Codebugger - A software tool for cooperative debugging

Debugging of large-scale systems are essentially cooperative and need colla boration of group developers. However, most existing debugging tools are fo r single developer. With single-user tools, only one developer can operate the debugging process while others are frequently requested to gather befor e the screen of a single computer on solving problems, which makes error lo cation and correction so inconvenient and inefficient. We developed Codebug ger-a cooperative debugging tool for Java that supports group developers to participate in one debugging session and cooperate on solving problems at the same time. This paper introduces principles of cooperative software too ls, the architecture of Codebugger and discusses some technical issues conc erning its implementation.
