From Tutorial on Java for Middle tier in Computing Portals Tutorials at ACM Java Grande Meeting -- June 14 99. by Tom Haupt


1 can play both client and server
  • in client/server you trust the server, but not the clients
2 evolve continually
  • objects delegate parts of their implementation to the other objects (also dynamically composed at runtime). Because of subclassing, the implementation of an object may change over time
3 interactions are not well defined
  • because of encapsulation, you cannot understand all the interactions between objects
4 are polymorphic (ideal for Trojan horses!)
5 can scale without limit
  • how do you manage the access right to millions of servers?
6 are very dynamic
