[jboss-user] [JBoss Seam] - Flex + Seam example not working

[javidjamae]

I tried to get the Flex + Seam example from the wiki working, using the instructions they give:

anonymous wrote : 1. extract files to the SEAM-HOME/examples/remoting/helloworld/view dir
  | 2. run ant
  | 3. deploy seam-helloworld.ear
  | 4. Open a browser and go to http://localhost:8080/seam-helloworld/flexhelloworld.html

I followed these steps exactly using JBoss Seam 2.0.0.GA and JBoss AS 4.2.2.GA. When I pull up the URL, the JBoss console gives me the following, and the client side does nothing when I try to interact with it:
