RE: [Cobertura-devel] urgent----0% coverage

[Mark D. <Mar...@sa...>]

1. e. When you invoke the main method from the instrumented classes, are =
you forking or otherwise running the class in a different JVM?  This JVM =
must terminate before you run cobertura-report

2. You need cobertura.jar in your classpath when running (along with =
log4j.jar)

3. You need the ..\Build\classes folder in your classpath (after =
..\Build\instrumented, of course).  Cobertura can't instrument =
interfaces and classes that do not contain debug information, and it =
does not currently copy these classes to the instrumented directory
