I suspect that, unless you remove Tim Buntel's brain, you will only find bits and pieces of how this works. So, you might try to describe what exactly you want to know, other than "everything". That said, here's basically what happens. 1. Web server receives request. 2. Web server module/filter/whatever identifies the URL pattern of the request as a CF request, and forwards the request to the CF server itself, which is listening on its own port. 3. The CF server identifies the file matching the URL pattern. 4. The CF server checks its memory cache for an existing Java class corresponding to the file. 5. If the cache doesn't contain the class, the CF server checks for an existing Java class within the /WEB-INF/cfclasses directory if the "Save class files" option is enabled in the CF Administrator. 6. If it's not there either, the CF server reads the file from disk and compiles it directly to bytecode (no .java file is created). I believe that Jikes is used for this, although I'm not sure. The bytecode is then stored in memory and optionally on disk. 7. The compiled Java class is executed. The output generated by this is stored in a buffer, then returned to the web server after completion. 8. The web server returns it to the browser. If you have any questions about specific portions of the process, let me know and I'll answer them if I can.
