--- Comment #11 from Sean Owen <sro...@gmail.com> --- One last post with good news -- this *does* work: Tomcat.addServlet(context, "error_jspx", new error_jspx()); context.addServletMapping("/error.jspx", "error_jspx"); This doesn't, which was my original code: Wrapper w = Tomcat.addServlet(context, "error_jspx", new error_jspx()); w.addMapping("/error.jspx"); The reason being that this call won't pass on the mapping to its parent Context unless the container is started. I have no idea whether it's supposed to work, or not, or what; the NPE down the road is surprising. Thank you for your help. As a long time Apache committer I don't like to bother devs. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
