* Common class to locate and execute a service. We can configure this to either look-up for EJB, or use local class Idea is that
* the JSP's need not assume remote. They will work either in a full J2EE architecture, or just with Tomcat JVM.
*
* This is the only class that needs to be configured to adapt Exility between remote/local systems
