You mention the use of filters, which leads me to the question of where is it safe to start using a request-scoped object stored in a ThreadLocal? Would it be safe to use in a filter, listener, or only once request processing gets to the servlet?
A different way of asking this question is where/when does Tomcat start the Thread that handles a given request, and what is executed in the context of that thread? (e.g. filters, listeners, other things, servlets of course) Thanks. Leon Rosenberg-3 wrote: > > they are absolutely perfect to reduce parameter pumping through many > layers of code.
