Since <welcome-file-list> only works with physical files, you cannot use a *.jsf filename here since this resolves to a different physical file (like *.xhtml).
To define a welcome file, use one of the following approaches:
- add an index.html file, and include a refresh meta tag in the head:
<head>
<meta http-equiv="Refresh" content="0; URL=your_welcome_page.jsf">
</head>
- add an index.jsp file, and redirect to your welcome page:
<% response.sendRedirect("dropdowns.jsf"); %>
