Well, in section 102.2, Registering Servlets, the spec says, that HttpService has to call the Serlvet.init method, when the servlet is registered. And concludes that "therefore, the same Servlet instance must not be reused for registration with another Http Service, nor can it be registered under multiple names. Unique instances are required for each registration." > The obvious work-around would be a servlet delegator. I fear, that the servlet delegator would have to take care to not call init multiple times on the delegate. Likewise the destroy method delegation must be handled with care.
