Help with Remoting

[terbooter]

I have my remoting_test red5 application
RTMP part works fine.

Now Im tring to implement simple RemoteObject functionality

In app folder (red5\trunk\dist\webapps\remoting_test\WEB-INF\)
I have 3 configuration files:

1) red5-web.properties
webapp.contextPath=/remoting_test
webapp.virtualHosts=*, localhost, localhost:8088, 127.0.0.1:8088

2) red5-web.xml
<?xml version="1.0" encoding="UTF-8"?>
