I have to admit, that both Tomcat and JNDI are almost a book with seven
seals to me ... But I give it a try ...

It looks like you might really have a class loading issue. Since the
InitialContext might not be correclty set up. What you might try is to
set the Thread context ClassLoader before instantiating the
InitialContext in your SimpleInitialContextFactory class, someting like:
ClassLoader old = Thread.currentThread.getContextClassLoader();
try {
Thread.currentThread.setContextClassLoader(
getClass().getClassLoader());
Context initCtx = new InitialContext();
Context ctx = (Context) initCtx.lookup("java:comp/env");
....
finally {
Thread.currentThread.setContextClassLoader(old);
}
