The compiler driver and classloader used by tomcat does a lot of magic to get it to work. All jsp files named, for example, index.jsp, will be compiled to a class named org.apache.jsp.index$jsp.java. It will be in a directory with the same name as the directory of the jsp file, but that's not represented in the package name.
The classloader knows where the class file will reside, and then strips out everything but the filename part of the URI, prepends org.apache.jsp to it, and loads that class. The base VM classloader CAN NOT load the generated class files. So debugging with an IDE that doesn't have special hacks is a bit difficult. Even if you can convince it to load servlets and debug that code, convincing it to set a breakpoint in some class named org.apache.jsp.index$jsp, and leaving it to figure out which one, is usually impossible. Unless things have changed recently, then go ahead and ignore all this. I know this applied for 4.0.3. > -----Original Message----- > From: Craig R.
