As with any development tool, sooner or later you're going to find yourself debugging or trouble shooting a ColdFusion problem. Many applications and interfaces have to work seamlessly for a ColdFusion application to function correctly. The key to quickly isolating and correcting problems is a thorough understanding of ColdFusion, data sources, SQL syntax, URL syntax, and your Web server—and more importantly, how they all work with each other.
If the prospect of debugging an application sounds daunting, don't panic. ColdFusion has powerful built-in debugging and error-reporting features. These capabilities, coupled with logical and systematic evaluation of trouble spots, will let you diagnose and correct all sorts of problems.
