How to include failed Request and Responce in junit test report while running

      I am running a test suite which picks up data from a spread sheet and the request is looped to execute all the rows of test data. So when I generate a report after execution, the report dose not contain the Request and Response that was failed. So I want to have the complete Request and Response that got failed during execution in Test Report. we are generating J-Unit Style report.
          Can you please let me know as quickly as possible.

Thank you.
