the ordinary that I 
need to do to run tomcat with delegation and a simple class loader 
hierarchy.  I quickly reviewed the class loader HOW-TO and nothing 
popped out as how to do this.  

If you mean putting everything -- all the jar files mentioned in that 
document into $CATALINA_HOME/common/lib...
