title: Wildfly App - can't serve static content
body: <p>I'm working on a Wildfly App project and I'm facing a problem.
  I have my web.xml configured and in the webapp folder I have a index.html file.
  At first the page worked page and everytime I went to: "localhost/myapp/" it showed me the page.
  But arbitrarily the server decided to not provide me the page anymore, and now everytime I try to access the page I get a blank page.
  I get a blank page even if I try to go to the resource directly:
  "localhost/myapp/index.html".</p>
  
  <p>In the console I have this stack trace:</p>
