Chapter 9. Troubleshooting Your ColdFusion Code

Chapter 9. Troubleshooting Your ColdFusion Code

After working through nearly half of this book, you have no doubt come across the infamous “Error Occurred While Processing Request” screen. This is what ColdFusion displays when it encounters an error. Often it is hard to put aside the frustration you feel when this happens, but that is what you need to do so that you can focus on the content of the error message and learn from what it's trying to tell you. ColdFusion error messages are packed with good information, but learning to interpret them can be a challenge for new developers.

When an error happens, you need to correct, or debug, the error so that your script will run correctly. ColdFusion provides support for the debugging process in two important ways. First, you can use the ColdFusion Administrator to append debugging information to the end of each HTML page ColdFusion generates, and second, you can use ColdFusion Studio's built-in debugging features to stop the script at various points to inspect what's happening on the server.
