I'm having problem with accessing servlet in Tomcat 7. I am migrating web application from Tomcat 6 to Tomcat 7. But servlet was not able to accessible using servlet/servletName. Our application having more than 500 servlets so at present it is not impossible to change the existing code. We cannot map every thing in web.XML also we don't know how may servlets are there. Is there any other solution for servlet like invoker in Tomcat6 for mapping.
