Just to clarify Jimmy, you don't need to implement your own servlet filter - that is just an example of some of my code getting a service from the ioc registry - anywhere you can access the servlet context you should be able to retrieve the service you want. I'm a bit of a newbie myself with Tapestry, but I'm not sure what benefit the access you are looking for would give - it looks to me like the differences you are talking about are just semantics - the servlet context is available through the web app - the registry is available from the servlet context - the service you want is retrievable from the ioc registry keyed on its interface name. Perhaps what you are looking for is access to the ioc registry from a non web app perspective? I'm sure some of the more experienced Tapestry people on the list can point you in the right direction if that is the case.

If i didn't misunderstand , i have to implement a customized filter under tapestry project. My target is to be able to get my injected service from the Registry object out of tapestry module at run-time, the injected service is global singleton and it is managed by Tapestry IOC module. At run-time, the Registry object is initialized by "public final void init(FilterConfig filterConfig)" method and is saved as an attribute object of ServletContext. I'm just trying to get the Registry object out of Tapestry module with noninvasive way, it seems that in the javadoc of Tapestry, there's no such API that enables user to access injected service through Registry object like: public static Registry RegistryFactory.getRegistry(String moduleName){...}; I think IOC module could use a Map like structure to manage the unique Registry of every TapestryModule, like <ModuleName,Registry> and provide an uniform Interface for other framework to access. jc1001 wrote: > > I forgot to put: > > HttpSession session = req.getSession(false); > > ... in the code below.
