Exception Context Reappearance and Analysis for Multi-Role Collaborative Web System

Abstract

It is difficult for the developers to find the complex causes of the exception effectively and fast. This paper summarizes and analyzes five features of the exception occurred in the multi-role collaborative web system, then constructs a three-layer structure of Web context model which includes subject context, object context and operation context. This model makes the correlation of the contexts between different layers normative, simplifies the analysis of exception context. At last, this paper gives a method for exception capturing and analysis based on context, aiming at the problem of avoiding seeking the causes of exception of the traditional exception handling. Experiment shows this solution is feasible, effective and quickly for exception capturing, recovery and reappearance.
