How to Enable Debugging for FO Processor Transformations

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/logback.xml.
   Note: You need write access to this folder, so if you do not have administrator permissions, you might first need to copy the file to another location where you have write access.
2. Edit the <root> element (inside the <configuration> element), change its level to debug, and save the file.
3. Restart Oxygen XML Editor and re-run the transformation.
   Tip: To make it easier to analyze the data in the logs, it is recommended that you use a small input file when trying to reproduce the problem.
4. Once you are finished with the debugging session, remember to edit the logback.xml file and change the <root> element back to its original value. Otherwise, performance could be affected.
