I have deployed my application in jboss 7. It is in the url www.myappurl.com/appname/. But if I go to www.myappurl.com/index.html I see Jboss's landing page that says "Welcome to JBoss AS 7".
How Can I remove that page?
Basically you have to set to false the enable-welcome-root property of the Virtual Server that you are using and specify into the jboss-web.xml that the application is bound into the Root Web Context ("/").
See this tutorial.
Hope it helps. Francesco
