Hmm.. are the singleton class files in the reloadable class path, or does
iPlanet have such a concept? We ran into problems with JRun in the early
stages of development when we had non-servlet singleton files in the
reloadable classpath.
If this is true with iPlanet in general, it sounds like a big problem.
Certain system-type services (like custom logging, connection pooling, etc.)
are easy to implement as singletons, especially since there's no way I know
of to load code into the app server's JVM except via servlet initialization.
