You don't create them. You don't have access to the Context. Tomcat creates them and sets them on your class loader. You then access them with getResources() and getResources().getContext(). > I think I can create a new StandardRoot if I have a Context, but what > needs to be done to create a proper context for a web application that is > getting auto-loaded by the tomcat container at startup?

If you can't figure out how stuff works from the source fire up a Tomcat instance, attach a debugger and step through the code. Mark I already tried getResources() but it returns null. hence my confusion. As far as I can tell, tomcat is not setting the root or context on my class loader. As for looking through the source, I'm not even sure where to start. Is there a document somewhere that goes through the entire startup process of the tomcat container so I will at least have an idea of where the tomcat is supposed to be doing this? --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
