Abstract: A debugging method and apparatus for developing telecom-class service based on model driven. It is achieved to combine the debugging information of the code debugger and the model display to complete the graphics context debugging of the telecom-class service based on model driven through inversely searching the diagram element according to the code when the graphics context debugging is being carried. The debugging method and apparatus provide debugging ability based on MDA for the telecom-class service development tool, realize to arrive at the actual graphics context debugging not using any simulator, and realize the graphics context debugging of the telecom-class service based on model driven of the remote files.
