| ClassReloader | | public class ClassReloader extends ClassLoader (Code) | | A special classloader useful for testing j2ee-like scenarios.
In some tests we want to be able to emulate "container" frameworks,
where code runs in a hierarchy of classloaders, and certain classes may
be loaded by various classloaders in the hierarchy.
Normally this is done by having certain jars or class-file-directories
in the classpath of some classloaders but not others. This is quite
difficult difficult to integrate with the build process for the unit
tests though; compiling certain classes and having the output go into
places that is not in the default classpath for the unit tests would be
a major pain.
So this class takes a sneaky alternative approach: it can grab any class
already loaded by a parent classloader and reload that class via this
classloader. The effect is exactly as if a class (or jar file) had been
present in the classpath for a container's "shared" classloader and
been present in the component-specific classpath too, without any messing
about with the way unit test code is compiled or executed.
