I added this line in web.xml
<welcome-file>index.xhtml</welcome-file>
now when I try localhost:8080, I get a response,but the <h:> tags dont render, so when I look at the source code, instead of getting
<link type="text/css" rel="stylesheet" href="style.css" />
I get
<h:outputstylesheet name="bootstrap-responsive.css" library="css"></h:outputstylesheet>
