Roller deployment into JBoss, roller not available

  I followed the instruction to deploy Roller into JBoss using exploded war 
file. But
   
  http://localhost:8080/roller
   
  The requested resource (/roller/) is not available.
   
  Other applications were available (the JBoss is running).  
   
  Thanks for help.
