A method of using jarring tool in a wellbore, where the jarring tool is electrically activated to apply an impact force transmitted to at least another tool in the well. The method may further comprise operating a hydraulic mechanism in response to electrical activation of the jarring tool to cause a first member of the jarring tool to be moved to collide with a second member of the jarring tool to apply the impact force. Also, the method may involve electrically activating the jarring tool by communicating at least one command over at least one electrical conductor to the jarring tool.
