The requested resource [/] is not available

My app is up and running, but when I click on view, I get a 404 error page which says "The requested resource [/] is not available". Above it there are some other messages "no global web.xml found" and "Jar contained no TLDs".

I have an xml file with all the welcome page and servlets mapping within it. But I don't know if it is in the jar though.

In the last message, it has

at=info method=GET path="/"

But since I already have my welcome page set, I don't know what to do about this. Here is my welcome file

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
