如何在Java EE中将主页映射到“应用程序的根目录”？

Question

Set-Up- I have a JSP - index.jsp and a servlet indexController. indexController forwards request to index.jsp. Execution of index.jsp without execution of indexController is not desired.

Requirements-

1. 'www.mysite.com' should be served by indexController/index.jsp
2. Any request with invalid url should get redirected to 'www.mysite.com'.
3. 'www.mysite.com/index.jsp' should get redirected to 'www.mysite.com'.

My Solution -

1. Map indexController to "/" - I read that this is overriding 'default servlet' and I want to avoid that.
2. Map 'index.jsp' in welcome-file-list: I don't need to explicitly map it science 'index.jsp' is there, it will be automatically taken as welcome file. Doing this doesn't execute indexController. Moreover invalid urls are 'forwarded' not redirected to welcome file.
3. Map error page to home page- This is cheating with yourself. I don't want to hide errors.
4. Use two servlets. One with "/*" mapping, which redirects everything to 'mysite.com'. Second mapped to ""(empty) that actually serves request. - Some mysterious issues here(yet to figure out)

I think, everyone wants to achieve same functionality for their home screen and there are many questions at stackoverflow with similar problems.

Is there any standard solution which solves problem for once and for all.

Answer 1

Simply put a web server before your app server and you can map any URL to any application/page. Also don't publish an app server directly. Are you using Tomcat I presume, so you probably deployed ROOT application, right? (you should go with the web server anyway)
