We are required to develop a mailing system using any language, as long as we complete the WebApp and test and implement it in a company. My programmer knows well using ASP.net so we have started developing using the language. My professor told us that it is HARD to implement ASP.net WebApps in a web server, he suggests we do it in Java, but we already started it on ASP.net plus learning Java syntax will consume time that will interfere in our project schedules.

Is it really "HARD" to implement ASP.net WebApps in a Web Server? We are Computer Science students and this is for our DBMS subject. Thanks.
