The Twin Cities Patterns Group will discuss two patterns on May 21.

Fault-Tolerant Telecommunication System Patterns

Will be presented by Tom Evans.

These patterns are available at http://www.bell-labs.com/user/cope/Patterns/PLoP95_telecom.html

A hand-out will be provided. The goal of the discussion will be to generalize these patterns to other enterprise scale 24X7 processes requiring a balance between system and human interaction.

The View Helper J2EE pattern

will also be discussed. The full description is available at http://developer.java.sun.com/developer/restricted/patterns/ViewHelper.html (this site requires free registration).

A very brief discussion of two ways to implement the pattern is available at http://www.ciol.com/content/technology/j2ee/102012201.asp
