How to Enable Debugging for FO Processor Transformations
Edit online

If you encounter errors when running PDF transformations that use an FO processor, it is possible to enable debugging/logging to help you identify the problem. To enable debugging/logging for FO processing, follow this procedure:
  1. Locate and edit the following configuration file: [OXYGEN_INSTALL_DIR]/tools/config/log4j.xml.
    Note: You need write access to this folder, so if you do not have administrator permissions, you may first need to copy the file to another location where you have write access.
  2. Edit the priority element (inside the root element) and change its value to debug.
  3. Save the file in the original location.
  4. Restart Oxygen XML Editor plugin and re-run the transformation.
    Tip: It is recommended that you use a small input file when trying to reproduce the problem, to make it easier to analyze the data in the log.
  5. Once you are finished with the debugging session, remember to edit the log4j.xml file and change the priority element back to its original value. Otherwise, performance could be affected.
